MAINTENANCE/REPAIR INSTRUCTIONS
WARNING - DISCONNECT PUMP POWER CORD PRIOR TO WORKING ON
THE PUMP OR PERFORMING ROUTINE MAINTENANCE.
1.
Close gate valves to keep water from back-flowing into pump. Disconnect
piping from intake and discharge ports on pump.
2.
Remove bolts from the volute housing and then remove volute housing.
Inspect the volute housing, O-ring, and impeller.
3.
Remove the impeller from the motor shaft by turning the impeller counter-
clockwise. Remove small end cap on other end of motor and use a standard
screwdriver on the motor shaft to keep the shaft from rotating.
4.
The OPWG-29 and OPWG-46 pumps are equipped with a metal washer
behind the impeller. If replacing the washer, compare the thickness of the
existing washer with the two new washers (provided with the new impeller)
and use the one of the same thickness.
5.
Remove 4 bolts that attach the bracket to the motor. Do not insert screwdriver
tip into motor to pry against fan blades for it will damage the fan.
6.
REPLACING CERAMIC IMPELLER SEAL: Go through steps 1-3. Remove
the damaged seal from the impeller. Be sure to clean out any excess debris
in the bore where the old seal was removed. Apply a little water to rubber
seal component and with a lint-free cloth push the seal assembly into the
impeller bore. Note: Ceramic component must be inserted into rubber boot
prior to inserting into impeller seal bore.
7.
REPLACING THE MECHANICAL SHAFT SEAL/BRACKET: Go through
steps 1-4. Apply sealant to the bracket bore ID wall and around the outer
diameter of the seal case. Note: Prior to inserting seal into bracket bore,
place a small chamfer on the bracket bore. This will make the insertion of
the seal easier. DO NOT TOUCH OR APPLY PRESSURE TO THE CARBON
GRAPHITE SEAL FACE. Install new bracket containing mechanical seal.
Make sure the face of the carbon seal is free of any debris and be careful
Water level
not to damage the face of the seal in the process of re-assembling the
components. Note: If replacing the carbon graphite seal it is recommended
to replace the ceramic seal in the impeller.
8.
IF REPLACING THE SLINGER WASHER: Go through steps 1-4. Remove
damaged slinger washer from the motor shaft. Install the new slinger on the
shaft. Be sure that the new slinger washer is positioned over the step in the
motor shaft. This will keep the washer from sliding along the shaft when the
motor is operating.
9.
Attach bracket to motor, install 4 bolts, and tighten.
10.
Thread impeller onto shaft and tighten (turn the impeller clock-wise to tighten).
Remove motor end-cap and use a screwdriver on the back of motor shaft to
prevent shaft rotation while tightening. Replace motor end cap.
11.
Place O-ring back in the designated groove in the volute and install volute.
Be sure that the O-ring remains in the groove while attaching volute to the
bracket. Install the volute bolts, apply washers and nuts and tighten.
12.
Before making connections to the pump check to make sure the impeller
rotates CCW (impeller should turn the same direction as the arrow located
on the face of the volute). Incorrect rotation will damage the pump and void
the warranty! Reinstall pump.
