Conduction pump for corrosive liquid metals

Claim 1

A conduction pump for pumping corrosive liquid metals to a selectively adjustable discharge height and being immersible in said metals as well as capable of being dismantled comprising a duct for conveying said corrosive liquid metal, main magnetic circuit means including a first winding mounted on a first core member for producing an induction field at least at one section of said duct, secondary magnetic circuit means including a second winding mounted on a second core member for inducing a current in said liquid metal in said duct transverse to said induction field, a pump body formed of a plurality of detachable block-like elements made of refractory material mounted in stacked relationship with said duct being formed in aligned openings passing longitudinally therethrough, said detachable elements including a lower element provided with a recess for portions of said second core member of said secondary magnetic circuit means, at least one intermediate element having recesses for portions of said first core member of said main magnetic circuit means and other portions of said second core member said secondary magnetic circuit means and an upper element including recesses for other portions of said first core member of said main magnetic circuit means and of said second core member and secondary magnetic circuit means which pass therethrough.
