Abstract

A piston membrane pump (100) for pumping a liquid, comprising: housing (101) with a chamber (106) having an inlet (107) and outlet (108); a piston (102) in the housing, reciprocating along a longitudinal axis (111) to pump liquid by changing the chamber's volume; a membrane element (103a) sealing the piston (102) to the housing (101); and an actuator (104) driving the piston (102) between a rear (R1) and front end position (F1); and a control unit (105) configured to: control the actuator to drive the reciprocating motion of the piston by using, at different points in time, each of multiple, different sets of end positions (R1,F1; R2,F2; Rn,Fn) for the piston along the longitudinal axis, wherein each set of end positions comprises a rear end position (R1-Rn) and a front end position (F1-Fn) where the distance (L) between the rear end position and the front end position of each set corresponds to a predetermined, full stroke length (L) of the piston.
