Bearings and Mechanical Seals
Piranha pumps are fitted with lubricated-for-life ball bearings.
Shaft sealing is by means of double mechanical seals (Piranha-PE), and mechanical seal / lip seal (Piranha-S).
ATTENTION!
Once removed, bearings and seals must not be re-used, and must be replaced in
an approved workshop with genuine ABS spare parts.

Maintenance of Lifting Stations in accordance with EN 1056�
It is recommended that the lifting station be inspected monthly and its function checked.
In accordance with EN regulations, the lifting station should be maintained by a qualified person at the following
intervals:
in commercial premises - every three months.
in apartment blocks - every six months.
in a single family home - once a year.
In addition we recommend that a maintenance contract be taken out with a qualified company.

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 fixed 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 floats 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�8
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.
