CAT Pumps 237 Triplex Plunger Pump

The CAT Pumps 237 is a high-performance 3-Frame Triplex Plunger Pump engineered for continuous-duty liquid transfer and cleaning applications. Constructed with a highly durable Forged Brass manifold and solid ceramic plungers, this positive displacement pump provides exceptional longevity and wear resistance. Because of its robust design and ability to handle consistent, heavy-duty workloads, this model is widely utilized and highly recommended for commercial pressure washing systems, multi-bay car washes, and rigorous high-pressure cleaning networks.

Operating at an efficient 1125 RPM, the 237 delivers a steady, low-pulsation flow rate of 4.0 GPM at 1200 PSI. It comes factory-equipped with standard NBR (Buna-N) seals and O-rings, which allow it to safely process liquid temperatures up to 160°F (71°C). The pump features easily accessible valve assemblies and seals, ensuring that routine maintenance for your pressure washing equipment can be performed quickly and efficiently without removing the pump from its mounting.
