Clive, I have watched your videos for years out of interest and curiosity. I recently was working on my dehumidifier whose water pump was not functioning properly. I disassembled the machine and found a nameplate on the solenoid pump which I combined with a few key words on Google only to find your video. I should have known you’d have a video on this very topic. The pump I have is similar in construction but not identical. The operating principle is the same. I had to get this pump operational today so I simply cleaned the gunk and lightly lubricated the culprit o-ring (I know eventually the o-ring will swell a bit when in the presence of petroleum oils) and it worked. I appreciate your videos and all of the interesting stuff you’ve put out over the years. Thank you.
This video has come to my rescue for the second year in a row! Last year it was a blockage, this time that pesky o-ring needed a trim (and when my Dremel attachments didn't do the job, my wife's electronic nail file was just the ticket!). Thank you Clive!
I bought my smoke machine (a cheapy with the pump rammed into the built-in tank) off ebay with a dead pump, wasn't actually dead, just worn out, took it to bits, thought I'd test it while it was open, the piston shot across the room and to date I've still not found it... :P Never needed the machine, I'm just obsessed with electricals... :P
As long as you're looking for it, you'll never find it. The trick is to put it out of your mind, convince it that you're no longer looking for it. Then it will suddenly appear somewhere you're sure you couldn't have missed looking before.
I've encountered the case when diode was blown that I've replaced. Cleaned that with IPA and oxalic acid, washed through with distilled water using veterinary syringe then reassembled. That smoke machine worked at least 8 years after that.Very thorough explanation, thank you, Clive!
Vladimir at first I thought you were saying you could fix a blown diode with IPA and oxalic acid. Was gonna say I've been doing it the wrong way all this time, I've been cleaning my diodes with white vinegar.
Excellent, thank you so much. I used this to fix my steam mop with a 30DCB in it. I'd already dismantled everything else and descaled it and came to the conclusion the pump was the only other thing. It's now working like a dream.
Thank you for this video. Due to your full tear down I was able to determine the plastic housing in the donut hole of the solenoid connecting the piston to the fluid input nipple was broken. I ordered the same pump in this video for my Froggy's Fog F4 Fobble machine. FYI - for those who have my same issue, read on. I had to reuse the black cone shaped o-ring from the output side of the original pump to seal the existing silver metal tubing to the new gold colored nut. I wired it from red to brown and black to blue using Scotchlok UR2 butt splice connectors. I left the diode on the wire. She runs great!
I brough my haze machine home (which is essentially a low output smoke machine and a high output 240 volt fan at the front on a 45 Deg (ish) angle, which disperses the smoke quickly so it doesn't look as frightening when it comes out of the machine) and I was faced with exactly this problem : I knew the pump wasn't working. Lo and behold your channel pops up and the fix of the first o-ring being flattened was exactly the problem the pump was all the way in one direction and wasn't coming back enough off the buffer. Popped in a 6 x 1 mm o-ring (I service air rifles, so I have 1000's in zip lock bags) and would you believe it the bloody thing works again. Now I'm going back to making more Joule thieves (it feels like somehow I'm saying thank you, with the added bonus of keeping the few quid I have in my pocket). Please keep up the excellent work, your channel keeps me going when all around me have failed.
I love your videos! When I saw your video when I searched for fixing my smoke machine pump I knew this one would be the only one I need to watch... Now it's working again - thank you!
Big Clive I sure do appreciate you posting this video. The pump that I had to deal with was in my wife's steam mop. It was a different design but the internals were exactly alike. Save me some money.
It started off looking like a crudely simple device but turned out to have more springs and o rings per square centimetre than any device I've ever seen. Especially tiny ones at that. Thanks for sharing. 😎👌🏼
Thank you for sharing!!!! I work in live audio/production and fixed scores of smoke/hazers but never repaired a pump. It was always the case of ring distributor and sometimes get lucky, sometimes not........Didn't realise that these cheap pumps came apart, off to look through the bone yard of dead machines now!....Thank you, love your channel.
