A new type of a liquid metal pump has been developed for efficient contactless dispensing out of industrial metal furnaces. The concept consists of two opposing arrays of cylindrical diametrically magnetized synchronously rotating permanent magnets (Fig.1). The magnetization directions of the magnets are phase-shifted in respect to each other to maximize magnetic field strength and reduce oscillating forces between the magnets and overall torque. Numerical modelling for magnetic fields, resulting forces and torques was done with Comsol in 3D. A numerical model was built in order to verify the analytical model, where it was possible. It was found that there exist 3 minimums for the sum of the torques. These calculations gave the mechanical constraints needed to construct such a device.
