5.3 Product Specification Electric Booster Pump
To find out under what conditions the installation of an electric booster pump is advised or even
necessary for the smooth operation of PROGUARD Coffee, refer to chapter 3.2: Role and Functionality
of The Main Components of PROGUARD Coffee >> Pump (non-electric).
The following specification simply acts as a guideline to identify an electric booster pump that meets
the technical requirements to help PROGUARD Coffee operate successfully.
Feature
Outlet water pressure
Flow rate
EN
Switch-on/switch-off
function
72
Requirement
3 bar to max. 8,6 bar
Note: The electric booster pump must be installed in front of the
pressure reducer that is connected to the shutoff valve. The pressure
reducer will reduce the (increased) inlet pressure to the maximum
permissible operating pressure of 6 bar
The minimum required flow rate that the electric booster pump needs to
supply to PROGUARD Coffee at the given line pressure is specified in the
table below.
Pressure Flow rate
3 bar 0.35 litre/minute
4 bar 0.5 litre/minute
5 bar 0.7 litre/minute
6 bar 0.85 litre/minute
It is recommended to install an electric booster pump type that is automatically
getting switched-on/off by the measured inlet and outlet water pressure.
Ideally, an electric booster pump is chosen that is equipped with a sensor
to switch the booster pump on or off, depending on the storage tank's water
pressure. Install the sensor at the provided connection at the rear side of
PROGUARD Coffee (John Guest 5/16")
Assuming the booster pump you chose is equipped with a sensor (ideally,
but no must-have), it is the sensor that has to be connected at the rear side
of PROGUARD Coffee (not the booster pump itself).
