2.3 Espresso pump
The WMF 5000S has a balanced espresso pump installed.
Unlike standard espresso pumps, this espresso pump regulates to 7.5 bar over the atmospheric pressure - irrespective of the pump input pressure (= line pressure).
Technical service instructions:
In the event that this espresso pump requires readjusting, this can be done without opening the machine.
The set screw for the espresso pump is accessible in its position above the brewer shaft.
Technical service instructions/customer instructions
The espresso pump is NOT self-priming.
Risk of damage to the espresso pump when running empty.
The coffee machine must therefore have an upstream pressure on the line side of 0.2 bar. This means:
Under no circumstances must the coffee machine be operated with a tank which does not have a supply pump between it and the machine.
