Cat Pumps 5CPQ6221 5-Frame Triplex Plunger Pump

 

The Cat Pumps 5CPQ6221 is an industrial-duty, 5-frame triplex positive displacement plunger pump engineered for high-pressure, continuous-duty liquid transfer. Constructed with a precision-machined 316 stainless steel manifold and 316 stainless steel valve assemblies, this specialized pump provides exceptional structural strength and superior corrosion resistance when handling demanding liquids. This model incorporates Cat Pumps' advanced "Q" noise-reduction engineering, which effectively lowers sound emissions to provide a smooth, quiet operation suitable for sensitive commercial environments. Its internal wet-end features highly polished, solid ceramic plungers that offer a true concentric wear surface to minimize friction and heat, significantly extending internal component life.

Designed for consistent performance and maximum efficiency, the 5CPQ6221 delivers a steady flow rate of 6.0 gallons per minute (GPM) while operating at a maximum pressure of 2,000 PSI. Driven at an optimal speed of 1400 RPM, it features a heavy-duty die-cast aluminum crankcase equipped with splash oil lubrication to ensure maximum load capacity and extended bearing life. This standard model comes factory-equipped with NBR (Buna-N) seals and O-rings, allowing it to safely handle liquid temperatures up to 160°F (71°C). Its compact, versatile footprint permits multiple drive options including belt, clutch, or direct-drive configurations, making it a highly reliable fluid handling solution for reverse osmosis (RO) systems, desalination, chemical injection, and critical industrial process applications.
