Abstract: This disclosure presents a pump body, such as a fluid end housing used in a reciprocating pump, which provides an integral seating or engagement surface (or a valve seat integrated with the pump body) for a valve member. The integral engagement surface removes the need for a separate, replaceable valve seat and can last as long as the service life of the fluid end housing. This saves multiple maintenance services during the service life of the fluid end housing, along with the associated down time, labor costs, and material costs for the new valve seats. The integral engagement surface thus performs as an integral valve seat to the pump body. In some embodiments, the integral engagement surface may be coated, heat-treated, or otherwise modified to increase its wear resistance, such as by including one or more wear-resistant inserts to at least partially contact the valve member.
