- Опубликовано: 13 сен 2024
- UPDATE: December 26, 2017
The Maintenance-Free Pump is now available to current owners too! (a few weeks early). Order on our web site, or give us a call.
The Oilless, Maintenance-Free Vacuum Pump for Harvest Right Freeze Dryers is here! It's faster and quieter than the two oil-based pumps we also tested (JB 6cfm Pump, and the new Harvest Right 7.2cfm Pump).
In this video, we discuss the price and measure the noise level and frequency content of the sound of the new oil-less pump. We also measure how long it takes to process a batch of food with the new oil-less pump and compare it to both the new 7.2cfm pump (shipped with all Harvest Right freeze dryers starting in late November 2017) as well as the older 6cfm from JB Industries.
This new oil-free pump is expensive but, like all scroll-type pumps, the machine work must be very precise to operate at such extreme vacuum levels. To learn more about how a scroll type pump works, there is an excellent video here: • Scroll Compressor
As of December 13, 2017, the Oil-Less "Eagle" pump is available as an upgrade when purchasing a new freeze dryer on our web site, and will be available as a stand-alone item in January 2018 for existing Harvest Right owners. For existing freeze dry owners who are interested, you can send us an email or call us to be placed on the waiting list for the January 2018 release.
Our list of freeze dryers is located here:

I've been using the new oilless pump now for about a month and it's worked flawlessly! Pulls a deep vacuum very quickly and is much much quieter than the old pump. My wife and I live in a 750 square foot house so we don't have a garage or basement to dedicate to the freeze dryer. The noise of the old vacuum pump was definitely disrupting but the new one is night and day different. Worth every penny.
Awesome Dan!
There's nothing like scientifically-sound experiments and the metrics they generate to help one make an informed decision. You have convinced me to order my Harvest Right freeze dryer with the oil-free scroll vacuum pump option. Now I just need to see when we can afford it, but it will most definitely be the oil-free option. Thanks for all your hard work creating this video. I'll return the favor by ordering from you when the time comes.
You won’t regret it.
Thanks for taking the trouble to bring in the additional technology as an educational perk. My oil free pump is new, and I’m having a couple of issues, which may be solved by the info provided herein. 🙂
What kind of problems?
The oil less pump is the only way to go. Sooo worth it.
Expensive, but not having to do oil changes each batch is quite a joy.
Can you still say this a year later now?
Excellent job on the comparison, will be calling you shortly for our FD purchase.
The teaser was first class! Come February I'm powering my Harvest Rite up!
Thanks for the teaser comment! That took WAY more time than I planned, but it was sexy don't you think?
Hi Bryan, i got my large HR with oilfree pump last week. I ran 3 cycles, now at the 4th cycle my pump makes noises, like sthg is stucked inside, or scratching on sthg. The sound is really, really noisy and not "healthy" at all... im in Austria / Europe, so its a bit of a challenge to call tech support. Maybe you have an advice for me? Did i do shtg wrong?? Nice regards and thanks for your video btw
Thanks so much for all your really hard work. I have been looking at the Harvest Right for a few years now, and not once was the 'oil' pump issue ever even mentioned. I am in Europe, and if I had ordered two years ago, and only then discovered the 'oil' issue - I would have been enraged. So now I will check out your website!
Great video! I just ordered it from you. I can't wait, no more oil changes!
Hi Steve. Thanks for the order! If you have any other questions give us a call. 541-684-0717
I really wish I could afford a freeze dryer WOW,best present ever.
With great help from Nate at Harvest Right, we (He) managed to help me get the new pump and my FD compatible. With a new fitting on the drum with 5 wraps ( no more, no less) plumbers tape, new hose the pump was able to operate to completion without stopping Halijuya !!
This thing is continually broken. Four months over two rounds of it broken the machine was either off for repairs or waiting for HR to respond to emails. Now it is no longer under warranty and they want us to start paying every time it breaks. I like the machine but the pumps are garbage. The oil one requires to much work and the oil free one doesn’t work long.
I completely agree and am having the same issue 3 years after this latest post. Doesn't appear they have fixed the issues with the oil less pump nor has their service dept improved and the company is not taking responsibility for a crappy product. So frustrated!!
This pump worked flawlessly for almost one year.. then broke... after weeks of diagnosis it was shipped for repairs, it hasn't been the same, works, breaks, works stops working works again on its own. they wouldn't tell me what the issue is with the machine only I have to pay to run a diagnosis......
Thanks for your great experiments and analysis!
I Bought the premier oil pump from Harvest Right.
I was told if you want a commercial quality oil less pump you will spend $8,000
Like new cars, this item will be improved more over the next few years.....Good job!
Perhaps they will come up with new paint color options too. Red just got phased out ;)
Mine is supposed to be delivered today!! I am so looking forward to ditching the oil changes, filters, pump cleaning, all of that messy stuff!! Unfortunately mine was not at the upgrade price. I have had my Harvest Right FD'er for over a year now.
