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.

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.

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 HTM Series Metallic Centrifugal Magnetic Drive Pump is a metallic magnetically coupled pump constructed in AISI 316 stainless steel as standard and in Hastelloy or Titanium on request. The HTM series of mag drive centrifugal pumps are only suitable for clean liquids that do not contain any solids in suspension, including highly corrosive fluids. Thanks to the innovative design of the Gemmecotti magnetically coupled pumps, there is no direct connection between the electric motor shaft and the impeller, meaning no mechanical seals that are prone to wear are needed, and the risk of leakage is eliminated.

The sealing of this centrifugal magnetic drive pump is maintained by a magnetic coupling, which removes the need for a mechanical seal and reduces the pumps maintenance costs. Eliminating the seals for magnetically coupled pump 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. The mag drive pumps series HTM are also available in ATEX versions for zone 1 and 2.

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.
