What is a magnetic drive pump?

"Magnetic drive" refers to the coupling between the part of the pump in contact with the liquid and the motor. In direct drive pumps, the impeller of the pump is connected to the shaft of the motor. This design depends on the shaft seal to contain the chemicals. In the magnetic drive pump, the wet end and the motor are two separate containing parts, connected only by the motor bracket.

A drive magnet is installed at the end of the motor shaft. When the drive magnet rotates around the rear housing, the impeller fixed on the other magnet will rotate synchronously. In the absence of shaft seals and the possibility of leakage, corrosion-resistant magnetic drive pumps play a good role in fields involving corrosive, toxic, flammable, expensive or environmentally harmful liquids.

How does a magnetic drive pump work?

The attractive force of the driving magnet and the impeller magnet causes the entire torque of the motor to be transmitted to the impeller. Since the shaft of the motor does not extend into the inside of the pump, no shaft seal is required. Since the impeller is not fixed on the motor shaft, the impeller floats in the pump casing. The impeller rotates at the same speed as the motor and is supported by a fixed shaft. The impeller is a moving part in contact with liquid. Without shaft seals, the leakage hazards normally associated with shaft seals can be eliminated. In addition, since there is no need to spend time or money to maintain or replace the shaft seal, maintenance costs are reduced.

What is a corrosion-resistant magnetic pump?

Corrosion-resistant magnetic pump refers to the use of corrosion-resistant materials, such as glass fiber reinforced polypropylene (pp) and polyvinylidene fluoride (pvdf) made of high temperature, acid and alkali resistant magnetic drive pump.
