How does a mag drive pump work?

The drive magnet is attached to the shaft operated by the motor. As the motor turns on, it spins the drive magnet which in turn spins the magnet attached to the impeller. The rotation of the impeller produces the power that drives the liquid through the pump.

Where are magnetically coupled pumps used?

Due to their seal-less design meaning they are not prone to leaks, magnetic drive pumps are very popular for the pumping of flammable, toxic and hazardous chemicals, acids and other potentially dangerous fluids that do not contain abrasives.

Can a magnetic drive pump handle solids?

No! The presence of solids can stick to the magnets and interfere with the operation of the pump.

Can a mag drive pump lose its magnetism?

Under extremely high temperatures or excessive torque the magnets may decouple meaning that the pump shaft can slip causing stoppages and inefficiencies.

The Gemmecotti HCM Series Centrifugal Magnetic Drive Pump is a thermoplastic magnetically coupled pump designed from solid block plastic to ensure a strong and resilient structure. The HCM mag drive pump series is designed for pumping highly corrosive liquids, including toxic, noxious and carcinogenic liquids. Due to the robust pump design, HCM magnetic drive centrifugal pump has a great resistance in terms of pressure and temperature, making it an ideal pumping solution for heavy-duty applications.

Thanks to its magnetic coupling, this mag drive pump benefits from not needing a mechanical seal that may be prone to wear, lowering the overall maintenance costs for the pump's life cycle. The magnetic sealing system ensures maximum safety and efficiency by removing the risk of any corrosive liquids leaking from the pump. Eliminating the seals for magnetically coupled pumps also get rid of associated friction loss, wear and noise, meaning cost-effective and efficient pump operation. Popular applications of the HTM magnetic drive centrifugal pump includes chemicals, corrosive, toxic, noxious and carcinogenic liquids, hydrocarbons, pyrophoric, heat transfer oils, refrigerants and cryogenics, radioactive liquids.

FAQs

Rather than having a mechanical seal to prevent liquid escaping from between the motor and pump shaft, magnetically coupled pumps use two magnets. The absence of mechanical seals that are prone to wear reduce the chance of leaking and maintenance.
