LF 401 PUMP ASSEMBLY AND SEAL INSTALLATION
When replacing the seal assembly lubricate all o-rings with food grade lu-
bricant to ease assembly. Once the pump is fully assembled turn the stub shaft a
few revolutions by hand making sure it turns relatively freely and nothing is rub-
bing inside the pump. Running the pump with foreign objects in the pump or hav-
ing the impeller making contact with either the cover or the casing will result in
serious damage if not completely destroying the pump. For assembling pumps
with single seals, start at step number #.
TOOLS REQUIRED FOR ASSEMBLY AND SEAL INSTALLATION:
1-1/4” socket wrench
Torque wrench
3/8” round bar
7/16” wrench

seal in this order one component at
a time figure 28.
2. Slots in the double seal driver
and rotating double seal fit over the
driving pins on the stub shaft. See
figure 29.
