ELECTROMAGNETIC PUMP Russian patent published in 2007 - IPC H02K44/02 F04F11/00 

FIELD: mechanical engineering, possible use in metallurgy for pumping liquid metals and alloys.

SUBSTANCE: electromagnetic pump contains pump channel, input and output branch pipes, three "U"-shaped magnetic ducts are introduced and one closed "m"-shaped magnetic duct with winding enveloping its central rod and connected to current supply. Pump channel, in the unit for connection to input branch pipe, is made with two branching sleeves, which are interconnected in the unit of connection to output branch pipe. Branching unit is enveloped by "U"-shaped magnetic duct, and connection unit is enveloped by two "U"-shaped magnetic ducts, positioned at an angle of no more than 90 degrees to each other. One sleeve is positioned in one of apertures of "m"-shaped magnetic duct, and another sleeve in second aperture of this magnetic duct, so that pump channel forms a closed electric contour around central rod of "m"-shaped magnetic duct. The channel in places of branching and connection units is made with rectangular cross-section.

EFFECT: increased productivity of the pump.
