Our HSC line for HVAC enables you to specify match your pump precisely to the duty at hand in flows to 5,000 gpm and heads to 175 ft tdh. Patterson HSC pumps are durable by design. A flex coupling absorbs vibration. The precision-cast, dynamically balanced bronze impeller minimizes vibration and maximizes bearing life. Bronze fitted construction with bronze shaft sleeves is standard. If you want higher hardness and less deflection than a standard carbon steel shaft provides, you can specify our stainless steel shaft option. The standard design has a 175-psi case working pressure; you can also move up to a 250-psi rating on all models.

Once installed, Patterson HSC pumps are designed to be easily maintained. The easily removed coupling aids serviceability. Shaft ball bearing sets, set in integrally cast bearing housings, are regreaseable.

Other features include gauge taps at the suction and discharge connections, an OSHA coupling guard and a Class 30 cast iron body. Every pump is hydrostatically pressure-tested before shipment.
