Transformer Oil Pumps

The pump and driving motor are assembled as a single unit on a common shaft. The transformer Oil circulates through the windings thus eliminating cooling fan, shaft seal and avoiding the danger of oil leakage or emtry of air.

The complete unit is weather proof and can be arranged for horizontal or vertical mounting. Lubrication of the bearings and cooling of the motor windings is achieved with the circulated transformer oil. This results in a very efficient rate of cooling of the motor windings with minimum re-circulation losses and maximum utilization of available motor power.
