Mag Drive Pump Guide

Guide To: Mag Drive Pumps

Advances in pump technology have enabled engineers to reduce the size of magnetic drive pumps whilst increasing their power and efficiency.

 

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 pumps 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?

Here are some of the benefits of using a Magnetically Driven Pump over a Mechanically Sealed Pump:

• Sealless design avoids wearing of the mechanical seal which risks hazardous fluids being leaked into the surrounding environment of a Mechanically Sealed Pump
• Fewer moving parts increase’s reliability of the pump
• Fewer parts ensure 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 Pumps
• Rotary Vane Pumps
• Regenerative Turbine Pumps
• Eccentric Disc Pumps
• Vertical Immersion Pumps
• Gear Pumps

 

Advantages & Disadvantages of a Mag Drive Pump

Advantages:

• Sealless design – No risk of hazardous or expensive fluids leaking
• Manufactured from very few parts offers simple maintenance, 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 comes with 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.

Disadvantages:

• 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