I've been rebuilding fog machine pumps for a few years and this was a very helpful video. I didn't know the little red O-ring was subject to swelling, and I don't have any on hand. I was able to get my existing pump running enough to verify the heater wasn't clogged but I'm not getting the volume of fog I expect from a 1KW. All the other parts look good so I have to assume the tiny red O-ring is the culprit. Thanks for the "class".
Have two small smoke machines here that aren't working after running only a short period of time at all. I'll definitely give it a try to fix one after seeing your video. Thanks for sharing!!!
WOW! You are the man! I had a steam mop just sitting around for over a year because it wasn't producing any steam and your video was just specific enough to help me fix it. One of the springs was not lined up properly so I think the pulsating part wasn't moving as it should. THANKS for this video.
Brilliant video. Exactly the same pump as in a floor mop that I'm trying to repair. The whole heater was blocked with scale. Ive cleaned it and descaled everything. It worked brilliant at first but then stopped. I rechecked and no blockages so i took the pump apart, I can hear it trying so I'm at a loss. Now seeing your great video Im going to bench test it and check that seal is not too tight. Thanks.
Man I wish I had found your video before brute forcing my pump open. Had to cut slots in the crimp of the housing then pry open the crimp. Oh well, luckily the crimp didn't need to be water sealed tight 😊. Thank you for another wonderful, easy to understand video. Love your stuff 👍
Hi you need to change the description as this is the same pump used in the H20 x5 steam mop that often fails because of a blocked pump. Your video saved me buying a new mop.
Thank you so much. I found a Shark steam mop that someone was throwing away. I took it to pieces and thanks to your video it's now working brilliantly. :-D
Wow, what a great detailed and informative video. It didn't really help me with my issue... but it gave me an in depth understanding of how the pump works, and it was fun to watch.
As long as you thoroughly flush it with distilled water afterward, there's no harm in using an acid for cleaning. I use citric acid, as it's more aggressive than vinegar, and less expensive per unit volume if you know where to look. Also, it dissolves solid deposits MUCH better when it's HOT. Thanks for the tear-down and explanation of how it works, Clive! :)
Thank you so much for making this video - just as you described my pump needed a thorough cleaning. I didn't realize they came apart. My pump is working perfectly again thanks to you!!! Pump was from a Bubble Fogger machine - just in time for Halloween. ;)
Thanks, had a fog machine that stopped working after a single season again. Pump hummed but didn’t work. Disassembled and it turned out to be an issue with that very small gasket you were talking about. In this case, the gasket was rubber and didn’t allow proper travel of the metal piece. Scrapped the inside out a little in place with a utility knife. It started working again. To test, you remove this gasket put the pump back together without it and see if it runs.
Now that's handy info as the pumps in some very expensive bean to cup coffee machines are almost identical in operation and cost a small fortune to replace
At 13:04 frame, you can see a ~ 5mm straight "slot" on the metal piece. When pump is activated in our fog machine, water leaks out of this "slot". Other than water leaking from this spot, the fog machine works fine. Any thoughts on why water is leaking here? thnx
Great video. Thanks. In my case, I will need to scrap my OEM pump and buy another. My OEM pump is made of brass instead of plastic. The spring plunger w/ the small rubber head that goes in the brass hole was stuck. The only way I could get it out was to force 100PSI of compressed air from the other side. Once out, I had a hard time to get it back in the hole. I tried sanding the inside of the brass hole w/ 320, 400 and 600 grit sand paper. I cleaned out much of the build-up but the plunger would still not move freely inside that hole. I tried the pump w/ the plunger stuck at the bottom and I tried it without the plunger installed. No luck. Amazon, here I come.... Anyway, thanks for the time you spent putting this video together.
Well i took it apart again and sure enough the solenoid plunger was sticking on the rubber seal. I flied the inner of the seal but although it improved it was still sticking so I used a blade and gently scraped the plastic where the outer par of the seal goes. Its working perfectly thanks. Its an H2O Steam Cleaner. Thanks again.
Excellent video. I had issue with my pump which is very similar. Yes the O ring had swollen preventing the plunger to move back and forth. I too had problems sourcing the correct O ring. I found one that was slightly oversize on the inner diameter and slightly larger on the outer diameter. When fitted it was too tight on the inner. I gently slid the O ring over the shank of a drill bit and with a needle file ran it over the outer whilst spinning in a cordless drill until the fit was perfect. It's now working better than when the smoke machine was new. Thanks again for the tip.
