Coil motor transformer oil pump is a new type of electrical centrifugal oil pump used for powerful oil cooling circulation of the transformers and rectifiers.

The series of transformer oil pumps use axial air gap to induct coil motor and is installed directly into the pump shell. The motor rotor is installed on the blade of the oil pump to form a whole of pump and motor. The axial electromagnetic power of oil pump motor can reduce the axial load shock on the blades, which can prolong the service life of the bearings. The pump shell is made of welded steel plates with the least sealing construction. Compared with traditional centrifugal oil pump, it has the characteristic of short axial length, close but reasonable construction, steak and reliable functioning, low noise, high efficiency, light weight, no seepage, long service life and convenient usage and maintenance¡.
