Oil pump “1TT”

"1ТТ" type electric pump units - centrifugal, glandless wet-stator, single-stage pumps with the closed impel¬ler are designed to handle transformer oil with the temperature from 258 to 378 К (from-15 to + 105 °С) in the power transformer cooling systems of the stationary and mobile plants.
The pumps can be installed in horizontal and vertical position.
In electric pumps the impeller and the end shields are made from carbon steel, which eliminates the failure of the parts and keeps metal particles from entering the oil, being handled.
The design (construction) of electric pumps admits both horizontal and vertical in¬stallation by the suction branch upwards or downwards.