Thanks Clive. Now I know how to take the pump apart in my coffee machine, it's been on a go slow for ages. I might try disconnecting the heating element and put white vinegar through it first.
Word to the (un)wise: If for some reason you brute-force this thing open (ie remove the white plastic cover you normally unscrew the right angle shaft from), when putting it back together the white cover wants to be just so slightly above the contact spacer/stand, about a 16th of an inch. It's also critical that the right angle shaftt is directly in line with the hose connector on the other end (check all sides), otherwise the solenoid inside with either just hum or rattle like mad. I found you can put a slightly thick washer between the stand spacer and the white cover. That will help maintain the correct gap. If you have the gap too small, you won't be able to screw in the right angle shaft and it will keep slipping like it's stripped (it's plastic threads so when push cones to shove, they let go). The diameter of the white cover is larger than the center brass tube and you need this center. The diameter of the right angle shaft will help maintain the correct centering once screwed in but getting the gap, direct center and overall tightness is a science to get it all just right. Slap some alligator clips on a standard 3prong household wire and test your progress in the sink. (Take pictures of which wite goes where - ground is the wire plugged into back of pump if it exists, wire with inline diode goes to hot (black) other wire to white (neutral)). Or it might work either way. I didn't check. Best scenario? Watch bigclive videos before you start tearing things apart the wrong way 😂
Can add counter top ice cube making machines to the list. My mother has one with a pump nearly identical to this one, only difference is a strapped down connector on the output instead of a compression fitting. Been meaning to open it up and see if the pump is crudded up, it doesn't fill properly anymore which is a real shame considering that thing has incredibly good cooling pipes.
@@bigclivedotcom That is an accurate assumpion. There are three wire mesh screens prior to the water reaching the pump in the one I have. The entire unit requires disassembly and cleaning 2-3 times per year. Cheers Clive.
Time to get the fog machine out, last time I ran vinegar thru it I took it out side my son and his friends were playing. They all got ready for smoke and bam vinegar was is the air. I got a laugh.
Hello Clive. I hope you are well. I've been given some of these that don't work and all have been a case of blockage. I'm sure my method of clearing it would not be "Clive Approved" but worked. I had no clue the pump would disassemble that easily. Thanks and have a great weekend.
Pumping fluids at enough pressure to force cleaner to bypass the 2 check valves. There's a magic point in which the valves neither block or pass and that allows water to chase enough blockage through to clear it up.
Thank you sooo much you've earned a subscriber. Before we found your video me and my dad was having a hard time trying to fix ours and we found this video and helped us a lot thank you!!
Clive, how can I send you something? I have a couple of LED light bulbs I have use with a dimmer, and over time, they started to glow yellow and a mysterious brown liquid has appeared within the bulb. I figured you would like to take a look.
If there's a dribble of liquid then it's possible that an electrolytic capacitor has failed and leaked. If it's a lot then a possible scenario is that water from above the ceiling has entered the lamp in some way and caused discoloration and corrosion.
I'm thinking its an issue with the capacitor. The lamps were originally bright white, but after about a month, the lamp decreased in brightness and started to glow a warm yellow light. I replaced it, and the new lamp has the same issue.
With internal combustion engine carburetors, the float bowl gaskets like to swell in the presence of gasoline. One way to try and get it to go back to shape is to either leave it out to off gas or to boil it in some water for 5-10 minutes to drive off all the gasoline. Maybe that would work with those 6mm rings??
My original pump had a third wire for a ground tab. The new pump I ordered looks like the one you have with no ground tab. I hooked it up without it and it works but would you know if this is needed?
(⚠️Innuendo warning!) The last thing you want is a puffed up ring round your shaft! I had an old, cheap air conditioner with one of those pumps for the condensate drainage and it sounded like a woodpecker on speed!
I repaired my smoke machine by using a better pump. What you got there is the cheapest available. It never failed since then. Would you show us a professional pump? Sometimes the heater gets clogged, too. If you use a thyristor you don't need the diode.
