MAINTENANCE

5. Check the rotor for wear or damage and replace
the rotor if necessary. Also refer to the
maintenance diagram in §
8.2 .
6. Place back the cover and fasten the retaining
bolts to the correct torque. Refer to §
11.1.6 .
7. Switch on the electrical supply to the pump.
8.5.3 Fitting the pump hose
1. Clean the (new) pump hose on the outside and
fully lubricate the outside with Bredel Genuine
Hose Lubricant.
2. Fit the pump hose (A) via one of the ports.
3. Run the motor so that the rotor pulls the hose
into the pump housing. Stop the motor when the
hose sticks out equally from both sides of the
pump housing.
CAUTION
When the rotor is worn the compression
force of the hose decreases. If the
compression force is too low, this results in
a loss of capacity because of the backflow
of the liquid to be pumped.
Backflow results in a reduction of the life of
the pump hose.
A
WARNING
During jogging the drive:
-
Do not stand in front of the pump
ports.
- Do not try to guide the hose by
hand.
