the pocket in the seal housing. Note, keep the
oil off the seal face. Without scratching the seal
face, press the ceramic stationary portion into
the seal housing with a Myers seal pusher. With
clean cloth, lightly wipe the face of the seal surface
to make sure it is dirt free. Remove the rotating
portion of the seal from the package and lubricate
the inside diameter of the rubber bellows and the
outside diameter of the shaft. Place the seal over
the shaft (make sure the key is removed). Evenly
press on the body of the rotational assembly and
slide it down the shaft until the seal faces meet.
Once the seal assembly is in position, place the
spring over the register on the rotational portion of
the seal.
2. Before placing impeller on shaft, the seal spring
retainer should be placed on shaft with stepped
end toward seal spring. Position the key into the
seat in the shaft. Align the impeller onto the shaft,
making sure that the seal spring is registered
properly onto the back side of the impeller. Insert
the bolt and washer assembly into the shaft and
tighten to 193 ft.-lbs. Replace the nose cone
onto the impeller. The proper Loctite
®
should be
applied to the bolts. Install and tighten.
3. Fill the seal chamber with new dielectric oil.
An air gap of 10-15% volume must be left for
the expansion of the oil when it is at operating
temperature.
4. The wear ring can be aligned with the retaining
holes and tapped into place with a soft mallet.
The proper Loctite should be applied to the bolts.
Install and tighten.
5. The motor and impeller assembly can be installed
into the volute. Make sure that the impeller aligns
properly with the volute. Install the volute retaining
bolts and tighten.
6. Air tends to trap in the pump case when water
rises in the sump or when the pump is lowered into
the water after service. To vent off this air, a small
hole is drilled into the volute casting.
Be sure
this vent hole is clean after any service work
on pump.
Air venting is not a problem after initial
start.