In my case the pump was stuck, but I just opened it up as in this video, cleaned it a bit and then tightened the valve part, but maybe 3/4 way through. Turned the pump on and it rang like crazy. Then I disconnected the pump and tightened the valve a bit more, turned it on, it worked and was more quiet. Then I disconnected it again and tightened it fully. It works.
The diode is interesting, why don't they just use the negative half of the sine wave to pull the plunger back? There's probably a good reason for that?
My personal guess would be energy consumption. Having the negative half move current too would double power consumption and isn't neccesary since a spring does the same job as a passive device requiring no power. Not an engineer, but that'd be my guess.
@@picobyte Not the issue. The magnet would not turn off. The piston would stay attracted because the magnetic field needs time to collapse. The solenoid would not have time to cool off either and the coil would burn out. You could have two coils and suck the piston to each end of its stroke using coils at each end but that doubles the cost when in this case a spring is adequate. If you were pumping something thicker you maybe could use the force generated from the other coil instead of a spring. FYI, solenoids are disturbing powerful little things, and simple, and cheap. The tradeoff is one direction power only. If you decide to play with one.... watch your fingers :p
I've stripped my pump down on bubble/smoke machine. Beamz SB2000LED It's model is 30dsb-zjf pump 50hz 18w. My machine works for a while then the smoke seems to stop. Is it the pump or could it be the heater element not heating the fluid? The pump seems to work though. Any thoughts?
If the pump is pushing through liquid then the heater block may be blocked up. It may be possible to dissolve any blockage with a weak acid like white vinegar in water. Complete heater pipe blockage is a fairly common machine failure.
@@bigclivedotcom I'll try white vinegar through it. I've flushed through with distilled battery water after use. Frustration is I've only had it out twice to use and after about an hour the smoke stops and it's just bubbles blowing... Making it an expensive bubble machine lol If I get a new pump off the net... I see they say 500w 900w etc. Does it matter which you get as mine is a 2000w unit.
Thank you for this video. That puffed-up o-ring is exactly what got me wonder 🤔 I'd need a 2 cents part to get smoking again, yet can hardly find any offer below €5 ... for 10 or more of those buggers. I need to find the nearest repair shop and talk rubber seals 🦭 ... Also, your video is awesome 😎👍 - nicely done, friend.
The pump on my machine doesn't whir or vibrate. Is this because a) the pump is toast b)there is some kind of cutout circut on the board? c) does it stop making noise when it is thoroughly clogged? If A, what reading should I get across the leads if the motor is toast. I can hotwire it directly to 120v and expect it to whir up? Thanks (fascinated with things electronical)....
They clog up very easily, particularly when stored for a while. If you take it apart carefully you may be able to unclog it. The solenoid piston should move freely in the cylinder.
back in the days of the old coffee machines with paper filter and ground coffee I remember the smell of hot vinegar sputtering out from the coffee machine during descaling maintenance. Its a foul smell indeed.
Thanks Clive! My old smoke machine has a second live thanks to you! The old o-ring was so puffed up I could never have guessed the size. 6x4x1mm was bang on!
It sounds like the o-rings are the biggest problem in these machines, almost a design defect. Couldn't there be an improvement to the original design by the pump manufacturer, or a repair option, using some kind of "self-lubricating plastic" such as Teflon or Delrin for the o-rings?
Got rid of my 3000 Watt smoke machine last year, after many years of scaring the local kids, only have my crap Martin jewel 24/7 fog machine left that has the usual blocked heater, would love to know where to get another heater from.
What if it's the motor that isn't working? Cuz i was allowed to take home the fog machine from work because it wasn't being used and it heats up but the motor won't work and there's no sound coming from it
Hmmm vinegar steam... Does that kill weeds? This is a terrible idea where I live though, thinking of the neighbors and their outdoor pets. I do actually have a fog machine completely clogged and full of fluid, just as it was when I found it on the street 10 years ago. Maybe it's rubber is totally wrecked but if it's fixable maybe a long pipe on the output could be used to condense and control the steam.
I got a variety of silicone O-rings from Amazon, very reasonable. The ones I got were not metric; not sure if they've got those but probably so. It might help with the stiicking issues.
