Abstract
A corrosion-resistant pump for propelling a fluid therethrough, the pump comprises a first magnet for providing a magnetic field. A motor is attached to the first magnet for rotating the magnet. A container is placed adjacent said first magnet for preventing the fluid contained therein from contacting the motor and the first magnet. A second magnet is disposed within the container and magnetically interacting with the first magnet which interaction, in turn, causes the second magnet to rotate simultaneously with rotation of the first magnet. The second magnet is coated with a ceramic magnetic material on its first portion and a bulk ceramic magnet attached to its second portion for preventing corrosion of the magnet and enhancing magnetic flux with the second magnet. A propeller is disposed within the container, and is attached to and simultaneously rotates with the second magnet for propelling the fluid through the container.
