Abstract (en)
[origin: EP2154371A1] The device has a pulsator as a driving element for a main pump head (11) that lies in a conveyor line (15). The head has an operating area (18) with a check valve on a suction side (16) and a pressure control valve (17) on a pressurized side. An operating area (20) of the pulsator stays in direct connection with the operating area of the head over a recovery pipe (12), so that the pulsator intakes oscillating pumping medium (21) from the conveyor line into the head operating area. The operating area of the pulsator is connected with a suction side of the conveyor line via a venting valve.
