Mag Drive Pumps

We've built a reputation as a quality supplier of mag drive pumps for applications benefiting from from seal-less designs across Minnesota, Western Wisconsin, North Dakota, and South Dakota.

Magnetic-driven pumps are one of the most popular form of seal-less pumps. They are used where a leaks-free process operation must be maintained such as with aggressive or risky liquids, exotic materials, acids, alkalis, corrosives, pollutants and toxics.   They are also useful for liquids that are difficult to seal and for liquids that must remain ultra pure.

Magnetic drive pumps, (magnetically coupled pumps), vary from traditional pumps in that the electric motor is coupled to the pump by magnetic means instead of a direct mechanical shaft. The major advantage is that the pump works via a drive magnet that eliminates any shaft sealing requirement. One of the disadvantages is that magnetic drive pumps cannot be used in some applications and can have limited power.

How do Mag Drive Pumps Operate?

In a magnetic drive pump,  the liquid pumped through the system exits at a different point than where it’s sucked into the pump. Liquid enters the pump, routes through the impeller and into a discharge chamber. The rotation of the impeller causes the liquid to increase in pressure, keeping if flowing so it discharges from the pump.  Mag drive pumps are a form of a centrifugal pump.

A typical magnetic drive pump includes a rotating impeller located in an enclosed housing powered by a rotating magnetic field produced by individual magnets. This rotation maintains energy and motion in a fluid to keep it from going stagnant or solidifying.

In a magnetic drive pump, the impeller and motor have magnets attached to them. Permanent magnets are attached to the pump’s drive assembly. The drive magnet, the magnet responsible for driving the inner rotor, is attached on a second shaft operated by the motor. When the motor turns on, it spins its magnet. The magnetic force from the motor’s magnet causes the magnet on the impeller to spin and rotate the impeller.

Viking Mag Drive Seal-less Pumps

8124A (cast iron) &  8127A (stainless steel)

The 8124A and 8127A Series are the ideal sealing technology within Viking’s Universal Product Line pumps. It is dimensionally interchangeable with other Universal Product Line pumps, allowing an easy upgrade from packed or mechanical seals to seal-less technology.

The 8124A and 8127A Series’ canister is hermetically sealed, providing the highest level of liquid containment available by eliminating traditional dynamic shaft seals traditionally associated with hazardous, hard-to-seal, or expensive liquids. It also eliminates housekeeping issues and downtime due to seal failure. This product is designed to handle a broad range of applications (such as caustics, isocyanates, adhesives, solvents and mercaptans).

This Series features 9 different sizes. They may be applied to both thin and thick liquids, and operate in either direction. They are also capable of operating under suction lift conditions. The series continues the tradition of most robust line of internal gear pumps built by Viking Pump

  • Magnetic Seal-less design protects product from environment.
  • Capacity: 500 GPM
  • Pressure: up to 200 PSI
  • Temperature: -60 to +450 °F (stainless steel up to 500 °F
  • Viscosity: 28 to 250,000 SSU
  • Positive displacement, internal gear pumping principle
  • Gear and pump geometry has been optimized based on more than 100 years of experience. These pumps are designed to provide exceptional reliability and freedom from down time and maintenance
  • Drop in foot print allows direct replacement of a Viking Universal Product Line pump without re-piping
  • Foot-mounted design
  • Available with 90° ports, which can be rotated in 90° degree increments, or with 180° ports (Check individual sizes).
  • Ports are threaded or flanged.
  • Pumps come with an adjustable internal pressure relief valve on standard design.
  • The pump operates in either direction, allowing one pump to be used for both loading and unloading. There is a slight reduction in capacity at viscosities less than 100 SSU with counter-clockwise rotation.
  • Adjustable end clearance for fluid viscosity or temperature by use of head shims.
  • Static O-rings at key points assures liquid containment.
  • Pumps conforming to ATEX hazard prevention requirements are available
  • Short-term Run-dry Capability. Unlike many mag drive pumps, the 8124A series may be run dry for short periods, such as for clear lines when unloading, or in the case of accidental empty tank situations.

At Edelmann & Associates, we know Mag Drive Pumps

What are the most common Mag Drive Pump applications ?

The  mag-drive pump (magnetically coupled) is the best method for handling toxic, noxious, crystallizing, or most other hazardous liquids since it completely contains the pumpage by isolating the drive shaft inside the pump housing. With no dynamic seal to leak or replace, the maintenance issues associated with seal leakage are eliminated.
