Maintenance and cleaning

Drive unit:The drive unit is maintenance-free but not immune
from wear. The carbon brushes of the motor wear down over time
and produce grooves in the collector. To clean the drive use only
water with a detergent that contains tensides, or use isopropylal-
cohol for stubborn soiling.
Dispersion tools:
be constantly monitored. In the event of leakage, the suction
effect of the rotating shaft can cause the medium to penetrate as
far as the drive unit. If liquid emerges from the side holes at the
top of the shaft tube, stop work immediately and check the seals.
The function of the dispersion heads depends on the condition of
the sharp edges on the rotor and stator. These edges may be
blunted very quickly in abrasive media, reducing the effectiveness
of dispersion.
The dispersion tool is cleaned by operating it is in a solvent which
dissolves substance residues and is not harmful to the seal.
Because of the high flow speed, this is usually sufficient to clean
the rotor and stator. The dispersion tool must be removed and cle-
aned immediately after use to prevent residues from adhering to
the threads of the rotor and stator and to prevent the formation of
undesirable bacteria cultures.
The dispersion tools may also be sterilized. The following methods
may be used:
A) Chemical methods:
alcohol, etc.) are good general-purpose disinfectants. It is
important that all disinfectant residues are then removed with
sterilized water..
rings and shaft sealing rings are resistant to solvents.
B) Sterilization with moist heat. This denotes the use of a steam
jet pressurized to 2 bar at 120 °C.
C) Sterilization with hot air. Hot-air sterilization is usually perfor-
med at 160 °C or 190 °C. (30 min)
