Installation, Operation, & Maintainance Guide
Style 60/62/65
To scribe the correct locations for the component seal setting length use the following procedure:
1
. Reassemble the pump, including the shaft sleeve, seal chamber cover, and impeller as shown in Figure 8 .
After adjusting the impeller, apply layout dye to the shaft (or shaft sleeve) at the face of the seal chamber,
and scribe a line in the dye showing the location of the chamber face as shown in
Figure 9 .
2 . Measure the distance from the stationary mating ring face to the seal chamber face. This can be
accomplished by simply measuring the distance from the top of the gland gasket to the mating ring as
seen in
Figure 10 . The future location of Line #2 is shown as a reference for the reader.
3
. Disassemble the pump and apply layout dye at the approximate location of the seal face. Measure the seal
face distance (L) from Line #1 and scribe Line #2 into the dye as shown in Figure 11 .
4
. From the seal face location, measure back along the shaft to the specified operating length (C) and scribe
a third line (Line #3, Figure 12 ).
SEAL INSTALLATION
Complete the layout and marking of the shaft for
installation as described earlier before beginning
installation. A complete assembly should resemble
Figure 13 .
1 . Remove the seal from its packaging and
inspect for damage to any components and
seal faces.
Grease, scratches, or nicks on the seal
faces may cause leakage.
2 . Ensure the shaft and seal housing have been
properly cleaned as described in the
preparation section.
3
. Evenly press the mating ring into the gland. Be
careful to keep the face clean and use a
suitable and compatible cleaning solvent if the
face gets smudged or dirty.
4 . Gently position the gland with installed mating
ring on the shaft facing, but clear of, the seal
chamber.
Be careful to not damage the mating ring
while setting the gland into position.
5 . Separate the drive hub, packing, and bellows
assembly by removing the cap screws from the
drive hub.
6 . Slide the bellows assembly along the shaft until
it is just past Line #2.
7 . Lightly lubricate the shaft packing with a
suitable and compatible lubricant. Slide the
drive hub and packing on the shaft in the
proper orientation facing the end of the bellows
assembly (
Figure 14 ).
8 . Position the back of the drive hub to line up
with the setting length scribe line (Line #3).
9 . Fix the drive hub in position by alternately
tightening the provided cup point set screws to
the recommended torque values in the table
below (
Figure 15 ).
10 . Bring the packing and bellows assembly back
to the drive hub. Use the socket head cap
screws to draw in and compress the packing
until the specified 0.050 in. setting gap is
achieved (
Figure 16 ).
11 . Ensure the seal faces are clean and dry using
a suitable and compatible cleaning solvent for
the face material and elastomers.
12 . Reassemble the pump according to OEM
specifications.
13 . Bring the gland with the mating ring installed
into position and make sure that it mounts
concentric to the shaft.
