Components of the bearing and impeller
mount tool. 1: handle and rod, 2: hair-pin-type lock, 3: bear-
ing mount tool, 4: impeller mount tool.
3.3. Use of the bearing / impeller installation tool (Op-
tion).
To change the impeller and male bearing in applications
where it is difficult to access the tank, a special
bearing and
impeller mount tool
can be used. It consists of the following
parts (see figure 3):
1. Handle
2. Hair-pin-type lock
3. Bearing mount tool
4. Impeller mount tool
To facilitate mounting of the male bearing it is recom-
mended to apply a small amount of suitable grease on
the PTFE washer. This prevents the PTFE washer from
loosening from the bearing unit during mounting.
The bearing and impeller mount tool are ordered sepa-
rately.
3.4. Mounting and dismounting the drive unit
The drive unit consists of a motor (either AC, DC or Air
driven), gearbox, flange and rotor (some differences occur
depending on type of drive and size).
Be certain that you can handle the weight of the drive
unit. Take a firm grip of the gearbox to balance the weight
of the drive unit and to minimize the risk of damage
caused by crushing when dismounting. Use appropri-
ate lifting device for the larger models, SM 120/190 and
larger.
3.4.1. Mounting the drive unit
There are two different ways of attaching the drive
unit to the flange of the vessel, depending on Sterim-
ixer/Sanimixer size, by a bayonet coupling or by a
threaded joint.
Ensure the magnetic rotor is not damaged and properly
aligned preventing physical contact with the weld plate
upon installation and operation.
60/75; 85/100 - 140; SMMS 85 - 120; Sanimixer 500
1. Lift up the drive unit and let the welding plate’s
screws pass through the slots in the drive unit
flange.
2. Turn the drive unit counter clockwise into posi-
tion.
3. Lock the drive unit in position by tightening the
locking nuts.
120/150 -190; SMMS 120; Sanimixer 3 000
1. Lift up the drive unit and let the welding plate’s
screws pass through the slots in the drive plate.
2. Turn the drive unit counter clockwise into posi-
tion.
3. Lock the drive unit in position by tightening the
locking nuts.
120H/220 ; 210/275-350; Sanimixer 7 000 - 30 000
1. Lift up the drive unit and let the flange screws
pass through the holes in the drive unit flange.
