INSTALLING NEW SHAFT SEAL
Before handling shaft seal parts wipe hands
clean. Dirt or grease MAY damage the seal.
Se laver les mains avant de manipuler les
pièces du joint de l'arbre. La poussière ou la graisse POURRAIT
endommager le joint.
1. Push seat enclosed in rubber into seal cavity on seal plate. Use
a cardboard washer to protect polished surface when pushing
against ceramic seat with any object. Be sure to remove
cardboard washer.
NOTE: Be careful not to scratch the ceramic surface of the seal
seat.
2. Carefully slip seal plate over shaft. Do not disturb seal position
in seal plate. The seal plate must be orientated during assembly
so the two screw holes are on a horizontal line across the
motor shaft (Figure 10). This placement should be done to
ensure proper draining and priming.
3. Place rotating shaft seal member in position on impeller and
press into place. Take care not to press against polished seal
surface.
4. Position impeller on shaft and tighten securely (Figure 11).
5. Secure diffuser to seal plate using the two cap screws. Be sure
the arrow on the front of the diffuser is pointing up and the
screws are orientated on a horizontal line as described in Step
2.
6. Carefully position pump housing (volute) gasket over the diffuser
onto the seal plate. In all shallow well applications care must
be taken that the o-ring is clean and properly positioned on the
venturi. Cleaning and positioning makes a good seal inside the
diffuser when assembled.
7. Assemble the pump housing (volute) to the motor using the
four cap screws. Be sure the pump housing (volute) gasket is
positioned correctly and tighten the screws securely.
NOTE: Shaft must rotate freely and rear cover should be secured
before operation.
