HP Seal Head & Check Valve Repair Kit, Inlet & Outlet, .875 Plunger, 60K | HJ-72185957
The HP Check Valve Repair Kit, Inlet & Outlet, .875 Plunger, 60K | HJ-72185957 is a premium, quality repair kit engineered to restore the performance and reliability of 60,000 PSI (4,100 bar) KMT waterjet intensifier pumps equipped with .875-inch plungers. Designed for late-model Neoline intensifier pumps with a poppet-style inlet, this complete service kit rebuilds both the inlet and outlet high-pressure check valve assemblies, helping maintain maximum operating pressure, sealing efficiency, and cutting performance.
Manufactured to meet and exceed equipment specifications, this HJ-72185957 Check Valve Repair Kit helps eliminate pressure loss, reduce internal leakage, prevent premature component wear, and restore consistent water flow throughout the intensifier. Routine replacement of check valve components is essential for maintaining optimum pump efficiency, extending service intervals, and minimizing costly production downtime.
Every component is precision-machined using premium materials to withstand the extreme operating conditions found in industrial waterjet systems. Properly functioning check valves ensure one-way water flow, stabilize pressure generation, and improve overall intensifier reliability during continuous production.
