NE Pumps.
Cleaning.
If the pump is used for portable applications, pump clean water
through it after each use to prevent deposits of dirt and scale from
forming.
Impeller replacement.
In cleaning out the body (1), replacing the impeller (4), or replacing
the wear ring (on NE 6 pumps), disconnect the power, remove any
hex screws (13), and then lift the vertical motor and seal out of the
body. If necessary clean the body. Clean and examine the impeller
(4) for any pitting or wearing and replace as necessary. Inspect the
gasket (7) for any cuts or damage and replace as necessary. If the
impeller needs to be replaced remove the screw (33) and washer. As
the impeller is keyed onto the shaft with a square key (#), the impeller
should be pulled straight off the shaft using a wheel puller as
necessary. In the NE 6 pump, if the wear ring needs to be replaced
simply cut the ring (29) and remove being careful not to damage the
body (1).
