Mag Drive Pumps
A description of Mag Drive technology

A Mag Drive pump is a type of sealless pump that utilizes a magnetic coupling to create a static shaft seal.  Magnetic force aligns the outer magnet (drive magnet) and inner magnet (driven magnet) through a stationary containment shell (canister).  This eliminates the hazards and mess caused by packing or mechanical seal failure.

Viking Mag DriveŽ pumps are not only ideal for:

  • Hazardous liquids like acids or caustics
  • Flamable liquids like fuels or alcohols
  • Strong aromatics like perfume or mercaptum

But are also a low life cycle cost choice for:

  • Difficult to seal liquids like resins or isocyanates
  • Expensive liquids like heat transfer fluids or pharmaceutical ingredients
  • Pump locations where seal leakage poses a safety or housekeeping concern
  • Pump locations where seal failure is absolutely unacceptable like pipelie sampling

The following graph illustrates the first year cost of a Mag Drive gear pump versus a mechanically sealed pump which had a single mechanical seal failure.  The savings value is dependent on the labor cost, cost of replacement seals, and downtime cost.

Over time, these savings compound, with some Viking customers realizing savings over $10,000US in just 3 years time.  Contact your Viking Pump authorized distributor to learn more.

Viking Pump introduced the first commercially available Magnetically Coupled gear pump over 2 decades ago, and has built on that tradition with the widest offering of Mag Drive gear pumps available today including the UMD Universal Mag Drive, the CMD Composite Mag Drive, the original Viking Mag DriveŽ, and the high pressure Spur Gear Mag Drive.