When servicing hot pressure washers, one must descale the heating coil, which is a coiled steel tube, forming a drum shape into which diesel is sprayed ignited and air forced in with a fan. It gets very scaled quite quickly - a bit like a monster kettle, but angrier. We use hydrochloric acid for this task and it is a pretty scary process, as you are basically dealing with over 100°C steam/water at around about 2500 PSI and so you can imagine what happens when we pour in HCL to this mix! By comparison, a small bit of vinegar in a small copper pipe, well...
Thank you again for this vid clive. I run a fj set in my garage every halloween and i got a fogger last year. Last night it wasnt having it but thanks to your vid, you saved my ass and it is working perfectly now. Happy Halloween!
can they form any reasonable amount of vacuum pressure? im looking for a solusion thats simular to the pressure and colume of somone sucking air through a coffe straw for a desoldering pump

Never needed the machine, I'm just obsessed with electricals... :P
You will probably never ever find it. Its long gone.
It probably teleported into another universe where it will meet all the pens and erasers that were dropped in school and never found again
Zaklamp Don't forget socks and gloves. Really, why is it always my LEFT glove that goes missing?
As long as you're looking for it, you'll never find it. The trick is to put it out of your mind, convince it that you're no longer looking for it. Then it will suddenly appear somewhere you're sure you couldn't have missed looking before.

Thank you 🎉
Big Clive I sure do appreciate you posting this video. The pump that I had to deal with was in my wife's steam mop. It was a different design but the internals were exactly alike. Save me some money.

Thanks for sharing. 😎👌🏼
You, sir, are a gentleman and a scholar! Thank you for the thorough explanation.
after 6 hours of trying this video showed me what step i was missing! thank you
Google the part number, you're the first result and I now have a working steam mop. I should have known Big Clive would have a video on this. Thanks!
Many home espresso machines use these too!
No wonder the things seem to crap out so often. I find the pump makes a ton of noise but nothing happens, and it's almost always the pump that breaks.
That's where I recognised the sound from!
Yeah had one of these pack in and stop my morning caffeine fix. easy enough fix though.
They can wear out on the small coffee pod type machines I think if they are allowed to run dry too often
home ice makers too
My dad used to say of mechanical things: "Son, you can fix most things by taking them apart, cleaning them, and putting them back together."
Yep, exactly.
Good advice!
The mechanical equivalent of turning it off and on.
That was true in the old days, when things were not made shitty and Chinese!
PirateKitty very true sadly.

If the heater core is furring up then white vinegar may clean it.
Just used this to fix my snow machine, works absolutely fine now, thanks for posting.

That suggests a missing or pinched internal seal.
I loved it the way you said it’s coming up to Christmas not long now
I don’t even have a device with this pump, I’m just here for the video
One day you'll find one of these in a broken machine and remember how to fix it.
Great video. Thanks.

Thankfully, the pumps are pretty common and cheap.

It's now working better than when the smoke machine was new. Thanks again for the tip.
Another thing that helps is a dab of silicone grease on the plunger.
Friend! You saved me! It was this damned ring - exactly this tiny shit! I've just enlarged it a bit - and now it works great! Thank You!
Thanks Clive. Now I know how to take the pump apart in my coffee machine, it's been on a go slow for ages. I might try disconnecting the heating element and put white vinegar through it first.
Some coffee machines have a cycle for descaler.
Thanks Clive. My machine works like new :)
Thanks so much! This video revived my smoke machine. Much appreciated! I especially liked the o-ring cheap fix to remove a tiny segment.
I enjoyed the subtle innuendos. Excellent video!
Ah, Innuendos. Italian suppositories.
@@TheAmpair 😂😂😂
Word to the (un)wise: If for some reason you brute-force this thing open (ie remove the white plastic cover you normally unscrew the right angle shaft from), when putting it back together the white cover wants to be just so slightly above the contact spacer/stand, about a 16th of an inch. It's also critical that the right angle shaftt is directly in line with the hose connector on the other end (check all sides), otherwise the solenoid inside with either just hum or rattle like mad.
