Installation Information
Motor replacement requires disassembly of the EQ Series pump and proper connection to the existing pump wet end. Electrical power must be disconnected and locked out before servicing.
Because this is a three-phase motor, motor rotation must be verified after wiring. Incorrect rotation can result in reduced flow and improper pump operation.
Inspect the mechanical shaft seal, impeller, diffuser, O-rings, and associated hardware during motor replacement. Replacing worn sealing components at the same time is recommended.
Confirm Before Ordering
Verify the existing motor, pump model, horsepower, voltage, and phase before purchase.
