Morrison Pump Company is a Business Unit of Patterson Pump Company, a global leader of quality pumps in the Fire, Municipal, Industrial, Flood Control, Plumbing and HVAC markets. We are proud to be a part of Patterson and the Gorman-Rupp Family of Pump Companies, with a long reputation of quality and reliability in pumping technology. Morrison specializes in the engineering design and state of the art manufacture of high capacity water pumps. Our pumps are the leading water pumps used in flood control, stormwater pumping, water and wastewater treatment, aquaculture, irrigation and drainage, environmental water management, and much more. Morrison Axial Flow and Mixed Flow Pumps offer a wide range of hydraulic coverage and are known for their high efficiency, durability and longevity.

The Axial Flow Pump generates it’s head exclusively through axial forces, and can be defined as pump impeller design with specific speeds greater than 10,000 (US Units). The axial flow impeller or lift coefficients and impeller total head. Standard Morrison Axial Flow Pump models have complete hydraulic coverage between approximately 4,000 GPM and 250,000 GPM capacities, with total heads to 30 feet.

The Mixed Flow Pump, or Combined Flow Pump generates it’s head through a combination of both axial and radial forces, and can be defined as pump impeller design with specific speeds between 4,200 and 9,000 (US Units). The Mixed Flow impeller inlet diameter differs from the discharge diameter with varying vane angles and radial velocities. Standard Morrison Mixed Flow Pump models have hydraulic coverage between approx. 2,000 GPM and 250,000 GPM capacities, with total heads between 25 and 75 feet of water.
