Abstract
FIELD: mechanical engineering. SUBSTANCE: pump comprises working wheel mounted on the shaft of an electric motor with autonomous cooling circuit having auxiliary impeller to provide circulation of cooling liquid at the other end of the shaft of the electric motor. In the sucking space of the auxiliary impeller is working member of reverse hydraulic machine provided with own drive. The drive of the reverse hydraulic machine is made up as an electric motor that can operate as a generator. The electric motor of the reverse hydraulic machine is energized by a source independently of a power source of the major electric motor of the pump. EFFECT: enhanced efficiency.