I found you can put a slightly thick washer between the stand spacer and the white cover. That will help maintain the correct gap. If you have the gap too small, you won't be able to screw in the right angle shaft and it will keep slipping like it's stripped (it's plastic threads so when push cones to shove, they let go). The diameter of the white cover is larger than the center brass tube and you need this center. The diameter of the right angle shaft will help maintain the correct centering once screwed in but getting the gap, direct center and overall tightness is a science to get it all just right. Slap some alligator clips on a standard 3prong household wire and test your progress in the sink. (Take pictures of which wite goes where - ground is the wire plugged into back of pump if it exists, wire with inline diode goes to hot (black) other wire to white (neutral)). Or it might work either way. I didn't check.
Best scenario? Watch bigclive videos before you start tearing things apart the wrong way 😂
Can add counter top ice cube making machines to the list. My mother has one with a pump nearly identical to this one, only difference is a strapped down connector on the output instead of a compression fitting. Been meaning to open it up and see if the pump is crudded up, it doesn't fill properly anymore which is a real shame considering that thing has incredibly good cooling pipes.
These are also commonly used in freestanding dehumidifiers that have automatic pumps for draining.
Yeah, I've heard their distinctive sound in condensate pumps. I'd have thought they'd gunk up quite quickly.
@@bigclivedotcom That is an accurate assumpion. There are three wire mesh screens prior to the water reaching the pump in the one I have. The entire unit requires disassembly and cleaning 2-3 times per year. Cheers Clive.
I wonder if a peristaltic pump would work better, and maybe some kind of sterilising device.
Time to get the fog machine out, last time I ran vinegar thru it I took it out side my son and his friends were playing. They all got ready for smoke and bam vinegar was is the air. I got a laugh.
euuw, yuck 😷 😜
Surly they where pickled.
Must have smelt like a fish'n'chip shop.
Yummy!
Hello Clive. I hope you are well. I've been given some of these that don't work and all have been a case of blockage. I'm sure my method of clearing it would not be "Clive Approved" but worked. I had no clue the pump would disassemble that easily.
Thanks and have a great weekend.
I'll guess forcing fluids through it? That works.
Pumping fluids at enough pressure to force cleaner to bypass the 2 check valves. There's a magic point in which the valves neither block or pass and that allows water to chase enough blockage through to clear it up.
Thank you sooo much you've earned a subscriber. Before we found your video me and my dad was having a hard time trying to fix ours and we found this video and helped us a lot thank you!!
A touch of silicone grease on the o-ring is also a good idea. Once you understand how these things work they are easy to take apart.
Excellent video and the perfect fix for our sandwich steamer. Thanks for sharing!
I knew it! Piston return springs were real!
That inlet check valve: is it opening via water pressure or inertia? I'm guessing the latter, since the pump is drawing water up into the mechanism.
Thanks for this video! I was able to fix my steam mop because of this.
This is most excellent, Explained this pump wonderfully.
Thank you. Got her going using the o-ring delete trick. Haven't tested with juice yet. We'll see how she holds up!
Yes i fixed my K cup based coffee machine which used an almost identical pump. Excellent vid. As usual. Thanks bog C.
England -- the land of spicy volts
That was why early scientists dressed so nattily. Respect for the voltage.
and England was concerned where?
Not forgetting The People's Republic of South Yorkshire ...
@@johnbouttell5827 where men are men and sheep say nothing
I've heard these called 'shuttle' or 'shuffle' pumps as well.
Flushing with alcohol did it for me. Just make sure with fire that all of it gets flushed.
My innuendo warning buzzer has just gone into overload.
Mine's just exploded everywhere - AND so has my innuendo buzzer! 😉
Reciprocation at 50 times a second. That's fast.
Clive, how can I send you something? I have a couple of LED light bulbs I have use with a dimmer, and over time, they started to glow yellow and a mysterious brown liquid has appeared within the bulb. I figured you would like to take a look.
If there's a dribble of liquid then it's possible that an electrolytic capacitor has failed and leaked. If it's a lot then a possible scenario is that water from above the ceiling has entered the lamp in some way and caused discoloration and corrosion.
I'm thinking its an issue with the capacitor. The lamps were originally bright white, but after about a month, the lamp decreased in brightness and started to glow a warm yellow light. I replaced it, and the new lamp has the same issue.
