Electric power pump units "1TT" - centrifugal transfomator traction with an integrated electric motor, sealed, wet -mounted with a closed -type work wheel - are designed to pump transformer oil with a temperature of 258 to 378 K (from -15 to + 105 ° C) - 1tT 63/10, from 273 to 378 K (from 0 to + 85 ° C) - 1tT 16/10 in the cooling systems of power transformers of mobile units. Transformer oil should comply with the requirements of GOST 982 and GOST 10121, except for the oil tk.
In electric pumps, the working wheel and bearing shields are made of carbon steel, which eliminates the destruction of parts and the ingress of metal particles into the pumped oil.
The design of electric pumps 1tT 63/10 allows both a horizontal and vertical installation by a suction pipe up or down. 1TT 16/10 - horizontally pressure pipe up or down.
