The Gemmecotti HTM Series Non-Metallic Magnetic Drive Pump is a magnetically coupled centrifugal pump constructed in thermoplastic materials (PP or PVD). This range of mag drive pumps has a high chemical resistance and is designed for transferring clean liquids that do not contain any solids in suspension, including highly corrosive, toxic, noxious and carcinogenic liquids. Thanks to the innovative design of the Gemmecotti magnetic drive centrifugal 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 magnetic coupling that seals the pump means that a mechanical seal is not required, thus reducing the potential maintenance costs. This also increases the safety of the pump by significantly reducing the chance of corrosive liquids leaking. 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

Features of the HTM Mag Drive Pump:

  • Plastic magnetically coupled centrifugal pump
  • Suitable for highly corrosive liquids and chemicals
  • High torque magnetic coupling NeFeBo as standard
  • Low maintenance costs
  • 230V, Three Phase 50hz / 60hz motors available.

The Gemmecotti HTM magnetically coupled pump range is a centrifugal pump designed for transferring highly corrosive, toxic, noxious and carcinogenic fluids. Thanks to its design benefits, this mag drive pump series is a preferable option where a reliable chemical resistant pump is required.

  • Leak-proof design: The magnetic drive pump 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 HTM mag drive centrifugal pump series has a simple design, which makes it an extremely reliable pumping solution that provides cost-effective maintenance and has 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.

The HTM mag drive centrifugal pump is designed with maximum safety in mind and provide an efficient and reliable operation. In addition, the magnetically coupled pump series has a sealless design and high chemical resistance, making it an ideal chemical transfer 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.

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.

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.

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

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