Information sticker / motor fill
Submersible motors are filled with a liquid based on drinking water.
A distinction is made between filled and unfilled motors, marked by a colour-coded
information sticker attached to the motor.
Motors which are supplied filled with a mixture of drinking water / antifreeze agent
must not be filled with pure drinking water at a later stage without prior
consultation with the manufacturer.
Sticker colour
Mixing ratio / purpose
▪ The motors must only be filled with an antifreeze agent on a 1,2 propylene
glycol basis which has been approved by KSB.
▪ The drinking water / antifreeze mixture supplied by the factory is intended for
operation as well as storage, transport and preservation. It protects the motor
down to temperatures of -15 °C. Permissible deviations see other applicable
documents.
▪ The percentage of antifreeze agent must always be selected for the expected
temperatures below 0 °C at the place of installation/transport/storage.
▪ The motor fill must be prepared with clean drinking water. The mixing ratio and
total quantity must be observed.
