All our machines can be built with Rotary Vane Pumps
We offer rotary pumps as plumb in machines and water reservoir machines some of the differences in the 2 pumps are described below. Note that a rotary pump machine with a water reservoir must be built larger than the specifications for the machines to accommodate the pump and motor and reservoir.
Rotary vane pumps:
- Quieter operation when pump and motor is powered on.
- Immediate ramp up brew pressure when pump is engaged.
- Motor separate from pump.
- Brew pressure controlled by adjusting built-in screw.
- A rotary vane pump can extract many more espresso per day than a vibration pump which is why they are used in machines found in high volume cafe’s
- disadvantages, limited warranty from pump manufacturer 90 days
Want a Rotary Pump? It is an add on to most machines.
Vibration pumps have the following benefits:
- Ability to draw water out of a reservoir without damage.
- Lower cost for replacement.
- Less susceptible to buildup of limescale causing agents (calcium and magnesium).
- Handle up to 40 espresso extractions every day.
- Smaller size.
- Built-in passive preinfusion as the pump takes 4-7 seconds to achieve optimal extraction pressure.
- Brew pressure semi-controlled by an overpressure valve (when present in an espresso machine).
- Noisier when refilling boiler (these pumps do go quiet when under full pressure for extraction)
