The high-efficiency design of our HSC line of EnviroFlo™ pumps minimizes energy consumption for a more Green sustainable HVAC system. Match your pump precisely to the duty at hand in flows to 6,000 gpm and heads to 160 ft tdh. EnviroFlo 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 select models. Once installed, EnviroFlo HSC pumps are designed for easy maintainability. The easily removable 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.
Applying more than a century of engineering expertise in hydronic pumping technology to HVAC applications, Enviroflo™ pumps offer the rugged, reliable service and engineering refinements you expect from Patterson along with sustainable, energy-efficient performance that addresses Green strategies.
