Axial and Mixed Flow Pumps

Patterson Axial and Mixed Flow Pumps consist of a bowl assembly, outer column and discharge elbow, shaft and shaft cover tube, floor plate and motor mounting stand. The axial flow propeller or mixed flow impeller is positioned in its individual housing just above the suction bell and close to the pump inlet. Water enters the pump through the suction bell, is discharged by the impeller into a guide vane section or diffuser, and then is pumped through the outer column to the discharge connection of the pump elbow.

The pumps may be built in one or more stages, depending on the total head requirements. Axial and mixed flow pumps generally operate in a submerged state with suction entrances flooded. Horizontal units are installed with a positive suction head.
