Assembly
6. Install the stationary seal assembly:
a. Install the stationary inboard gasket (P80R) into the bottom of the pump casing (X7) stationary seal cavity. Ensure that the
gasket is sitting flat and it centered properly by the slight counter bore in the bottom of the seal cavity.
b. Place the stationary seal (P80N) on top of the inboard stationary gasket (P80R).
c. Place the stationary outboard gasket (P80P) on top of the stationary seal.
d. Place the seal ring gland (X6) on top of the stationary outboard gasket (P80P) so that the part number on the seal ring gland
is facing up.
e. Apply liquid thread locker to the seal ring gland bolts (X6A) and thread the bolts through the seal ring gland and into the pump
casing (X7).
f. Tighten the seal ring gland bolts (X6A) in a star pattern according to the recommended torque value chart given in this
manual.
7. Attach the pump casing to the adapter:
a. Lower the pump casing (X7) onto the pump adapter (X2) compressing the rotating seal assembly as you lower the casing.
b. Press down on the casing (X7) making sure that casing is sitting firmly against the adapter (X2).
c. Thread the adapter-casing bolts (X2A) through the adapter slots and into the threaded holes on the back of the pump casing
(X7). Note: apply liquid thread locker to the bolts.
d. Thread the adapter-casing bolts (X2A) in until finger tight. Adjust the position of the casing by rotating until the desired
position is reached.
e. Tighten the adapter casing-bolts (X2A) evenly and torque to the value given in the recommended torque value chart given in
this manual.
8. Attach the impeller to the stub shaft:
a. Apply food grade lubricant to the impeller O-ring (X8A) and place the O-ring in the O-ring groove of the stub shaft (X4).
b. Thread the impeller (X8) onto the pump stub shaft (X4). Tighten the impeller until you feel it bottom out against the stub shaft
(X4). Note: place an Allen wrench in the leak detection hole on the base of the stub shaft (X4) to lock against the adapter (X2)
while tightening the impeller.
9. Install the front cover onto the casing:
a. Apply food grade lubricant to the front cover O-ring (X9A) and place the O-ring into the O-ring groove of the front cover (X9).
b. Place the front cover (X9) onto the pump casing (X7).
c. Install the front cover wing nuts (X10) onto the threaded casing studs. If the stud is damaged in any way, it can be replaced
with a standard cup point set screw (

-18 x 1¼ for all 100 series models and ⅜-16 x 1¼ for all 200 series models).
d. Tighten the front cover wing nuts (X10) evenly using a wrench on the flats of the wing nuts.
e. Rotate the pump stub shaft (X4) to ensure that you do not hear any metal to metal contact of the impeller with the front cover.
If there is contact, disassemble and recheck the setting of the stub shaft sleeve (X5).
10. Install the adapter guards:
a. Using the provided guard bolts, attached the two safety guards (X3) to the adapter (X2) and tighten securely.
