Installing the New Seal Assemblies:
1. Seal Rotating Assembly: Carbon Disk, Spring, Steel Collar, Rubber ring
a. Before installing the seal rotating assembly, apply water to the shaft sleeve.
b. Grasp the assembly with the carbon disk facing outward. Insert the impeller sleeve through the
steel collar side. Using a twisting motion, push until the steel collar touches the base of the
sleeve.
2. Seal Stationary Assembly: Ceramic Ring, Rubber Boot
a. Before installing the stationary assembly, apply water to the rubber boot’s ribbings.
b. Being careful not to damage the ceramic ring surface, press the seal assembly squarely into
the seal cavity of the volute.
Reinstalling the Volute (Casing) to the Motor:
1. Align the four bolts located at the rear of the motor, with the 4 volute legs. These bolts extend
through the entire length of the motor, into the legs of the volute.
2. Pre-tighten the four bolts. Make sure that the motor shaft is accurately located in the center of (not
touching) the ceramic ring.
3. When the motor shaft is properly located, tighten the four bolts to secure the volute in place.
Reinstalling the Impeller:
1. Hold the motor shaft from rotating as follows: At the rear of the motor, insert a wide blade
screwdriver in the shaft end slot, or use a needle nose “vise grip” or pliers to hold the shaft between
the motor face and impeller sleeve opening.
2. Thread the impeller clockwise over the motor shaft. Hand tighten only. Make sure the seal carbon
disk is in contact with ceramic ring. Caution: Do not grip impeller sleeve.
3. Reinstall the wear ring over the impeller hub in correct orientation.
Reinstalling the Suction Cover:
1. Inspect the o-ring for damage. Replace if necessary.
2. Properly install the o-ring on the cover before mounting the cover to the volute.
3. Cover can be mounted to the volute in one orientation only. An “aligning” feature is built-in with
each part, to ensure proper mounting. When properly aligned, the cover should slide in easily.
4. Secure the cover to the volute with screws. Tighten all screws alternately (crisscrossing the cover)
to achieve proper o-ring compression and cover seating.
5. Rotate the impeller by hand to make sure that it is rotating freely, without any interference.
Reconnecting the Pump Unit:
1. Clean the seals, gaskets, or o-rings of the plumbing connectors. Replace if cracked, worn, or
damaged.
2. Reconnect the plumbing lines to the pump. Hand tighten only.
3. Be sure that the pump unit is secured properly to the platform or base, if applicable. Tighten the
bolts if necessary.
4. Reconnect the power supply. Be sure that all wires are properly and securely connected.
To order replacement parts please contact your local authorized dealer.
