When installing the mechanical shaft seals, please be aware that these are precision products and that they should
be handled as such. The slide faces must be protected during the installation.
Push the stationary sealing ring into place. Be careful not to damage the slide face during the installation.
When the stationary part is mounted and straightened with a dial gauge, it is wiped off with degreaser.
The rotating sealing ring is put over the shaft. To ease the installation put soap water on the interior side of the
rubber bellows as well as on the shaft. Do not apply silicone, PTFE lubricants or oil as they will prevent the rubber
bellows from sticking to the shaft. Installation arbour should be used. The propeller hub keeps the outer mechanical
shaft seal in place. This happens when the propeller hub is tightened against the output shaft collar. At the inner
mechanical shaft seal the locking ring must be put on the shaft and the seal pressed together until the locking ring
snaps into the locking ring groove. Inspect the sealing by turning the motor shaft.
Test the mixer for leakage by submerging it and by putting the motor casing and the oil chamber under pressure.
The pressure is to be approx. 1 bar. Leakage (air bubbles) must not appear. Oil is filled into the oil chamber/gear.
During the filling the mixer must be in a horizontal position.
Repair of surface coating, if any, is necessary prior to operation start. See instruction for maintenance of surface
coating.
Oil quantity: see spare parts list.
