Patterson is a worthy contender in the HVAC field, with a full line of rugged Pro-Max® horizontal split case, end suction and vertical in-line pumps, packaged systems and system accessories specifically designed for performance and reliability. Across our pump line, you’ll find numerous engineering refinements.

High-efficiency design minimizes energy consumption. The back pullout configuration provides easy access and maintenance (end suction and in-line only). Gauge taps at the suction and discharge connections make possible complete monitoring flexibility. Annular pressure-reducing clearance, along with impeller balance holes, reduce axial thrust. A precision cast, dynamically balanced impeller minimizes vibration and maximizes bearing life. Precision bearings and machining limit shaft deflection to only 0.002 in. at the seal face. Bearing housings that mount directly to the pump volute save space and provide proper alignment.
