CAT Pumps 901400 Complete Stainless Steel Head Assembly
Product Description
The CAT Pumps 901400 is a complete, block-style head assembly designed for the CAT Pump Model 3831 (38 Frame Block-Style Plunger Pump). This genuine replacement part is constructed entirely from 316 Stainless Steel, providing superior corrosion resistance and durability, making it ideal for aggressive fluids, high-purity water, reverse osmosis (RO) systems, and saltwater applications.
As a complete assembly, the 901400 includes the triplex manifold, valve assemblies (seats, valves, springs, and retainers), and the necessary seals and O-rings, configured for standard fluid compatibility (typically NBR/Buna-N). Installing this assembly restores the pump to its original performance specifications, supporting flow rates up to 36 GPM and operating pressures up to 1,200 PSI.
