flushed with clean water. Rinse the pump parts in
water after dismantling.
Check the pump and replace the oil once a year. If
the pump is used for pumping liquids containing

pump must be checked at shorter intervals.
In the case of long operating time or continuous

7.2 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 you request Grundfos to service the pump, contact
Grundfos with details about the pumped liquid, etc.
before you return the pump 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.
