Magnetic Drive Pump

Magnetic Drive Pump is a type of seal less pump which uses a permanent magnetic coupling to transmit torque to the impeller without the need for a mechanical seal for packing.

How does a Magnetic Drive Pump works?
Magnetic drive pump uses a standard electric motor to drive a set of permanent magnets that are mounted on a carrier or drive assembly. These are located outside the containment shell. The drive magnet assembly is mounted on a second shaft which is driven by a standard motor. The external rotating magnetic field drives the inner rotor.

Types of Magnetic Drive Pumps:

• Rotating driven shaft : This pump is usually made of metal and it includes a pressurized recirculation circuit to help prevent vaporization of the liquid required to lubricate the bearings.
  
  
• Stationary shaft : This pump uses non-metallic components such as ceramics and plastics and is best suited for light to medium duty applications.

Uses and Features of Magnetic drive pumps:

• Magnetic drive pump is capable of pumping a variety of liquids.
  
  
• There are some magnetic drive pumps which move abrasive materials, acids, adhesives, chemicals, concrete and grout, coolants, hazardous materials, liquid metal, or lubricants.
  
  
• There are some for combustible, corrosive, high viscosity, or high temperature media.
  
  
• It is also used to move gasoline, diesel fuel, and oil, ground water, potable water, salt water, and wastewater; sewage, sludge, slurry, gas and air; powders, solids, and rendering wastes.
  
  
• Important specifications for magnetic drive pumps are like maximum discharge flow, maximum discharge pressure, inlet size, discharge size, and media temperature.
  
  
• Power sources for magnetic drive pumps are compressed air, gasoline, diesel fuel, solar energy, alternating current (AC), and direct current (DC).
  
  
• There are small DC-powered magnetic drive pumps (6, 12, 24, or 32 volts), single-phase motors (100, 115, 200, or 230 volts) and three phase motors (230--690 VDC).
  
  
• Manually powered magnetic drive pumps rely upon hand or foot power.
