Protected against direct sunlight and heat
5. Protected against dirt and dust
6. Protected against freezing
7. Protected against vermin
If the motors have been supplied filled with a drinking water/antifreeze mixture,
store them in this filled condition.
Store unfilled motors in unfilled condition.
If previously unfilled motors have been filled for functional testing, for example, the
motor fill for storage must be equivalent to the drinking water/antifreeze mixture
used by KSB to provide protection up to -15 °C.
NOTE
As the antifreeze concentration gradually decreases over time the remaining
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 which have been removed from a system
Pump sets / motors which have been operated must generally be overhauled by
qualified specialist personnel, for example a service workshop authorised by KSB.
After the pump set / motor has been overhauled, fill the motor with drinking water /
antifreeze mixture providing protection up 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 the pump set / motor as described in this manual.(⇨ Section 7.5.1 Page 49
)
7.6 Reassembling the pump set
7.6.1 Mounting the motor
CAUTION
Pump set tipping over or slipping out of the suspension arrangement
Personal injury and damage to property!
▷ Always make sure pump sets in upright position cannot tip over.
NOTE
The submersible borehole pumps are supplied with a sealed sleeve coupling which
protects the motor shaft from contact with the fluid handled. If motors are supplied
without a pump, a sealed sleeve coupling must be used for mounting the pump on
the motor. Make sure this protection is ensured also when the pump is serviced
(dismantled) or replaced. Exception: No sealed sleeve coupling is required for type
series T. The motor shaft end is made of CrNi steel.
✓ Lifting equipment of sufficient load-carrying capacity is available.(⇨ Section 5.2.6
Page 25)
✓ A mounting flange or mounting guide hoop and lifting straps are provided.
✓ Loctite 242 has been prepared.
✓ The cleaning agent (e.g. Aceton made by Rhinix or similar) has been prepared.
✓ Grease (e.g. BIO-Chem Tech) is available.
✓ A torque wrench is on hand.
✓ Common assembly tools are on hand.
✓ The general assembly drawings are on hand.
