Instructions for mounting a lip seal

➢

First read the following instructions regarding the mounting of a lip seal. Follow these
instructions closely when mounting a lip seal.

• A lip seal is a fragile precision instrument. Leave the seal in its original packing until

you are ready to fit it!

• Clean all receiving parts properly.

• Make sure your hands and working environment are clean!

7.8.6

Assembly of the lip seals M4

1 Check the shaft sleeves (1900 and 1920) and the splash ring (2220) for damages.

Also, the splash ring should clasp the shaft properly. If necessary, replace these parts.

2 Place the bearing bracket with the shaft upright.

3 Mount the gasket (1950) around the pump shaft.

4 Slide the cover of the pump wheel casing (1510) onto the pump shaft.

5 Mount a lip seal on both ends of the shaft sleeve. The pointing direction of the tab

should be opposite to the sliding direction. Shaft sleeve (1900) will have 2 lip seals,
shaft sleeve (1920) will have 3.

When being mounted, the lip seals and the

space between them both must be filled with grease.

6 Slide the shaft sleeve (1920) onto the pump shaft.

7 Mount the key (1890) in the pump shaft and slide the pump wheel casing (1500)

onto the pump shaft.

8 Mount the pump cover (0110) in the right position in the fitting edge of the bearing

bracket. Check the position of the pump cover. It should be at right angles to the
pump shaft.

9 Mount the gasket (1361) between the pump cover and the pump wheel casing.

10 Mount the cover of the pump wheel casing (1510) against the pump cover. Watch

the position in view of the place for the connections. Tighten the Allen screws (1880)
crosswise. The cover should not be oblique.

11 Mount the O-ring (1905) into the shaft sleeve (1900) and slide the shaft sleeve onto

the pump shaft.

12 Fit the impeller and the other parts, see paragraph 7.7.2 "Mounting the impeller".