You will LOVE the new pump. Eliminating all the maintenance is such a joy. But it is expensive. We HR owners have all dealt with the maintenance with the oil based pumps and it's totally doable as I'm sure you agree. Up until now, it's been kind of the cost of admission to the world of home freeze drying. Once you have used your new oil-less pump for a few batches, I hope you chime in again with your experience!
I will, when I get it. It wasn't delivered Saturday. I checked the tracking number and it was now with FedX and had not left there yet. I don't know why I received an email saying it would be delivered Sat. Sooooo still waiting, ready to get this show back on the road. Enjoy your videos.
HI Pam, I'm glad you like our videos! I think you may have bought the pump directly from Harvest Right, so you will need to contact them directly about tracking. Had it been purchased from us, you would have received an order confirmation but the tracking number would have been sent when it shipped.
thanks for the info, I'm at a crossroad right now on weather to purchase
the medium unit with the premier pump or the oil less, after reading
and watching the claim that the oil less will need to be rebuild after
so many hours (one or two years) and the cost is upwards $400, any
input on this topic
Epicenter,
Can you do a review of the new industrial (oil filled ) with auto ballast pump?
Thanks
Matt
Hi Bryan,
I just finished my first batch with my new pump. It took about two hours less than with my JB pump so it is definitely faster. I also love how much quieter this thing is too. I just finished washing my trays and then I went to do my routine oil change and then I remembered that is a thing of the past. I'm just waiting on my FD to finish defrosting and I'll be doing another batch. I totally love this thing!
absolutely no maintenance required??....my mind is blown
I know, it's awesome. I'm working on batch number 3 now. It is so nice not to have to drain and filter my oil every time. You do have to change some bearings or something I believe every 8,000 hours or something like that. By the time everybody gets to that point then hopefully there will be some sort of maintenance kit or service offered by HR.
Actually here is the required maintenance:
Seal replacement is needed every 8,000 hours of run time or 1 year. Shaft seals and bearings need to be replaced every 16,000 hours or every 2 years.
Steve Montana and those pieces can be purchased on epicenter?
I'm not sure, I just copied and pasted from Bryan's comment to someone else. Here's what he also wrote in another comment about getting those pieces:
"For more information about seals and bearing replacement call 1-800-865-5584."
I'm sure by this time next year this will be considered a normal process and I'm 100% positive that Bryan will have a how to video on how to do it and will probably sell the parts as well.
So any modern input on all the problems people have been having with these new pumps? I am an industrial mechanic, and would like to know what the requirements are of these pumps.
1, wouldn’t it be cheaper to have a non-C-Phase motor direct drive with a lovejoy coupler to prevent vibratory resonance through the entire machine, and use a catch-can with a baffle for the exhaust to reduce sound levels?
Where can I find a parts list for the pump? Or an exploded view of the internals to find if it’s worth spending that kind of money on one, or setting up a different vacuum pump set up?
this is the same design used in these pumps i will tell you to avoid them they wear and fail after 4 years sometimes sooner . your better off buying a 12 cfm oil pump for 150$ i bought a ebay made in china vac pump and it works better than the original oil pump they provide it also pulls a better vacuum my uncle uses these freeze dryers in his buisness and he has had bad luck with oil free pumps 150 $ 12 cfm 2 stage vers oil free 1,500$ we have oil pumps that are 7 years old and still working . here is that pdf file on these .
iopscience.iop.org/article/10.1088/1742-6596/916/1/012048/pdf
Intro was awesome!
Thanks! It was fun getting those shots together.
just got ours today, first batch with new pump is already running.
How do you like it so far?
Got the oil free pump in 2017 as a gift. Arrived early 2018 and did a batch last night and when the pump turned on, it was making horrible clanking sounds. What? This pump isn't even 3 years old and was over $1700 with shipping. Can't find anyone in my area that repairs them. Harvestright has been notified, awaiting a response.
The clanking is probably the fan housing at the top of of the unit. Mine was damaged in shipping. Just pried it up to clear the fan blades.
Seals died on my Chinee Rotary Vac Pump after WAAAY LESS than the advertised 250 loads. Not happy! Cannot get anybody at Harvest Right to answer the durn phone. Need bearings and seals!
Yes HR can rebuild your pump - Mine did the same thing after only 8 months. HR rebuilt it under warrantee within 2 weeks. That was 18 months ago - no problem since. I run my dryer almost 24/7. Not uncommon for pumps (of any kind) to need rebuilt within 2 years. It's still worth the cost to buy and maintain.
Mine broke twice in the first year. Now it is no longer under warranty so they want to start charging me to keep fixing their cheap crap.
Very informative. Thank you
I think it is time to look for an alternative pump. There has to be something cheaper and better than this pump out there!
It would be interesting to see an update to this video.
1. New machines (screen on top) HR says they’re faster
2. Software now uses a vacuum to help it freeze (faster and more of a difference in pump qualities?)
3. I think they may have updated some parts to the oilless pump then the one here (I assume that makes it work better)
I assume there would be greater differences in all numbers with a greater lead on the oilless setup.
