A.7.2.2 Disassembly of Rotor and Mechanical Seal
1. Remove small flange (232), O-Ring (401), and hex nut (233).
2. Pull rotor (230) from shaft. Use two screwdrivers to assist in prying the rotor from the shaft.
3. Remove rotating element of mechanical seal from rotor as well as the stationary seat and O-ring from
intermediate casing.
4. Remove 4 hex screws (901) from motor/casing connection and remove casing. Use a mallet to lightly
tap the casing to aid in its removal.
A.7.3 Re-assembling
Prior to re-assembling, eliminate any scale deposits, clean all parts, and inspect to ensure that they are in good
condition. Exercise care when cleaning not to damage any parts when using a scraper.
The procedure for re-assembling the pump is as follows:
NOTE: All of the following steps should be performed with the motor or bracket placed vertically.
1. Install mechanical seal O-ring and stationary seat into intermediate casing (109).
2. Lock intermediate casing (109) to motor or bracket flange using 4 hex screws (901).
3. Screw pin (800) to the motor shaft.
4. Place rotating portion of mechanical seal onto rotor hub.
5. Place rotor onto shaft.
6. Screw nut (233) to the rotor and tighten firmly.
7. Check axial clearances. See table No. 6 for the recommended clearances:
8. Place O-ring (401) into position and screw plug (232) firmly into place.
9. Replace and lock into place valve (435) and valve cover (360) using 2 hex screws (902).
10. Place a bead of liquid sealant on contact surfaces of the plate (137).
11. Tighten plate (137) to cover (109) using allen screw (872). Tapping plate lightly with a mallet will aid
in seating the plate.
12. Place a bead of liquid sealant on contact surface of the intermediate casing.
13. Place cover (109) onto intermediate casing and secure with 5 hex screws (905).
