Product Overview

12 GPM Brass Manifold Piston Pump

The CAT Pumps 390 model is a positive displacement, reciprocating pump with a three piston rod triplex design. This five frame pump features a brass manifold, 304 stainless steel valve assemblies, chrome-plated 304 stainless steel cylinders, and standard Buna-N o-rings and seals.

The CAT Pumps 390 pump has a low RPM that is designed for belt drive applications. Its Uniflow design includes a mechanically actuated inlet valve that provides constant forward flow and strong suction. 1" NPTM x 1/2" NPTF ports are located on the side for easy plumbing. Maximum flow rate of 12 GPM and a maximum pressure rating of 600 PSI. Extreme durability and incredible abrasion resistance make this perfect for demanding environments like high-volume car washes and commercial pressure washing.
