c) Install the stationary seal into the housing hub with the smaller face entering the hub first.
For the Silicon Carbide Stationary Seal design
(
Figures 18 and 21
) - install the front half of the
stationary seal into the housing hub with the smaller face side first. Then install the rear half of the
stationary seal.
d) Install the stationary seal o-ring (do
not
lubricate this o-ring) onto the back of the stationary seal.
Improper fit may cause leakage or seal damage.
e) Place the retaining ring on the housing hub, aligning the holes in the retaining ring with the holes
in the hub.
f) Thread the four retaining ring bolts through the holes in the stationary seal retaining ring and into
the housing hub. Alternately tighten the bolts so the retaining ring secures evenly. Uneven tighten-
ing could result in seal damage. Check for proper torque on page
5.
g) SINGLE FLANGE: Carefully slide the pump housing over
the pump shaft and back against the flange support.
The
stationary seal may be damaged if it makes hard con-
tact with the pump shaft.
If the pump housing does
not slide into the flange support easily, widen the
flange support by driving a screwdriver into the slot
on top (
Figure 13
). Slide the pump housing all the
way into the flange support until the shoulder of
the housing is against the flange support. Remove
the screwdriver. If the pump has a double mechani-
cal seal or water cascade option, make sure that the
water pipe holes in the pump housing are aligned with
the holes in the flange support. While holding the pump
housing against the flange support, tighten the clamping bolt
in the flange support.
DOUBLE FLANGE: Carefully slide the pump housing (10) over the pump shaft (7) and back against
the flange support (2).
Note: the stationary seal may be damaged if it makes hard contact with the
pump shaft.
Install the housing bolts (29) and washers (30). Tighten to the proper torque listed on
page 4. Install the seal water pipe (if supplied), by threading it into the housing and tighten with a
pair of pliers. Align the discharge piping with the discharge outlet.
h) Install the seal water pipes (for double mechanical seals
or water cascade option), by threading them into the
housing and tighten with the pliers.
i) You are now ready to install the rotating seal assembly.
First lubricate the seal o-ring with a food grade lubri-
cant (unless the o-ring material is EPDM, then only wa-
ter should be used for lubrication). Place the seal o-ring
inside the rotating seal.
j) Now place the seal washer into the rotating seal.
k) Next install the one end of the seal spring into the rotat-
ing seal making sure that the tab of the spring is in the
slot on the rotating seal. (
Note:
for frame sizes 254 and
up, the larger end of the seal spring goes into the rotating seal
Figure 14
)
l) Finally, install the tab on the other end of the seal spring into the hole on the front seal driver
(
Figure 14
). The rotating seal assembly is now ready to be installed onto the pump shaft. (Note: for
pumps with a 735 seal, the larger end of the seal spring goes into the rotating seal.)
