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 HTP Series Self Priming Magnetic Drive Pump is a metallic magnetically coupled vane pump constructed in AISI 316 stainless steel as standard but has the option of Hastelloy or Titanium on request. Dighted for handling highly corrosive and non-lubricating liquids, this mag drive pump is ideal for transferring dangerous liquids, hydrocarbons, solvents, heat transfer oil, refrigerants, cryogenics and radioactive liquids. The Gemmecotti HTP vane magnetic drive pump is perfect for self-priming and low flow/high head applications such as pilot plants, sampling, and flushing mechanical seals.

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 seals are needed, and the risk of leakage is eliminated. The sealing of this vane pump is maintained by a magnetic coupling, which removes the need for a mechanical seal and ensures safety by eradicating the risk of any corrosive fluids leaking from the pump. This magnetic drive pump also benefits from a smooth operation, less noise and wear, meaning the HTP series provide efficient pump operation, cost-efficient maintenance, and long service life. Mag drive vane pumps series HTP are also available in ATEX version for zone 1 and 2.

The Gemmecotti HTP magnetic drive pump range is a vane pump designed for thin non-lubricating liquids and high differential pressure. Thanks to its design benefits, this mag drive pump series is usually used as a chemical transfer pump for transferring dangerous liquids, hydrocarbons, solvents, heat transfer oil, refrigerants, cryogenics and radioactive liquids.

Leak-proof design: The magnetically coupled design eliminates the risk of fluid leakage. As a result, there isn't any risk of wasting expensive products or leakage of hazardous fluids.
Reliable design: The HTP series of mag drive pumps have a simple design, which makes them extremely reliable pumping solutions that provide cost-effective maintenance and have a longer service life
Low maintenance: By eliminating the seals, this range of magnetically coupled pumps also gets rid of associated friction loss, wear and noise, meaning efficient pump operation and saving money on spare part costs.
Magnetic coupling: This magnetic drive pump requires no need for motor/pump alignment procedures due to being magnetically coupled.
ATEX Certification: HTP self-priming vane magnetic drive pump is also available with ATEX versions for zone 1 and 2.

The HTP magnetic drive pump is designed with maximum safety in mind and provide an efficient and reliable operation even for transferring non-lubricating fluids. In addition, the magnetically coupled pump series has a sealless design and high chemical resistance, making it an ideal chemical pump solution for highly corrosive applications.

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.
