Abstract

The pump is used for pumping plants which feed a joint outlet pressure pipeline and has a number of working pistons for a common outlet. The pulsation of the liquid pump is reduced to prevent pressure pulsation in the pipe system. The pump has at least three working pistons. The constant volume chamber of the pump housing is provided with a compensating piston which is driven by a cam held on the crankshaft. The working cylinder with the compensating piston is connected directly to the common constant swept volume chamber. The common suction inlet chamber of the system is also connected to the working chamber.