Your detailed instructions just made my smoke machine work again :D
5:45 dat bugger o-ring was too tight. very common problem indeed.
thanks
With internal combustion engine carburetors, the float bowl gaskets like to swell in the presence of gasoline. One way to try and get it to go back to shape is to either leave it out to off gas or to boil it in some water for 5-10 minutes to drive off all the gasoline. Maybe that would work with those 6mm rings??
Here it's the crap alcohol they water down the gasoline with.
My original pump had a third wire for a ground tab. The new pump I ordered looks like the one you have with no ground tab. I hooked it up without it and it works but would you know if this is needed?
(⚠️Innuendo warning!)
The last thing you want is a puffed up ring round your shaft!
I had an old, cheap air conditioner with one of those pumps for the condensate drainage and it sounded like a woodpecker on speed!
I repaired my smoke machine by using a better pump. What you got there is the cheapest available.
It never failed since then.
Would you show us a professional pump?
Sometimes the heater gets clogged, too.
If you use a thyristor you don't need the diode.
Also used in carpet wet extractors as a water/detergent pump as well.
Excellent video, it helped me solve a problem with a smoke machine...
If you wire the red and black wires directly to 110v, on a working pump, will the pump vibrate rather obviously?
The pump often has a diode built in or inline with the cable. So it will run if it's designed for 110V.
In my case the pump was stuck, but I just opened it up as in this video, cleaned it a bit and then tightened the valve part, but maybe 3/4 way through. Turned the pump on and it rang like crazy. Then I disconnected the pump and tightened the valve a bit more, turned it on, it worked and was more quiet. Then I disconnected it again and tightened it fully. It works.
The diode is interesting, why don't they just use the negative half of the sine wave to pull the plunger back? There's probably a good reason for that?
The core isn't magnetic. It would be attracted in on both halves of the waveform.
Core would then need to be a magnet, aka a lot more expensive.
My personal guess would be energy consumption. Having the negative half move current too would double power consumption and isn't neccesary since a spring does the same job as a passive device requiring no power. Not an engineer, but that'd be my guess.
@@bigclivedotcom remove the diode. More smoke. Less runtime per cycle? Maybe full wave just is to fast for the piston to get back to start position.
@@picobyte Not the issue. The magnet would not turn off. The piston would stay attracted because the magnetic field needs time to collapse. The solenoid would not have time to cool off either and the coil would burn out.
You could have two coils and suck the piston to each end of its stroke using coils at each end but that doubles the cost when in this case a spring is adequate. If you were pumping something thicker you maybe could use the force generated from the other coil instead of a spring.
FYI, solenoids are disturbing powerful little things, and simple, and cheap. The tradeoff is one direction power only. If you decide to play with one.... watch your fingers :p
Really helpful video. My pump is broken but has a earth on it but this doesn’t. Do I need to replace it with an earthed pump or is this fine
If it's in a grounded metal case or connected by metal tubing to something that is grounded then it should be OK.
We like BigClive! Thank you for sharing your video and teardown. Things just got a lot simpler. I'll try it!
I've stripped my pump down on bubble/smoke machine. Beamz SB2000LED
It's model is 30dsb-zjf pump 50hz 18w.
My machine works for a while then the smoke seems to stop.
Is it the pump or could it be the heater element not heating the fluid?
The pump seems to work though.
Any thoughts?
If the pump is pushing through liquid then the heater block may be blocked up. It may be possible to dissolve any blockage with a weak acid like white vinegar in water. Complete heater pipe blockage is a fairly common machine failure.
@@bigclivedotcom I'll try white vinegar through it. I've flushed through with distilled battery water after use.
Frustration is I've only had it out twice to use and after about an hour the smoke stops and it's just bubbles blowing... Making it an expensive bubble machine lol
If I get a new pump off the net... I see they say 500w 900w etc. Does it matter which you get as mine is a 2000w unit.
Thank you so much great information. I am going to my Repair bench right now.
Thank you for this video. That puffed-up o-ring is exactly what got me wonder 🤔
I'd need a 2 cents part to get smoking again, yet can hardly find any offer below €5 ... for 10 or more of those buggers.
