Transformer Oil Pumps for Fixed and Traction Applications
SPP's transformer oil pump range is designed and manufactured to the highest quality standards. SPP have been producing transformer oil pumps for more than sixty years. Life expectancy in many cases has exceeded forty years. Applications include oil circulation in the following:- power transmission, distribution and electric traction locomotive transformers.
Weatherproof - they can be installed in the open without any protective covering, all moving parts being completely enclosed and sealed.
No gland leakage - the pump and driving motor are built as a unit on a common shaft. The transformer oil circulates through the windings so that no shaft seal is required, thus eliminating completely the dangers of oil leakage or entry of air.
Easily mounted and coupled - with four alternative branch positions for either vertical or horizontal mounting, the pumps can easily be accommodated in a variety of cooling pipework arrangements.
Robust construction - the pumps are robustly build and the glandless construction enables the impeller to be fixed close to the shaft bearing.
Rotation - a window is fitted in the shaft end to enable direction of rotation to be observed.
No lubrication - the heavy duty ball and roller bearings carrying the robust shaft are lubricated by internal circulation of the transformer oil.
