Abstract
Electromagnetic pump for electrically-conductor fluid containing an external pipe (1) enveloped by magnetic half-yokes (11, 11') containing slots (14) in which half-coils (19, 19') are installed forming two polyphase half-windings (35, 35') permitting a symmetry plane. The fluid is contained in a duct (31) comprised between the external pipe (1) and an internal pipe (5) which is closed and contains a magnetic core (24). The duct (31) is provided with partitions (29, 29', 34) which separate the duct (31) into two active half-ducts (32, 32') in which the fluid flows and two passive streams (33) in the vicinity of the joint plane in which the fluid scarcely flows at all. Pump with a high degree of efficiency and easy to dismantle.