Check out retired at 40 on RUclips. He compares the two but not the oil less pump.
So I take it these do not have a water cold trap,?
You never show how to connect the oil less pump to the harvestrighfreeze
I like your videos... Thank you
Could you show how to clean and maintain the oil free pump!
Great video Bryan. Has me thinking about which way to go. I have the JB pump and oil inside the chamber and hoses at the moment and was thinking about getting the other newer pump but now the oil less version is tempting although not in the budget right now. On top of that I bought the flush kit and extra oil that I would need to get rid of somehow hopefully sell. Decisions decesions
There are a few tricks I've learned about that "oil up the hose issue" that might help you. First, put the pump as low as possible. That makes it harder for oil ever to reach the chamber. Next, the issue seams to be when the FD starts freezing. That slowly creates a vacuum in the chamber that starts sucking oil. You can open the drain valve for a while if you see oil creeping up. Don't forget to close it! Or, you can plug the pump directly into the wall for 20 seconds or so. That pulls the oil down, but also creates a vacuum such that the ball pops up and seals better. Hope that helps.
Thanks Bryan. Do you have any tips for cleaning out the hoses? I probably have 1/2 cup of oil in the main hose. Have had the machine since last spring and this is the first time this has happened and I hope it is the last one way or another.
I guess you could hang it with rags wrapped around the bottom end to drain it. If you really want to clean it out, I use Dawn dish washing detergent to clean my oil drain container. I would bet if you put a solution of hot water and dawn in the hose cans caps the ends with your hands you could swish the solution back and forth. Then empty and run hot water through the hose. Be sure to rinse really well.
Do you have to run them with alcohol for maintenance??? I saw someone comment that you have to do that but when looking at it online I don't see that as maintenance...it says maintenance free. Which is correct? Thanks.
What about building a box around the pump that filters the air and dampens the sound. If constructed properly, it shouldn't overheat the pump. I believe. Your thoughts?
overheat
Does anybody have any info on scroll pump bearing rebuild, including where to get the bearing kit and perhaps a video on the process??
yes
Since I just bought a new JB pump for my freezer drier and repaired my old one, I'll wait a year or two for the price to come down to a few hundred bucks.
I totally understand. You can buy a lot of food to process for the cost of the oil-less pump. You might want to check out this video: ruclips.net/video/pAKeWTumS0g/видео.html ... It's an automatic oil filter set up you could hook up to your JB. I love it. But I'm running the oil-less one now so I can get some hours on it. So far, it just keeps purring with zero issues.
still hasn't come down. o:
Totally appreciate the time and energy spent on showing us all 3 pumps in depth. The green bean batch comparisons showed the facts.
Do you offer lay away option for the “eagle” pump and is there a shipping charge for it ? I bought my HR in October, it came with the JB pump and newer hose.
Hi Lilas, we don't offer the "lay away" program. Since you already have one on lay away, give HR a call and tell them you saw the Eagle pump video. They will be able to upgrade you on the layaway program I'm sure. We can't do that for you. Glad you found the video useful. Be sure to tell them. There would be no extra shipping cost for the Eagle pump if shipped at the same time as the freeze dryer.
EpicenterBryan ok, I understand. I already have my freeze dryer and JB pump. I am considering the layaway program with HR for the oil less pump. Christmas is coming and I have 2 kids in college so funds are tight. Just happy that the company does the lay away program. Thanks again for your video, I watched it twice, very informative. 👍🏼😎
Hello, does it matter where the oil free pump is placed? Above, below or level with the freeze dryer?
Did you ever get an answer for this?
@@Ahmetal nope. But somewhere I’ve read that pump should be on same level as freeze dryer.
Howdy! Thanks for this detailed review :D
For anyone ;)
I am new to this... but how much have you noticed for your power consumption to have increased by using this machine... :D on a constant bases...
Cheers!
It will be interesting to see how the Eagle acts over time with multiple batches! what is the prescribed maintenance with Eagle pump?
Hi Michael, I'm running the Eagle non-stop these days looking for glitches. So far, so good. The manual I received last week says the following:
PUMP MAINTENANCE
In order to make the best use of your investment, familiarize yourself with the
features and operating instructions before starting pump. With routine care and
following proper maintenance guidelines, your pump will give you years of reliable
service. Pumps are designed for deep vacuum work on freeze dryers.
Seal replacement is needed every 8,000 hours of run time or 1 year. Shaft seals
and bearings need to be replaced every 16,000 hours or every 2 years. Replacing
the seals is necessary for achieving deep vacuum and for proper freeze drying.
For more information about seals and bearing replacement call 1-800-865-5584.
EpicenterBryan thanks for the reply! I’ve just completed my first batch on my new freeze dryer and have been enjoying your videos, if I had found you before I purchased I would have bought thru you! Keep the great videos coming! If I can justify the oiless pump you will be hearing from me!
The oil-less pump a big expense, I know. The new oil type pump you have now is a big improvement over the older JB pump. It should perform well for a long time.
