Steel gears, cast iron housing and journal bearings give high efficiency and allow high speed operation, but journal bearing pumps should not be operated under heavy load at less than 600 RPM.
Pumps are designed for in-line direct drive. Please consult your nearest Womack office to see if pump should be de-rated for side drive.
