REVISION:
PUMP IS RUNNING WITH REDUCED FLOW
This can be caused by either pump and / or system related problems.
Check your system set-up:
Verify that all piping connections are tight and that there are no leaks in the
discharge line.
Check that any valves are fully open and operable and the discharge line and
valves are not clogged.
Check your system-head requirement. The pump flow will reduce if the point
of discharge has been raised or additional piping has been added.
Check your pump:
Verify proper direction of rotation.
Check the pump intake area to ensure that the impeller, strainer and mixer or
shredder is not clogged.
Visually inspect the wet-end components for wear. The performance of the
pump can be significantly reduced if casing and impeller have experienced
excessive wear. Check the impeller running clearance and adjust if required.
Replace parts as required.