@@EpicenterBryan what if you only use 2,000 hours per year, can you change the seals at 3 years then? Or is it a must to change it every year regardless of use?
New subscriber here. Would you recommend this new pump and the freeze dryer in an apartment?? Is the noise louder than a vacuum cleaner, etc. hard to get noise from a video even with the tests you have done which were excellent. OR would you recommend this unit stay in a garage setting??????
The overall noise is like an old dishwasher, or two people having a normal conversation. So my gut would say that you wouldn't want that going on in an apartment at 3am.
Debbie Severance if you watch the video at 8min 57sec he is talking at a fairly normal level, and it is higher then the pump once it settles into its normal constant level. So maybe wouldn’t be too bad?... I have the same concerns. Being conscience of my downstairs neighbors. Did you decide on getting this? If so, have you had any issues?
just got mine in with my new freeze dryer! lets test this thing out
Hey Brian great video as always! I would be interested is knowing the power usage of each pump? Be nice if the eagle also cuts on some of the power bill as well. Thanks!
I don't have specific data but The Eagle and also the new "standard" HR 7.2CFM pumps both use a 3/4HP motor. The JB was a 1/2 HP motor. A 3/4 HP motor is 559.275 watts, and a 1/2HP motor is 372.85 watts. Costs relate to "on time" and your local utility rates per kilowatt hours.... For now, that's all I can offer.
Are you shipping from the US? I purchased my FD in August, do I still need the new Hose? and the hose should come with it!!
Hi Bryan,
I'm "liking" (literally) all your videos I'm watching and subscribed to your channel.
I am curios to know if there is any reason I couldn't run the oil-less pump inverted. (i.e. the motor on the bottom and the vacuum pump on top. I ask cause my house has an unfinished basement. I f I set my soon to be purchased freeze dryer on my kitchen counter then use some plumbing fitting to hard pipe the freeze dryer outlet below my kitchen counter. Then connect the flexible hose to that and run it through my floor and connect to the pump. I could mount the pump inverted to the bottom of my basement floor joices. this would make the freeze dryer a more user friendly home appliance, while confining the majority of the noise to the basement. I understand the vacuum pump needs power from the back of the freeze dryer and all. I am an electrician by trade and work for a commercial HVAC/plumbing/electrical contractor. I have access all manners of info and supplies on a daily basis. I also have a washer drain close by in my basement where I could plumb the drain hose to, making the whole system a much more user friendly permanent type of installation.
thanx for all the great fun and informative videos on freeze drying and the like.
Have a great day.

You will need to give them a call. I've seen similar pumps that have a bracket so they lay on their side. That might make more sense. Perhaps they can get you such a bracket.
I contact HR about this today because you are one of several potential Eagle customers who have asked about Horizontal mounting recently. As soon as I have a response I will know more. The question is if the mechanism can be run horizontally without impacting performance or causing damage. Then, if HR or the pump manufacturer is interested in offering a "cradle" to support the pump in a horizontal orientation. If no harm is caused and they don't want to offer a cradle, I'll look into having them made to offer to customers like you.
Was there a significant difference in energy consumption between the pumps or would that be too hard to measure given this appears to be in a shop with other machines. Curious if anyone can speak to what kind of spike they've seen in bills. Maybe Old Frugal One can speak to it (saw a comment saying you run yours 24/7). In my due diligence phase and want to get my arms around what I'm looking at.
Does the Harvest Right turn it off automatically when pressure is reached? Is this just a stand-alone pump you have to operate manually?
No - the pump plugs into the back of the dryer and is controlled by the dryer. After the dryer calls for the pump to start it will run for the rest of the cycle and shut off at the end.
I do like your video:) Thank you:)
Read a few comments. I’ll just stay w dehydrating. Y’all have fun.
7891234able If you want food that has worse texture, less taste, less nutrients, and food that doesnt last as long, sure...
You get what you pay for.
Good luck eating that in a decade lol
why does your site say : Upgrade to Oil-Free Pump (NOT RECOMMENDED)
NOT??
How many inches of vacuum is it pulling ? The chamber must be leaking or the pump would shut off. Why don't you install a suction strainer and water trap on the inlet hose? 2 small glass jars.
@Yugo Yankoff I WOULD BET NOT.
received my 'new' small freeze dry unit a few weeks ago. it had the 'new' vacuum pump (not the oil less one you are demonstrating) and the unit had some damage.
If your pump was damaged in shipping give Harvest Right a call and they will make it right.
William, did you get your issue resolved?
heya Bryan - Thanks for asking, I sent Brent Johnson an email with pictures of the damage back on December 27th, but haven't heard back from him.
Heya Bryan ... finally got a response from Brent Johnson after I sent the pictures again. I did only purchase the small (stainless steel ) freeze dryer as I wanted to find out how it all works. Have to say I am disappointed with his reply. "the tech guys say it will work fine with the damage and I can either Send it back or get a $250 company credit for purchases". I STILL have not used it yet to see if their techs are telling the truth.
Does this use anymore power than the original version?
great video
The eagle has landed
Right? Doesn't that look like the Lunar Lander?
