ABSTRACT:
The invention consists of a liquid end for a plunger pump, having vertical inlet and outlet, with the suction and discharge valves readily accessible for maintenance without disturbing the suction and discharge piping. The liquid end also includes a relief valve which is accessible without disturbing suction or discharge piping. The passages to and from the relief valve are internal to the housing. Inserts are provided in the valves to eliminate dead space and to facilitate the removal of any trapped air which might adversely affect the performance of the pump.
