Catalogue description records
This discharge valve assembly is built for abrasive-service duty in the fluid end of Kerr KA-3500PT and related pumps, fitting the KA-3500PT, T50 and T50-PT models. On the pressure stroke it opens to release pumped fluid and reseats to hold pressure. The part is an aftermarket replacement for Kerr SKU KA-300HT, listed for identification and fit reference rather than as an OEM-made item. It weighs about 3.75 lb.
A fluid-end valve assembly controls one-way flow through the pump — a suction valve admits fluid on the intake stroke and a discharge valve releases it on the pressure stroke. It typically comprises the valve body, seat, spring and guide.
