7.1 Service kits
Service kits are available for the MQ pump.
The service kits consist of the following replaceable
parts:
• shaft seal,
•motor,
• electronic units,
• hydraulic components.
7.2 Start-up after a long time of inactivity
The end cover incorporates a plug which can be
removed by means of a suitable tool. It is then
possible to free the pump rotor if it has seized up as
a result of inactivity. If the pump has been drained,
it must be filled with liquid before start-up. See fig. 9.
8. Service
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.
9. Disposal
This product or parts of it must be disposed of in an
environmentally sound way:
1. Use the public or private waste collection service.
2. If this is not possible, contact the nearest
Grundfos company or service workshop.
If a pump has been used for a liquid
which is injurious to health or toxic,
the pump will be classified as
contaminated.
