Figure 2. Seal Assembly
This seal is not designed for operation at
temperatures above 160
_F (71_C). Do not
use at higher operating temperatures.
NOTE
The white “Chemlon” stationary seat gasket must
be installed on the seal cavity side of the stationary
seat.
Assemble the stationary seat and gaskets in the
seal cap (20) and secure to them to the intermedi­
ate with the hardware (14 and 15).
Slide the assembled intermediate and stationary
portion of the seal over the shaft and secure the in­
termediate to the motor housing with the previous­
ly removed hardware (12 and 13).
New seal assemblies may be equipped
with spring holding clips for storage
purposes. Remove and discard these
clips before proceeding with seal reas­
sembly. When removing the clips, use
caution so that they do not pop off
abruptly and cause personal injury. Fail­
ure to remove these clips can result in
seal failure and pump damage.
A new seal assembly may be furnished with re­
straining clips which keep the wedge from being
compressed prior to assembly. Remove and dis­
card the seal spring restraining clips.
Lubricate the I.D. of the wedge and rotating ele­
ment with water or a very small amount of oil, and
slide the rotating portion of the seal assembly onto
the shaft until the seal faces contact.

To verify the impeller positioning, measure the
vane plate and impeller as shown in Figure 3. Use
