Patterson EnviroFlo™ ES Series Pumps

PRODUCT DESCRIPTION

Patterson EnviroFlo™ ES Series pumps bring over a century of hydronic pumping expertise to HVAC applications, delivering the rugged reliability and engineering refinements you expect from Patterson along with sustainable, energy-efficient performance. Available in close-coupled and frame-mounted configurations, these pumps feature a high-efficiency design that minimizes energy consumption, aligning with Green initiatives.

The back pullout configuration, including a sliding motor base, simplifies maintenance without disturbing piping connections or removing the motor, providing easy access to internal parts. Every pump undergoes hydrostatic pressure testing before shipment, ensuring optimal performance. With annular-pressure-reducing clearance, impeller balance holes, grease-lubricated bearings, and a fitted bronze shaft sleeve and seal, EnviroFlo™ ES Series pumps are engineered for long-lasting operation.
