its place unobstructed.
Let the parts cool down.
Lubricate the surface of the shaft where the rubber bellows rest
(figure 14, point A).
Figure 14. Installing the mechanical seal
The rubber bellows will not move on the shaft surface if it is not
lubricated.
CAUTION!
Only special lubricating gel that vaporises
between the rubber and shaft may be used for the
lubrication.
If the lubricant used for the rubber bellows
contains oil, the bellows might rub against the
shaft surface and thereby cause insufficient
sealing.
If the gel is not available, the bellows may be
lubricated with a small amount of water.
The rubber bellows is pressed tightly against the support ring.
Push the rotating part of the mechanical seal (figure 9, points C, D,
and E) into place against the support ring.
