Do not wet clean, only use a damp cloth. For stubborn soiling with chemicals, nutrient solution, etc.
immediate cleaning is necessary so that no difficult to remove encrustations form. Regular lubrication of the
transport roller bearings with silicon oil increases the service life of the rotor and tube significantly!
8.2 Disinfection
In case of biological contaminations, the outer surfaces of the pump and the individual parts of the pumping
head can be decontaminated by wiping down with a mild disinfectant.
Contact manufacturer to clarify whether the intended method causes damage or not before using a cleaning
agent or disinfectant other than those named.
9. Dismantling the pump head
To dismantle, proceed as follows:
1. Remove tube cartridge
4
and tube
7
2. Undo manual nuts
10
3. Pull off front plate
15
4. Pull off roller rotor
5
and thrust bearings
11
from the stud bolts
9
.
Now only the main body of the pump
14
remains with the bearings and drive shaft
12
on the housing and
can be cleaned as described above under „outside cleaning“. If this is not sufficient, the main body can be
removed by loosening the 3-crosshead screws and then cleaned.
Rinse off all removable parts with tap water, if necessary with cleaning additives, dry off and reassemble in
the reverse order.
Attention!
Place the roller rotor 5 on the drive shaft so that the driving pin 13 sits in the groove on the rear of
the roller rotor 5.
Occasional cleaning as described above is urgently recommended after extended use. Adhesion of talcum
residue caused by abrasion of the feed tube and other contamination of the pump head parts, especially on
the transport rollers should be removed regularly.
The tube clamping jaws
8
for holding the tube in the inlet and outlet of the pump head should occasionally be
cleaned with alcohol before starting to remove grease, splashed medium or other residues as required, to
ensure secure, slip free tube clamping.
9.1 Turning the pump head
After loosening the 3-crosshead screws of the pump head attachment (see above), the pump head, rotated
by 90°, can be affixed.
10. Malfunctions
The most frequent cause of malfunctions is setting the tube pressure too high. This results in
Jumping of the tube in front of the discharge side clamping jaws,
Reduction or blocking of flow,
Premature wear of the tube and in the worst case tube break,
Overloading of the drive motor,
