External feeding pump

This pump is required if the following conditions are met:

  • Distance between transformer and oil treatment plant ≥ 20m
  • Oil level in the evacuated transformer/oil tank ≤ 1 m
  • Transformer/oil tank under vacuum ≤ 100 mbar

This pump is connected to the control cabinet of the system and controlled from there.

Note: If the transformer is exposed to a vacuum below 1 mbar during filling, a volumetric pump (e.g. gear pump) with pressure control must be used instead of the centrifugal pump.
