1051D Cat Pump 10 GPM 2200 PSI

Cat Pumps 1051D Duplex Stainless Steel Triplex Plunger Pump (10 GPM, 2200 PSI)

The Cat Pumps 1051D is an industrial-duty, 15-frame triplex plunger pump engineered specifically for rigorous, high-pressure fluid transfer in highly corrosive environments. Recognizing the severe demands of specialized industrial applications, this positive displacement pump features a heavy-duty manifold forged entirely from Duplex Stainless Steel. This premium metallurgy provides exceptional strength and extraordinary corrosion resistance, making it an ideal choice for continuous-duty seawater desalination, reverse osmosis (SWRO) systems, deionized (DI) water handling, and demanding chemical processing operations where standard materials would quickly fail.

Designed to maximize uptime and operational efficiency, this reciprocating plunger pump boasts a robust belt-driven configuration that allows for precision flow settings. Operating at a standard 958 RPM, it yields a highly consistent nominal flow rate of 10.0 gallons per minute (GPM) while safely accommodating a rigorous applied pressure of 2200 PSI. Inside the fluid end, the pump utilizes 316 Stainless Steel valve assemblies combined with advanced, concentric solid ceramic plungers. These plungers provide a true, low-friction wear surface, significantly extending the lifespan of the standard NBR (Buna-N) seals to ensure reliable, leak-proof operation. Whether integrated into an offshore marine watermaker or a specialized high-pressure sanitary system, the 1051D provides the steadfast hydraulic performance required for mission-critical liquid handling.
