Installation, Operating and Maintenance Instructions (Original Instructions)
ABS submersible sewage pump XFP 80C - 201G
9.8
Bearings and Mechanical Seals
XFP pumps are fi tted with lubricated-for-life ball bearings. Shaft sealing is by means of double mechanical
seals.
ATTENTION!
Once removed, bearings and seals must not be re-used, and must be replaced in
an approved workshop with genuine ABS spare parts.
9.9
Changing the power cable (PE1 & PE2)
To facilitate quick and easy changing or repair of the power cable, the connection between the cable and motor
is by means of an integrated 10-pole terminal block.
To be carried out only by a qualifi ed person, in strict adherence to relevant safety regulations.
9.10 Cleaning
If the pump is used for transportable applications, then in order to avoid deposits of dirt and encrustation it
should be cleaned after each usage by pumping clear water. In the case of fi xed installation, we recommend
that the functioning of the automatic level control system be checked regularly. By switching the selection switch
(switch setting “HAND”) the sump will be emptied. If deposits of dirt are visible on the fl oats then these should
be cleaned. After cleaning, the pump should be rinsed out with clear water and a number of automatic pumping
cycles carried out.
9.11
Venting of the volute
After lowering the pump into a sump full of water, an air lock may occur in the volute and cause pumping
problems. To clear the air lock, raise the pump in the medium and then lower it again. If necessary, repeat this
venting procedure.
We strongly recommend that dry-installed XFP pumps are vented back into the sump by means of the (drilled
and tapped) hole provided in the volute.
