Installation Information

Replacement of the pump housing requires disassembly of the EQ Series wet end and removal of the existing plumbing connections. Electrical power to the pump must be completely disconnected and locked out before servicing.

During installation, inspect the housing O-rings, diffuser, impeller, shaft seal, motor adapter, seal plate, mounting hardware, and flange connections for wear or damage. Replace damaged sealing components as necessary before placing the pump back into operation.
