550 CAT 7 Frame Plunger Pump

These easy maintenance pumps are the most popular plunger pumps for self-service bays with superior triplex plunger design and lubricated seals and V-packings that are cooled by the liquid being pumped. Inlet and discharge valve assemblies interchange for easier maintenance. The oil bath crankcase assures optimum lubrication. Close tolerance concentricity of the ceramic plunger maximizes seal life. 

Quality materials like 304 stainless steel valves and seats are hardened and polished for ultimate seating and extended valve life. The forged brass manifold is strong and corrosion resistant. 
Special concentric, high-density, polished, solid ceramic plungers provide a true wear surface and extended seal life, and the specially formulated Hi-Pressure Seals or V-Packings offer unmatched performance and seal life. A die cast aluminum crankcase provides high strength, minimum weight and precision tolerance control.
