9. Service
Before starting any work on a pump used in liquids which could
constitute a hazard to health, thorough cleaning/venting of the
pump, tank, etc. must be carried out according to local
regulations.
Damaged parts should always be replaced by new approved
parts. Motor parts must not be reconditioned by machining,
retapping, welding, etc.
9.1 Contaminated pump
If Grundfos is requested to service the pump, Grundfos must be
contacted with details about the pumped liquid, etc. before the
pump is returned for service. Otherwise Grundfos can refuse to
accept the pump for service.
Possible costs of returning the pump are paid by the customer.
However, any application for service (no matter to whom it may
be made) must include details about the pumped liquid if the
pump has been used for liquids which are injurious to health or
toxic.
Warning
Before starting work on the pump, make sure that
the fuses have been removed or the mains switch
has been switched to off. Make sure that the
power supply cannot be accidentally switched
on.
All rotating parts must have stopped moving.
Warning
All regulations applying to pumps installed in
potentially explosive environments must be
observed.
Make sure that no work is carried out in
potentially explosive atmosphere.
Warning
Explosion-proof pumps must be serviced and
repaired by Grundfos or a service partner
appointed by Grundfos.
Warning
If a pump has been used for a liquid which is
injurious to health or toxic, it will be classified as
contaminated.
