Magnetic drive centrifugal pumps are for transfer and circulation of corrosive and aggressive fluid. In magnetic pumps, the movement between the motor and the pump is transmitted without physical contact, but with magnets. This hermetically sealed design, makes it possible to avoid sealing problems, makes the pump resistant to dry working and piping-instillation errors. Magnetic drive pumps are especially preffered in the transfer of valuable fluid, where maintenance is not possible and the process is continuous and sensitive . The bearings and body metarials of the magnetic pumps are specially selected due to the working area and the characteristics of the fluid to be transferred.