Bryan, first let me preface my next line of questions with the fact that I am huge fan. A couple weeks ago you introduced the newly improved pump which was a flat out swap from the old pump and now a few weeks later yet another pump (which is almost the cost of my freeze dryer itself). In previous videos you demonstrated that the company would improve subtle things in the design and send out parts like stainless hardware, insulating cushion etc. What is their position on this innovation and the costs associated? Have people in the community sourced similar pumps for less money in the HR forums? $1,600.00 for hobbyists or entry level seems a lot and I am sure that has some mark up with it. I'm interested in your comments.
Hi Ron. I'm not sure where the "stainless hardware, insulating cushion etc" reference came from, perhaps another channel. But I get your point on other comments I have made over the last year. I can not speak for Harvest Right. TheEpicenter.com (my company) is a dealer as of last April / May or so 2017. However, my interest in this product started when the wife and I bought ours with our own cold hard cash in December 2016, and I promptly blew ours up. Thanks to their help, I was back up and running within a week and I posted a video about that.
As far as the $1600 dollar cost on the new pump. I totally get that it would buy LOTS of food to run through your freeze dryer. In trying to clean up the super long video, my point got trimmed.... It is EXTREMELY valid. The added cost for this upgrade is not for everyone. Thus, the lower cost (most common) oil path.
When my JB pump started leaking in April 2017, HR said to send it back under warranty and they would fix it. I told them I would like to buy a spare pump and asked if they would send the parts so I could fix my original pump myself and post how to do it on the channel. They agreed, and that video has now been seen nearly 7,000 times as of this date. Looks like all users of that pump (not just Harvest Right Owners) have run into that problem with that specific pump.
As far as anyone in the HR user community sourcing an oil-less pump like this at a lower price, I'm not aware it has been done. And I say "more power to you", and say go for it. There will be perils, and I say give it a shot if you have some cash and time to play with it. Might work, might not. First, make sure it is 120V, 60hz (not 50hz). Make sure it achieves extremely low mTorr vacuum. What is the magic number? Make your best guess. If it doesn't get that low, does it just take longer or does your food not dry ever? If it doesn't recover fast enough from increasing pressure as the sublimation process progresses from heating the trays and the HR firmware detects an unusual condition and goes into a mode to compensate, what happens? No clue. And if the "self sourced" pump draws more power than is designed and the Harvest Right output relay blows, or the socket melts and burns down your house down, "Who you gonna call? (ghostbusters)" or blame / sue?
That's my put. I say buy the tested name brand. And with Harvest Right's name on these two pumps I know they have been tested with their Freeze Dryers and they will stand behind their warranty, and support the end user with not only replacement parts but debugging and general customer questions.
Fantastic! Thank you Epicenter!
Spread the word! BTW, how did you like that little teaser intro?
What is the address of your site where you sell the FD's and the new oi lless pumps.?
Here is the page you are looking for: theepicenter.com/food-storage/home-food-storage.html
theepicenter.com/food-storage/home-food-storage.html
I am working with HR and have tried several possibilities for leaks. So far no leaks found but still not able to obtain a vacuum. Still trying several possibilities as to why no positive results
Wow, this is very strange. You mentioned you were going to hook up your old JB. Did that work, and were you using your old hose? Keep us updated, please.
I put the little bit of food that’s not finished in the fridge, and bag the rest.
I’m in Toronto, could the freeze dryer and pump be used in an un-insulated garage. I’m concerned about noise levels in the house.
The recommended temperature range for operation is 35-90 degrees Fahrenheit.
I live in Las Vegas and I too don't have room in my house for my large dryer and oil less pump. The noise really isn't bad and I wish I could have it in the house. My garage gets to 120 F in the heat of summer. I had to use a bathroom ceiling fan through the wall and duct cool air from the house through the dryer and return back to the house. I built custom connectors for the duct piping and closed up all the vent holes. It keeps it below 85 F and helps warm the house in winter. The other option is to only use it when the temps are between 35 and 85 F.
@@jerrysmith372 I'm in Las Vegas too. The heat is maddening. I am getting the freeze dryer. I take it one has to keep the pump cool? I plan on using it on the back patio during winter months or in the garage where there is a swamp cooler running. In your estimation would that be ok?
Do you need to clean that outlet valve if it got food particles and how do you do that?
Hi ..... See a reply below from
william kechkaylo
5 months ago
He talks about what he does...
Yes - sometimes stuff can get hung up in the outlet check valve. You'll know when the chamber wont hold vacuum after everything shuts off. The check valve simply unscrews and you can clean it out with water and/or alcohol.
I want to know the life expectancy of the oil less pump
since oil changes are not a thing anymore..lol
Where is the isolation valve?
The product says no User maintenance needed but it actually needs a Pro service every year for bearing replacement and other seals so it means you have to send it in to get it serviced right?
You can usually fix vac pumps w/ kits specifically for them your self. If you are unwilling to learn though you may need help. Its not too hard though.
I’m looking for this kit also.
