Patterson ENVIROFLO™ HYDRONIC PUMPING SOLUTIONS

PRODUCT DESCRIPTION

EnviroFlo™ Horizontal Split Case (HSC) HVAC pumps stand out for their reliable, energy-efficient performance in hydronic heating and cooling applications. With a design that prioritizes sustainability, these pumps not only minimize energy consumption but also provide precise matching to required duty points. This unique feature makes them the perfect choice for those seeking to integrate environmentally conscious HVAC systems.

Engineered for durability, EnviroFlo HSC pumps feature a flex coupling to absorb vibration, a precision cast, a dynamically balanced bronze impeller for reduced vibration and extended bearing life, and bronze-fitted construction with bronze shaft sleeves as standard. The pumps are built to last, with options for stainless steel shafts and higher case working pressures to meet specific application needs.

FEATURES AND BENEFITS

• High-efficiency design minimizes energy consumption for a more sustainable HVAC system.
• Precise pump matching to required duty points, with flows up to 6,000 GPM and heads to 160 ft
• Durable construction featuring flex coupling, precision-cast bronze impeller, and bronze shaft sleeves
• Optional stainless steel shaft for higher hardness and less deflection than standard carbon steel
• Choice of 175-psi or 250-psi case working pressure ratings on select models
• Easy maintainability with removable coupling, re-greaseable shaft ball bearing sets, and integrally cast bearing housings
• Gauge taps at suction and discharge connections for monitoring performance
• OSHA coupling guard and Class 30 cast iron body for enhanced safety and durability

APPLICATIONS

• Hydronic heating and cooling systems in commercial, institutional, and industrial buildings
