LEAKPROOF PUMP WITH PERMANENT MAGNET-BASED DRIVE AND CORROSIONPROOF BODY Russian patent published in 2015 - IPC H02K44/02 H02K5/12 H02K7/18 H02K21/12 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering and may be used in electric pumps with the drive based on permanent magnets. Leakproof pump with permanent magnet-based drive features the corrosionproof body containing a reinforced bracket, motor enclosure and the rear motor enclosure. The reinforced bracket is made of corrosionproof plastic; the motor enclosure and rear motor enclosure are made of aluminium alloy. Thus the corrosionproof body is capable to prevent chemical corrosion of components made of aluminium alloy. Besides the leakproof electric pump with permanent magnet-based drive represents mechanism for heat dissipation at simultaneous provision of the required structure for the corrosionproof body in such way that the electric motor can dissipate heat with sufficient rate.

EFFECT: prevention of chemical corrosion at components of the leakproof electric pump.
