A pump system is presented having a pump with a generally cylindrical pump housing that is arranged with a liquid inlet in one end and a liquid outlet in a second end. A tubular membrane is arranged inside the pump housing and a first passage is arranged in the vicinity of the liquid inlet for introducing pressurized fluid between the membrane and the housing. A second passage arranged in the vicinity of said liquid outlet for releasing said pressurized fluid where the membrane is arranged with an elasticity providing a local radial compression and an annular fluid compartment when a pulse of pressurized fluid is entered through the first passage. The annular fluid compartment travels along the housing bringing a volume of liquid with it. An expansion vessel can be operably attached to the liquid outlet for reducing pressure changes in the liquid caused by the action of the pulse of pressurized fluid.
