Mag Drive Pump Guide

What is a Mag Drive Pump?

A Mag Drive Pump features your chosen pump technology such as Centrifugal and Rotary Vane but will be powered by a magnetically driven motor. This means that they do not have a mechanical seal between the pump and motor, giving them a sealless design. The mechanical seal component often leaves other pumps on the market prone to leakage.

How does a Mag Drive Pump work?

Power is supplied to the pump’s motor which rotates the motor shaft and turns a magnet. This magnet then drives an internal magnet which is typically surrounded by metal or a high-grade thermoplastic and is coupled to the internal rotation part of the pump that moves the fluid, typically an impeller. This turns the internal rotation and transfers your fluid through the pump.

How do Magnetically Driven Pumps differ from Mechanically Sealed Pumps?

Benefits of using a Magnetically Driven Pump over a Mechanically Sealed Pump:

  • Sealless design avoids wearing of the mechanical seal which risks expensive or hazardous fluids being leaked into the surrounding environment if a Mechanically Sealed Pump
  • Fewer moving parts increases the reliability of the pump
  • Fewer parts ensures easier maintenance for end-users
  • Coupling is magnetic so there is no need for complicated alignment procedures
  • Meets environmental and safety regulations

Which Pumps can be magnetically driven?

There are a range of pumps available on the market with a magnetically driven motor including:


  • Centrifugal Pump
  • Rotary Vane Pump
  • Regenerative Turbine Pump
  • Eccentric Disc Pump
  • Vertical Immersion Pumps
  • Gear Pumps

Advantages & Disadvantages of a Mag Drive Pump


  • Sealless design – No risk of hazardous or expensive fluids leaking
  • Manufactured from very few parts for simple maintenance for pump longevity and lower maintenance costs
  • Magnetic coupling – no alignment required of pumps and motors
  • Compact design making it ideal for OEM customers
  • High safety standards that adhere to site regulations
  • Longer working life because they don’t have a mechanical seal which is a wearing part
  • Low operational costs

Plus, each Mag Drive Pump will also benefit from the advantages of each individual pump type, for example, the standard benefits of a Centrifugal Pump can also be applied to a Mag Drive Centrifugal Pump.


  • Not for hygienic applications
  • Majority of Mag Drive Pumps cannot process solids
  • Higher upfront cost, however, this is balanced out by lower maintenance costs
  • Majority of designs cannot run dry
