Description and Specifications Magnetic Drive

A Magnetic Drive is a device made to transfer power and rotational motion between two rotating shafts without any physical contact. Magnetic Coupling is another name for it.

It is appropriate for various applications because it can convey unsteady torque. It does not require any maintenance because there is no physical contact involved. B24, B34, B/NS29/32, and B/NS45/40 are some taper glass joints that guarantee top-notch product quality without contamination.

To use a Magnetic Coupling, one of its ends should be attached to the glass vessel’s nozzle and the other to the stirrer motor. A glass shaft with a PTFE impeller is attached towards the bottom. The device is appropriate for use with glass jars up to 50 liters in volume and can withstand the torque of different overhead stirrers. It can run up to 3000 RPMs and is made of SS316, Hastelloy C, Inconel, PEEK, and Monel.

Main Highlights: 

  1. Leak-Free Operation: The drive pumps use seamless technology. This eliminates the need for mechanical seals. This means no leaks, even when handling corrosive chemicals. This lowers the maintenance costs and improves system uptime.
  2. Run-Dry Capability: The drive’s carbon bushing helps it withstand run-dry situations without damage. This feature is especially valuable in unsupervised settings.
  3. Chemical Resistance: Magnetic Coupling pumps are highly resistant to harsh chemicals. This increases plant safety for operators and technicians.
  4. Durability: The drive can work well even in extreme temperatures and tough chemicals.
  5. Low Maintenance: The drive requires little, with no mechanical seals to replace and corrosion resistance. Its pumps require little to no maintenance for long-term, reliable performance.

Applications of Magnetic Drive:

Magnetic Drive pump is helpful in various industries, especially where there is a chance of leakage. It is commonly used in pumps and compressors to transfer fluids. The absence of shaft seals makes the drive ideal for handling corrosive or hazardous liquids. Electric vehicles use it to transfer power from the motor to the wheels. Its efficiency and reliability enhance the performance of electric vehicles. It also finds application in moving flammable and dangerous fluids in the petrochemical industry.

How does a Magnetic Drive work?

  • It consists of two main components: a stator and a rotor. The stator is a stationary part that houses electromagnets, which an electric current can switch on and off. On the other hand, the rotor is composed of magnets and rotates. The stator electromagnets are activated to interact with the rotor’s magnet, which produces a magnetic field.
  • To create a force of repulsion or attraction, magnets on the rotor are aligned with the magnetic field generated by the stator. This force allows the rotor to rotate. The rotor is then controlled precisely by controlling the electromagnet’s activation and deactivation.

Safety Measures:

Follow these safety measures to avoid accidents 

  1. Magnetic drive can be fitted with overload protection systems to avoid damage in the event of an excessive load.
  2. The corrosion resistance of the materials used in it makes it appropriate for handling corrosive fluids.
  3. There’s a quick and reliable way to stop the drive-in emergencies or critical situations. There are emergency stop buttons or remote shutdown options to protect people and equipment.
  4. Preventing fluid leakage is made possible by the tightly sealed design, which guarantees no physical connection between the drive and driven parts.
  5. These are designed to keep electrical parts separate from external elements. This ensures the drive works safely within specific electrical limits and reduces the risk of electrical shocks.
