6.2 Assembly
Do not touch the seal faces of the stationary seal ring
(103) or rotating seal ring (104). Only hold these parts on
their sides.
Do not apply any kind of grease or lubricant on the
stationary seal ring (103) or rotating seal ring (104) since
this can result in malfunction of the shaft seal.
Handle all shaft seal parts very carefully and avoid
scratching or denting them.
1. Clean and de-grease all parts.
2. Lubricate the new O-ring (110) and install it in the shaft seal
cartridge (115).
3. Install the spring (108) on the shaft seal cartridge (115).
4. Install the upper seal driver (112a) on the shaft seal cartridge
(115).

(115).

seal-ring retainer (114).

(114).
9. Install a new stationary seal ring (103) in the stationary seal-ring
retainer (114).
10. Install the stationary seal-ring retainer (114) on the shaft seal

12. Install the lock ring (116) on the shaft seal cartridge (115).
13. Press down on top of the lock ring (116) while aligning the three
set screws (113) with the holes in the shaft seal cartridge (115).
14. Screw in the three set screws (113) only so much that they
engage with the holes in the shaft seal cartridge (115) and keep
the shaft seal parts together.
Note that the screws (113) must not protrude on the inside of the
shaft seal cartridge (115) since this will make it difficult to re-
install the shaft seal (105) on the pump shaft (51).
