Lubricated-for-life ball bearings together with monitoring devices ensure optimum pump reliability provided that
the pump has been connected and operated in accordance with the operating instructions.
Should, nevertheless, a malfunction occur, do not improvise but ask your Sulzer Customer Service department
for assistance.
This applies particularly if the pump is continually switched off by the current overload in the control panel or by
the alarm.

6.2 Piranha shredding system
The shredding system of the Piranha is a wearing part and as such may need to be replaced. A reduction in
cutting performance can reduce output. We recommend that the shredding system be inspected regularly. This
is particularly so if sewage containing sand is being pumped. Regular inspection and care is recommended to
ensure a long service life.
