SERVICE INSTRUCTIONS
NOTE: The seal consists of two parts. The half with the
metal case and carbon face go into the pump body. The
other half of the seal is a ceramic disk with a rubber boot
and is installed into the back face of the impeller.
Disassembly
1. Remove end cover screws, end cover and gasket.
2. Remove pipe plug in top of body and rotate impeller
so the set screw aligns with the plug hole. Insert a
1/8” allen wrench through the plug hole and loosen
impeller setscrew. Remove the impeller.
3. Remove screws securing the body to the motor and
remove the body.
4. Remove the old ceramic half of the seal with a screw-
driver or hooked wire.
5. From the motor side of the body press the metal case
seal half out of the body into the impeller bore. Clean
the seal bore.
Assembly
1. For the best results, apply a thin coat of pipe thread
sealant to the seal bore in the body before installing
new seal. Install the the seal from inside the body
using a hollow tube 1 1/4” OD by 1 1/8” ID. With the
tube against the flange of the seal press or tap gently
on the tube until the flange of the seal is seated all the
way around on the ledge in the body. Lubricate the
rubber boot with a small amount of soapy water. To
protect the seal surface put a clean piece of paper on
the ceramic face and push the seal by hand into the
impeller bore until it is completely seated. Be sure
that both the carbon and the ceramic faces are clean
of grease and fingerprints.
2. Install the body to the motor. Position the motor with
the pump body up and the back of the motor down to
correctly position the shaft end play.
3. Slide the impeller on the shaft with the set screw fac-
ing the plug hole in the body. Press the impeller down
compressing a spring in the seal until the impeller bot-
toms out against the body. Tighten the set screw in
the impeller before releasing pressure against the
impeller. This sets the proper seal face clearance.
4. Install the pipe plug into the body.
5. Ensure the body and end cover surfaces are clean
where they contact the gasket. Align the end cover
and new gasket with the body and secure it with the
end cover screws.
