Abstract (en)
[origin: WO2020120234A1] The invention relates to a method for operating a piston pump comprising: a differential cylinder drive (1) having at least two differential cylinders (2, 3) for driving at least two delivery pistons that can move in delivery cylinders, wherein each delivery piston is driven via an associated differential cylinder (2, 3) of the differential cylinder drive (1) in order to operate the piston pump; and a hydraulic circuit (4) for driving the differential cylinder drive (1) by supplying hydraulic fluid. Moreover, the invention relates to a piston pump for carrying out the method.