I need to find the nearest repair shop and talk rubber seals 🦭
... Also, your video is awesome 😎👍 - nicely done, friend.
The pump on my machine doesn't whir or vibrate. Is this because a) the pump is toast b)there is some kind of cutout circut on the board? c) does it stop making noise when it is thoroughly clogged? If A, what reading should I get across the leads if the motor is toast. I can hotwire it directly to 120v and expect it to whir up? Thanks (fascinated with things electronical)....
They clog up very easily, particularly when stored for a while. If you take it apart carefully you may be able to unclog it. The solenoid piston should move freely in the cylinder.
It's _awfully_ similar to the pumps found in espresso machines too!
Alternative use is the pump for a flamethrower...
back in the days of the old coffee machines with paper filter and ground coffee I remember the smell of hot vinegar sputtering out from the coffee machine during descaling maintenance. Its a foul smell indeed.
Thanks Clive! My old smoke machine has a second live thanks to you! The old o-ring was so puffed up I could never have guessed the size. 6x4x1mm was bang on!
😊😢😂😢😢
It sounds like the o-rings are the biggest problem in these machines, almost a design defect. Couldn't there be an improvement to the original design by the pump manufacturer, or a repair option, using some kind of "self-lubricating plastic" such as Teflon or Delrin for the o-rings?
Thank you so much for creating this!
Got rid of my 3000 Watt smoke machine last year, after many years of scaring the local kids, only have my crap Martin jewel 24/7 fog machine left that has the usual blocked heater, would love to know where to get another heater from.
From a Martin dealer if they still stock them. But it may be cheaper to get a new machine.
What if it's the motor that isn't working? Cuz i was allowed to take home the fog machine from work because it wasn't being used and it heats up but the motor won't work and there's no sound coming from it
Do those pumps not use a diode? If they do use a diode would that not cut the pulses in half?
The diode lets the pump operate on a near 50% duty cycle, giving better pumping action.
Thanks. Helped me confirm the problem with my pump.
What is the electrical adapter u used to supply power to the pump?
Hmmm vinegar steam... Does that kill weeds? This is a terrible idea where I live though, thinking of the neighbors and their outdoor pets. I do actually have a fog machine completely clogged and full of fluid, just as it was when I found it on the street 10 years ago. Maybe it's rubber is totally wrecked but if it's fixable maybe a long pipe on the output could be used to condense and control the steam.
Can I buy a pump like this for my steam mop?
I got a variety of silicone O-rings from Amazon, very reasonable. The ones I got were not metric; not sure if they've got those but probably so. It might help with the stiicking issues.
When servicing hot pressure washers, one must descale the heating coil, which is a coiled steel tube, forming a drum shape into which diesel is sprayed ignited and air forced in with a fan. It gets very scaled quite quickly - a bit like a monster kettle, but angrier. We use hydrochloric acid for this task and it is a pretty scary process, as you are basically dealing with over 100°C steam/water at around about 2500 PSI and so you can imagine what happens when we pour in HCL to this mix! By comparison, a small bit of vinegar in a small copper pipe, well...
I love this video but I know I can’t do this myself. Who do I call or go to in order to get my snow machine fixed?
this video came right on time, had a zr44 that needs a date with the screwdriver this weekend...
Thank you again for this vid clive. I run a fj set in my garage every halloween and i got a fogger last year. Last night it wasnt having it but thanks to your vid, you saved my ass and it is working perfectly now. Happy Halloween!
That is brilliant! Thank you so much for your time and help!
Thanks to the sound i now know what kind of pump is beeing used in my steam assisted oven in case it breaks down :)
It's a very common style of pump used in many applications. Another common one is some condensate pumps in air conditioning systems.
What is that portable machine you used to create current to test machine? Thanks
Looks like something else in the wire in addition to the diode.
How about creating some sort of alcohol serving device using one of these :)
the simplicity of gravity works well...
I was pondering if it could be used to make cocktails.
I would definitely prefer a peristaltic pump for alcohol dispensing
can they form any reasonable amount of vacuum pressure? im looking for a solusion thats simular to the pressure and colume of somone sucking air through a coffe straw for a desoldering pump
They're not really designed to run dry.
