12.3 Contaminated pumps

If a pump has been used for a liquid which is
injurious to health or toxic, the pump will be
classified as contaminated.
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 to be 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.
Before a pump is returned, it must be cleaned in the best possible
way before it is returned.
