7CP6111CS Cat Pump 10.5 GPM 2000 PSI 7CP PUMP CS SS

Cat Pumps 7CP6111CS Stainless Steel Triplex Plunger Pump (10.5 GPM, 2000 PSI)

The Cat Pumps 7CP6111CS is an industrial-duty, 7-frame triplex positive displacement plunger pump engineered for continuous-duty, high-pressure liquid transfer and high-volume cleaning applications. Constructed with a precision-machined 316 stainless steel manifold and 316 stainless steel valve assemblies, this premium pump offers superior structural strength and excellent corrosion resistance in demanding commercial environments. Its internal wet-end components feature high-density, polished solid ceramic plungers that provide a true concentric wear surface. This advanced design minimizes friction and heat generation, ensuring significantly extended seal life and highly reliable operation even under rigorous, continuous duty cycles where standard brass components would prematurely degrade.

Designed for consistent performance and a smooth, low-pulsation flow, the 7CP6111CS delivers a robust flow rate of up to 10.5 gallons per minute (GPM) at a maximum operating pressure of 2,000 PSI. Driven at an optimal speed of 1750 RPM, it utilizes a heavy-duty die-cast aluminum crankcase equipped with a splash oil-bath design for maximum lubrication of the internal drive components. Its pre-set, low-pressure seals are efficiently lubricated and cooled by the pumped liquid, providing secondary protection against external leaks. Featuring standard 3/4" NPT(F) inlet and 1/2" NPT(F) discharge port configurations, it is highly versatile for multiple drive setups, including direct drive with a bell housing and flexible coupling, clutch, or standard belt drive. This durable, stainless steel construction makes it a proven, high-efficiency solution for demanding pressure washers, saltwater reverse osmosis (SWRO), chemical injection, and critical industrial fluid transfer processes.
