CAT Pumps 3550 Plunger Pump

The CAT Pumps 3550 is a heavy-duty Triplex Plunger Pump engineered for continuous-duty industrial applications. As a positive displacement pump, it provides a consistent and precise flow, ensuring maximum reliability in the most demanding high-pressure systems. This model is specifically rated for a flow rate of exactly 10 GPM, delivering the substantial water volume required for large-scale industrial tasks such as hydrostatic testing, water jetting, and heavy-duty pressure washing.

Constructed for extreme durability, the 3550 features a Chrome-Plated Brass block-style manifold and 304 Stainless Steel valve assemblies, providing exceptional structural strength and surface hardness for demanding fluid handling tasks. The pump utilizes high-density, polished solid ceramic plungers to create a smooth, long-lasting wear surface that significantly extends the life of the high-pressure seals. Its advanced triplex design minimizes pulsation and vibration, delivering the steady displacement required to maintain system integrity during 6,000 PSI operation.
