Hermetic centrifugal pumps of the CTR type are intended for forcing the circulation of transformer oil through the oil cooler of large power transformers and can be used as circulation pumps in the heating system of energy station rooms with heat contained in transformer oil.

The CTR pump has a glandless construction and is a hermetic monoblock containing a centrifugal pump wet electric motor.The pump body and motor housing inside of which the pump rotor and motor rotor are located on a common shaft are connected through a bearing cover. The shaft is mounted in rolling bearings, the front of which is located in the bearing cover. All connections of pump and motor elements are sealed with O-rings made of oil-resistant rubber. Thanks to the arrangement of holes in the bearing cover and the channels in the pump shaft oil circulates through the internal circulation, which results in engine cooling, bearing lubrication and reduction of the axial force in the bearings to a minimum. The terminal box space is separated from the motor space by a sealed clamping plate, through which also the sealed terminal pins supply voltage to the motor stator windings.Electricity is supplied to the terminal box through a tight cable gland.
During transport and storage, tight sealing of pump connectors is required. Since the pumped oil is also a cooling and lubricating agent in the engine, its absolute purity is required.
At present, we manufacture pumps of the following sizes:
CTR-125-5.5 with a 5.5 kW motor
CTR-125-5,5A with a 5.5 kW motor
CTR-100-3 with a 3kW motor
