Magnetic Drive Centrifugal Pumps

Magnetic Drive Centrifugal Pumps - Applications


What is a Magnetic Drive Centrifugal Pump?

"Magnetic Drive" refers to the coupling between the wet end of the pump and the motor. In "direct drive" pumps, the impeller of the pump is attached to the shaft of the motor, and this design depends on the shaft seal to contain the chemical. In a magnetic drive pump, the wet end and motor are two separate contained parts, connected by only a motor bracket. At the end of the motor shaft, a drive magnet is attached, and as the drive magnet rotates around the rear housing, the impeller, which is fixed upon another magnet, spins in synchronization. It is the attraction of the drive magnet and the impeller magnet which allows the full torque of the motor to be passed onto the pump.


What are the benefits of a Magnetic Drive (Sealless) Centrifugal Pump?
  • Stop Leakage: No shaft seal = no risk of leakage
  • Maintenance cost reduction

As the shaft of the motor does not extend into the interior of the pump, there is no need for a shaft seal, and without a shaft seal, the danger of leakage commonly associated with a shaft seal is eliminated. Furthermore, the maintenance cost is reduced because no time or money is spent on maintaining the shaft seal. For a pump that eliminates the problems and costs associated with mechanical seals, our March Magnetic Drive Pumps have no equal.