Someone said this on another site and is it true? "well worth the money that new pump. remember though that you have to clean the pump every few cycles , I do it 4th cycle. just detach the hose from the freeze dryer put 1/3-1/2 cup of iso alcohol into the tube and turn on the pump repeat til it comes out clean. I use 90% iso . I have the large unit. just remember to point the exhaust in a safe direction. I use a box with a clean white towel to absorb it and see if its clean."
Harvest Right does not recommend doing this anymore. They supplied all users with a hose insert to reduce moisture and debris from entering the pump. The new driers and pumps come with a smaller hose. I've had my oil less pump now for 2 years. I don't do any maintenance and I have no problems.
@@jerrysmith372 Thank you.
Which pump will last longer? Say a life cycle cost analysis? Thanks!
That's a great question. I have only been testing this pump for a few weeks. However, pumps of the scroll type have few moving parts. They cost so much because of the precision machining involved. I am told for a pump that can operate at such a low mTorr range, costs can be in the $4,000 range. In the text below the video I mention an awesome animated video that shows how this type of pump operates. It is worth your time to take a look at that. I have been told that this pump can run upwards of 8,000 to 10,000 hours before a $100 gasket set may be needed. I assume it should be cleaned inside at that time.
Bought the new oil-free pump. FD does not work, now! HR sent me a replacement pump and new hoses ( admitting they got a batch of bad hose's mfg in China.) Also replaced the vacuum sensor at the suggestion of one of the techs. I continue to get an error message telling me the FD cannot reach vacuum, or some such message, even after all the things I have tried. About 15 minutes into the drying cycle the machine shuts down, AGAIN! Any suggestion? I guess I will try to resurrect my original JB oil type pump and see what happens. Anyone else had this problem?
Hi Dale, Give me a call when you have a chance. I have a few questions. 541-684-0717
Got the new pump and it works perfect. Did you do a dry chamber test to make sure it is hooked up right?
I am thinking of sending my oil-free pump back. Cost alone $1625 is one reason but the best reason is it does not work. Harvest right is now wanting me to remove the nozzle built into the drum containing the trays. However, I am told it takes a pipe wrench, maybe even using an extension on the pipe wrench to take it off. Not sure that is a good idea since I think it might cause serious damage to the drum. Even if I am successful, install the new nozzle to fit the larger pump hose, And, that does not fix the problem, I must reverse the procedure and re-install my original nozzle to begin using my original pump! However, since using or trying to use the Oil-free pump and find it does not work, I tried to use my original pump and now it only works to a point and it also gets the same message. Not sure what to do at this point but I am into this thing over $6000.
Ours has worked amazingly well. We really love it. Your question about the power outage is a good one. Maybe that is causing a shut down.
Hi Tom: I did not experience an power outage. The pump simply stops at about 15 minutes into the drying cycle. Power to the unit is not a problem. Thanks
however, there IS maintenance to be done on it but very easy to do. you must disconnect the unit from the freeze drier and run iso alcohol into the hose while the pump is on to flush contaminants from the unit. I use 90% about 1/3 cup at a time til the fluid comes out clean, may take a couple times if it hasn't been done for a few cycles. I do it every 3 cycles. just remember to tighten the hose before a new cycle. I forgot once and woke up to a unfinished cycle. oooppps . just retighten and continue.
Where did you find this info? I'm not seeing it anywhere in the manual!
@@TacklingTheGiants from harvest right. they emailed me. HOWEVER !! UPDATE!! this will destroy the pump - harvest right was wrong and they emailed me to stop doing it but not after the pump went out. so now they say to just disconnect the hose from the freezer and run it for 15 - 20 mins to dry the unit inside and so far, it seem to be working no problems to date. after of course i bought a new pump at my cost. thought about a lawyer but, they did help out a bit.
@@williamkechkaylo7915 it doesn't even say to do that now(running it dry after disconnecting)!
@@TacklingTheGiants call them if you have the oil less. talk with the tech guys. remember they ,as most businesses use c.y.a. lol!! or i still have the original emails that i can forward 2 u.
If u order the oil free pump, do u still get the oil pump included with basic package?
No you only get one pump
Excellent Video ! - What is the CFM on the Eagle?
Hi Patrik,
They say it is a 7CFM, but performs more like an 8 or 9CFM. I know that sounds goofy, but the oil based pumps actually loose efficiency as the oil temperature (and water content) increases. So if you think about it in that way and try to compare to an oil based pump I totally get that comparison. I'll be doing a video on that topic....
Very true. Thanks Bryan.
Wow, that pump sounds louder than the old one.
Which pump? They all have a different sound.
If an oil less pump, would you still need a deep freezing dehumidifier component to the sustem, why not just pump it out?
Yes. The freezer captures the water in gas state, and freezes it away from the food on the drum surface.
