INSTALLING NEW SHAFT SEAL
Before handling
shaft seal parts,
wipe hands clean. Dirt or grease can
damage the seal.
1. Wet the inside of the seal cavity
on seal plate and the rubber cup
enclosing the new ceramic seat
with cooking oil. Be careful not to
scratch the ceramic surface of the
seal seat and 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.

2. Carefully slip seal plate over shaft
so as not to disturb seal position in
seal plate. The seal plate must be
orientated during assembly so that
the two holes are on a horizontal
line across the motor shaft (Figure
14). 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 15).
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 convertible
applications the seal ring must also
be positioned on the diffuser. 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
motor end cap should be secured before
operation.
