- Looking to buy a new espresso machine? Which pump will suit you?
There are relative advantages to either pump. Vibratory pumps are smaller, inexpensive and tend to be easier to replace.

Rotary pumps are quieter, offer more consistent pressure, and generally have longer lifespans.
Rotary pumps are powered by a motor (usually made by RPM) and are an integral parts of providing the right pressure for espresso extraction. They are adjustable via the screw fitting on its side and for optimal performance, a water filter and pressure reduction valve should be installed prior to the pump. Commonly rotary pumps are generally made by either Procon or Fluidotec, although other brands are available.
The main difference between pumps is on the connection to the motor, generally, they come in clamp ring 700008, two-bolt 630177 and three-bolt 700009. Pumps using bolt connections need connectors between the pump and motor, however, clamp ring pumps connect directly to the motor.

Great and infomative videos as always! Thank you and please keep it up!
Thank you that was so helpful and clear
Does the pressure gauge on the rotatory pump machine go to 9bar without either blind basket and coffee puck in the portafilter?
Hi Pedro, can you please look at doing a review on the La Pavoni Botticelli Evoluzione PID machine, as I'm getting this machine this week. Thank you :)
thank you very much for your information...but my mahine use vibration pump and last till today for more than 30 years, yes I do not use it more than 20 times a day but almost around 12 times a day 😅
love the candid cough!!! hahahhahahahha!
Thanks for the info, nice to know the diffs. What would be useful is an opinion on the effect (if any) they might have in the brewing process/taste
PS: Really love the subtle Panerai you are rocking there too
Fun times, homie users wanting a quieter pump should use a hand grinder, instead save a lot of money.
I don't have a problem with home users having rotary or gear pumps, by all means, go that way if you can tell the difference in the taste.
With anything mechanical, a well maintained less glamourous machine, will, without doubt, outperform a poorly maintained status symbol.
Regarding the vibrating pumps, the pulsations are happening many times per second, let alone per minute, perhaps a simple purpose-built water hammer reducer could iron that out.
Different pressure levels in the brewing process could be managed by having pressure reducing bypasses accessed sequentially via timer-operated solenoids.
Hi, thanks for the education, Do you think a mazzer super jolly v is an over kill for home use?
hahhaah no, but I'm biased.
In saying that the current Mazzer Supper Jolly E looks nice and solid at home, if you change it to the short hopper of the Mazzer Mini E and have the room.. But it wouldn't be my first choice due to retention.
Would either wait for the New Mazzer Super Jolly V or look at the Eureka Mignon XL.
If budget and room is no issue, the the EK43S :)
Are rotary and vibratory pumps interchangeable ? Say i have a rocket with a vibratory pump. Is it possible to open it up, remove the vibratory pump, and replace it with a rotary pump?
Yes, however you must ensure that the relay and any fusing on the circuit board are both rated for the new pump you wish to use, as rotary pumps tend to use more power than vibe pumps. You also have to ensure you are using the correct starting capacitor as they tend to pull a lot of current when the first turn over.
When using a rotary pump and doing a backwash what happens inside the pump? Does the 9 bar of pressure produced by the pump push back on the impeller and normalise causing it to stay stationary, or is there are 1 way valve on the outlet to prevent the pressure in the coffee path pushing back on to the impeller? Or perhaps it is something else altogether. I would greatly appreciate any explanation on this coz it's driving me crazy xD
The adjustable bypass valve on the rotary pump moves that excess pressure back to the inlet side of the pump.
Do rotary pumps heat up a lot when they are working? Or is this a sign of failure?
They do, but can also be a sign that the bearings in the shaft are starting to need a service.
VERY annoying background music - why?
Appreciate the feedback :)
Will chat with the videographers for future videos to bring it down.
