An electromagnetic pump for pumping fluids comprises an inlet 4, an outlet 6 and a section 8 having spaced apart positive and negative electrode 10,12 such that an electric current is passed through the fluid perpendicular to the longitudinal axis of the section 8, and spaced north south magnetic poles 16,18 such that a magnetic field is applied to the fluid perpendicular to the longitudinal axis of the section 8 and perpendicular to the electric current. Control means/generating means, provided to control/generate the current/field, may be respectively formed as a single device or as two separate devices. The pump may be operated in the manner of a valve applying a controlled resistance to fluid flow. |
