ABSTRACT:
An improved liquid end for reciprocating pump which has a cylindrical valve chamber communicating with the pump inlet port and the pump outlet port, the valve chamber receiving an intake valve. A lower retainer holding the intake seat in fixed position, an outlet valve, and an upper retainer holding the outlet seat in fixed position and a closure member, all of these elements being slidably positioned in the valve chamber and each of the valves being made in such a way that the valve seat and the valve disc are each reversible, thereby effectively doubling the operating life of the wearing valve components.
