7 Servicing/Maintenance

7.5.1 Storing new submersible borehole pumps

For prolonged storage of pump sets / motors that have not been in operation
proceed as follows:
1. Remove the pump set / motor from its packaging.
2. Vertical (motor below)
3. In a dry environment
4. Protected against direct sunlight and heat
5. Protected against dirt and dust
6. Protected against freezing
7. Protected against vermin
Motors that are supplied filled are stored with the motor fill, i.e. a mixture of
drinking water / antifreeze agent.
Store unfilled motors in unfilled condition.
If motors that were supplied unfilled are then filled e.g. for a functional test, the
motor fill required for storage must correspond with that used for motors that are
supplied filled, i.e. a mixture of drinking water / antifreeze agent providing
protection down to -15 °C.
NOTE
Antifreeze concentration gradually decreases over time. Therefore, the antifreeze
level must be checked with a spindle. If the anticipated temperature is below the
antifreeze value, either increase the antifreeze concentration in the motor
accordingly or store the pump set in a frost-free location.

7.5.2 Storing submersible borehole pumps that have been removed from the system

Pump sets / motors which have been operated must be overhauled. This must be
performed by qualified specialist personnel, for example from a service workshop
authorised by KSB. After the pump set / motor has been overhauled, fill the motor
with drinking water/antifreeze mixture providing protection down to -15 °C, and
store it. Motors must only be stored in unfilled condition if, in addition to the above,
the inside of the motor has been preserved against corrosion. Store as described in
this manual. (ð Section 7.5.1, Page 75)
