Magnetic pump using ferromagnetic powder - has two drops of ferromagnetic powder displaced around hollow ring via magnetic fields

摘要

The magnetic pumps using a ferromagnetic powder has a hollow ring (3) with an inlet (4) and an outlet (5), containing two drops (1, 2) of a ferromagnetic powder, displaced independently via magnetic fields between the inlet (4) and the outlet. The magnetic fields are provided by a permanent magnet system and an electromagnetic coil (7) providing a moving field with a higher field strength. An iron core may be contained within each drop (1, 2) of ferromagnetic powder. ADVANTAGE - Simple maintenance and repair.
