Check The Pump Body

Check The Pump Body

Don't forget to check the pump body for both wear and debris. Run your finger around the inside to feel for groves or rough spots and give it a good visual inspection.

Once you have done this apply some impeller lube to your finger and lube up the inside surfaces of the pump body including the back wall as it is part of the impellers sealing surface and the impeller spins on it as it does the front cover. Both the rear of the pump and the cover plate should be lubed before final assembly or insertion of the impeller.
