Cat Pumps 661D Plunger Pump

 

The Cat Pumps 661D is an industrial-grade, triplex positive displacement plunger pump engineered for high-flow and high-pressure performance in corrosive environments. Built with a specialized Duplex Stainless Steel manifold and high-strength internal components, this pump is designed to withstand the most demanding continuous-duty applications. It is a premier choice for desalination systems, seawater reverse osmosis, and high-pressure chemical injection where superior corrosion resistance and mechanical reliability are required.

Equipped with a reciprocating plunger design, the 661D provides a smooth, low-pulsation flow that protects downstream system components. Its 15-frame design features a chrome-moly crankshaft and oversized bearings, ensuring a long service life and minimal maintenance requirements in heavy-duty environments involving aggressive fluids or salt water. The construction allows for streamlined maintenance with accessible valve assemblies, making it a reliable workhorse for specialized industrial facilities.
