Abstract

The present invention generally relates to a pump assembly comprising a valve arrangement adapted to prevent unintended flow of fluid through the pump assembly. The invention provides a pump assembly, comprising a displacement pump (710), an inlet valve (730) allowing a flow of 5 fluid into the displacement pump, and an outlet valve (750) allowing a flow of fluid from the displacement pump. Either the inlet or the outlet valve is a passive valve controlled by a pressure differential across the valve generated by the displacement pump, and the other of the inlet and the outlet valve is an active valve controllable by an actuator. By replacing a traditional passive valve a more compact and cost-effective design can be achieved when compared to a design wherein a safety valve was added as a further valve, just as the energy loss across one traditional passive valve can be eliminated.
