Slowing down the suction stroke leads to a lower stroke
rate and thus to a lower capacity.

You can use the programmable function ‘Pressure stage’ to reduce the
nominal pressure of the pump, thereby minimising the risk of lines rup‐
turing.
The switch-off pressure of the permanently active overpressure monitoring
falls at the same time as the pressure stage - see .
