Patterson EnviroFlo™ ES Series pumps are available with standard flows to 2,500 gpm, and heads to 400 ft tdh, in close-coupled and frame-mounted versions.
They feature a high-efficiency design that minimizes energy consumption, impacting Green initiatives. To simplify maintenance without disturbing piping connections
or removing the motor, a back pullout configuration, including a sliding motor base, provides easy access to internal parts. Every pump is hydrostatically
pressure-tested before shipment.
These pumps are engineered to last, with annular-pressure-reducing clearance and impeller balance holes to reduce axial thrust. Other long-life features include
grease-lubricated bearings and a fitted bronze shaft sleeve and seal that protects the shaft.
Gauge taps at the suction and discharge connections allow for easy operational status monitoring. The bearing housing mounts directly to the pump volute to save
space and provide proper alignment. Options include 250-lb discharge flanges, seal flush lines, a stainless steel shaft and stainless steel shaft sleeve.