@@EpicenterBryan I am a Harvest Right user and I have had two standard oil-filled pumps fail. I suspect that the pumps were damaged by water. I realize that much of the water freezes in the inside of the vacuum chamber (as you note in your response to Craig), but some will always get through. Is this new oil-less pump immune to water damage? Is this covered in the pump warranty?
bill main That oil less pump is not your everyday ordinary pump. I’m pretty sure that only used for commercial purposes.
This pump isn’t worth the money. I just got the new industrial pump. Which is the much better deal. The maintenance to this industrial pump. Now I find out they have it. I find it does need maintenance and they do need a 100 rebuild kit. Now my oil less broke. Send back in to be repaired and now I have a pump they sent me since my oiless is broke. This one works better just as quiet and needs less maintenance. I only have to change the oil after every thirty or more load. No filtering. Just drain and replace. I’m out 1500.00. I don’t want the oiless. The one is stronger smaller lighter and overall better pump. Harvestright is like a refund
So you are saying the pump with oil is better?
Rhonda West the newer version they have now and the hose conversion I would not buy the oilless pump
what industrial pump are you using?
xephael sorry it’s not the industrial it’s just the new oil pump they have. Not the old this one has a easy open drain plug
We weren't offered the oiless pump and NOT have to also buy the oil pump. So we paid an extra $1600 on top of the freeze dryer to go oiless!. That leaves us with oil pump that is still in the box, new, unused and an unnecessary expense !
Frustrating.
Do you have an Australian supplier for Harvest Right freeze dryers? I would like to buy one.
For your situation, you will need to contact Harvest Right directly.
Marcus K Hi Marcus, did you have any luck finding an Aust distributor?
We have had our pump for our a few months now and it just got way louder! Is anyone having an issue like that?
Same here! Sounds like there is a loose piece in there
@@CP_HQ Yes, I have had the same issue within a month of new. Had it rebuilt under warranty, just received it back and my first load is loader and sounds like something is wrong still. Not happy with the service dept thus far....hoping they will rectify the issue, these oil free pump is NOT cheap!!
Hey Bryan...See my latest comment, today, regarding the new pump. Dale
Here is the user manual with the specs:

Hi Steve: I cannot access the manual via FB. Do you have a direct link to the PDF of the pump's user manual? Thanks.
Let me contact the person I got it from on Facebook and see where he got it from and I will re-post it.
Never mind. I find a copy on Harvest Right's website!
I just found it there too. I changed the link in my comment. Thanks
Do you leave the oil-less pump on all the time or shut it off between loads?
You must shut it off between loads. If not, you won’t be able to open the door to the food chamber. It’s only function is creating the vacuum.
@@veryinteresting591 lol I didn't make myself clear. I was referring to the off/on switch on the pump. I had ran only one load when I asked the question. Since then I have learned to leave it on. Thank you for your help.
@@tonihay How are you doing now? You must have done enough loads to be confident by now. I've been using my large dryer and oil less pump for 2 years.
If you have questions feel free to reach out.
@@jerrysmith372 Thanks. Yes. I have done many loads and I am comfortable with it. My only regret is waiting so long to buy one.
If I can’t get food , I won’t be able to get oil! Thinking 🤔 no oil .
Just stock up on oil and filters
Dang!!! That’s very expensive 😲
can you believe there are people who are using 7000-12000 usd vac pumps alone ? its mad..
that is one expensive pump!
Yeah, but for those of us that forget to do maintenance, it's a great option.
Ridiculous! Those of us who already have a FD and have nothing but problems with oil getting into our food even AFTER we replace that ball you show how to replace, should be offered these pumps for LESS not MORE! It certainly isn't good PR to have people with machines out there giving them a bad review! It would behoove HR to take care of previous customers to keep them happy and giving good reviews. I have bought 3 and at this point I can't in good conscience recommend them to people I know because of the bad pump!
I've had quite a few bad pumps myself. The JB pumps were never designed for freeze dryers, they were just an off the shelf pump that worked. HR had no idea when they invented this thing that they would have so many issues with the JB pump so it's not their fault. They do have a new HR oil pump for $300 that is supposed to address the flaws in the JB pump. Have you considered calling them and seeing if you could send in one or more of your pumps as a trade in? I did. They already had my spare pump in for repair when I bought this new one so I asked them if I could trade it in on some mylar bags since I no longer needed it as a spare and they said yes. They are very good about working with customers. Even if your current pumps are bad they can still repair them and use them as a replacement for another customer.
Hey CallMe, give me a call. I have a few tips that will help you if you are still having oil in the hose issues with your JB pump. I'll be doing a video about what I learned since I posted that video last year. As far as the new Oil based HR pump goes, I haven't seen any issues with that one yet - but have limited ours using it. Right now I'm trying to get extra hours on the Eagle Pump since it is also new and expensive. But I will be going back to the JB soon. So many people have those, it's important to help resolve these issues.
Hi Steve, you mentioned you had several bad pumps before you got your Eagle. Could you elaborate on what kind of issues, and how long you have had your Freeze Dryer? And I assume issues were all related to the older JB pumps (no longer supplied as of November 20th, 2017)? I don't want to beat a dead horse here, I just think a little more info will heal readers of the thread.
