Dickow Pumpen launches new safety-conscious seal-less magnetic coupled gear pumps

German pump manufacturer Dickow Pumpen has introduced new GML/GMB seal-less magnetic coupled gear pumps for use across a range of industries.

The magnetic driven pumps are designed to improve plant and personnel safety, particularly when handling toxic, explosive, and dangerous liquids which react on contact with the atmosphere.

With a containment shell replacing single or double acting mechanical seals with external fluid reservoirs and the necessary control equipment, the pumps are ideal for the chemical, petrochemical and allied industries, and are also environmentally sound.

A patented lubrication method ensures an overall longer lifespan, while components made of tough materials can handle the stresses of high viscosity operation.

The single elements of the multipolar magnetic coupling are made of permanent magnet material 'cobalt samarium', with unlimited lifetime. The magnets in the driven rotor are completely encapsulated, ensuring no contact with liquid.

Power is transmitted to the hermetically sealed liquid end by a bank of external magnets. Inner and outer magnet rings are locked together by magnetic forces and work as a synchronous coupling. The containment shell is a one piece deep-draw design without additional welds.
