Patterson Pro-Max® 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, and their back pullout configuration provides easy access for maintenance without disturbing piping connections. 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 sealant 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.