They were all JB pumps. I finally figured out what was happening. I have tons of canned spaghetti sauce that I wanted to freeze dry and every time I did a few batches the pump would start leaking oil like crazy. After the third pump went bad then it donned on me that the acid in the tomato sauce was probably eating that rubber seal.
Another pump just wouldn't power up one day so that was replaced under warranty and when I first got my freeze dryer I could no longer achieve a good mTorr after a while and HR determined that it was the pump and replaced it. So 5 bad ones total. 3 of them were probably my fault though due to the acid.
I've had my FD for two years. Now that I've got the new pump I can get back to freeze drying my spaghetti sauce since it won't damage this pump.
OK, so your problem was mainly with the rear seal. One of the issues with the rear seal on the JB pumps was that it had a steel (not stainless) spring in it which kept the seal tight on the shaft. That combined with the fact that crud could get behind the pump cartridge via the oil channel where the seal was, water could stay in that area (held there by crud). And when the spring rusted, it broke. There was talk that JB was going to change that spring to stainless. I don't know if they ever did or the spare parts channel for that seal ever did.... Perhaps HR gave up on JB because they didn't make the change. I have no insider info on that topic. But I think they have better control with the new pump supplier under their own name. That's a good thing. I wish the USA made company had taken the lead to provide a design that worked and had fewer failures but I guess once you get too big the customer (HR in this case) is not always right. That's why America has lost so much production to other countries.
So before I purchased a Harvest right Standard size in March 2017 and paid over $3K +... I asked one of the engineers at harvest right why they didn't offer am Oil-less version vacuum pump... I was told an oil-less pump would cost an addition 5k in cost! AND that is why they never designed an oil-less pump version ...APPARENTLY THAT WAS A BIG F-IN LIE! My POS freeze dryer constantly upchucks oil when the cycle ends and ruins my batch of freeze dried food.
Your existing JB pump probably has a bad check valve. Check out one of my other videos on the subject. You can contact me via our web site and I'm happy to send you a replacement check valve for you to try. I'll also be posting a video on how to add an external solenoid valve to older JB pumps to fix that issue. For now, move your existing pump as low as you can. Start your FD process, and remove your pump plug from the FD and plug directly into the AC outlet for about 10 seconds and remove. Then plug back into the HR. That will develop a strong vacuum and the check valve will pop up. Give me a call if you need more hints to get you going...
We looked for one about that time and couldn't find one new for under $3,700. These pumps are nice. I want one.
these pumps are JUNK, and harvest right service dept SUCKS,
I tend to agree with you! I had issues with our pump from the start, it's taken me months to get it rebuilt under warranty, just received it back and my first load is louder and something still sounds wrong with the pump. Service dept has not been easy to deal with and after paying a lot for an oil less pump, I'm super disappointed with the product and service. Can you share more about your experience and did they ever rectify your pump issue??
@@julietteg6171 the machine has been sitting idle until we get enough money for a new pump, it's a 3500 dollar paper weight, the machines are junk on many levels, if you get a year out of them praise the lord
how to purchase this from europe?
spacepathfinder1 I believe they sell them in the Uk, but can’t remember the website
@@jean405 tnx i'll try to find it
Here it is. freezefood.uk/Shop/product/home-freeze-dryer-medium/ But the prices are crazy. Buying it from the manufacturer is cheaper
Why is it you do not use a Tesla Vacuum Disk Pump using a shaftless magnetic induction drive A.C/D.C brushless electric motor? And why don't you Americans design and build and manufacture to last as long as it exists? American corporations sure knows how to fool their customers with useless warranties and guarantees when in fact they make everything to last forever, maintenance-free, repair-free, and trouble-free.
@Robert Scott Yeah where can you find a Tesla Vacuum Disk Pump using a shaftless magnetic induction drive A.C/D.C brushless electric motor?
darthvader5300: interesting pump, TDP, but looking over their website applications, there is nothing about "vacuum" applications. It requires something with mass to work, the thicker the better. Hence, TDP work with fluids. In the absence of fluids, a vacuum, the TDP does not work. There is NO Tesla VACUUM Disc Pump. Math calculations show a TDP could possibly reach 95% vacuum using air, but nothing below that. That's why no one uses a TDP to achieve near perfect vacuum conditions! They don't exist!
Shaftless magnetic induction drives do exist. And so do brushless AC/DC motors. How much would you be willing to pay? Do you have a business model that shows people would be willing to pay a whole lot more money to gain a bit more efficiency? Law of diminishing returns.
just a matter of time till someone freeze dry a cat, by mistake...🙀
You are one sick puppy or excuse me one sick kitty!!!
What moron would have that sick thought. I know! A low life piece of Sh___T. I bet your parents wish you were never born. Every time this person looks in the mirror they see a large turd.
@@joec.1906 It was a joke, perhaps in reference to the cat in the microwave stories we have all heard. My kids joked about freeze drying a live cow, but they are kind to all creatures in reality. And I don't think that makes them or me or Plur a low life piece of sh*t.
