Magnetic drive process pump featuring a unique mechanism with greatly improved performance against dry running

The MDM series have wetted parts made of fluororesins-natural PFA and CFRETFE being standard materials of construction. The MDM features a unique mechanism which gives a greatly improved performance against dry running (Non contact system).

Unique design prevents dry running

The pump design features a mechanism to withstand dryrunning. High magnet power of the rare earth magnets prevents the magnet capsule coming into contact with the thrust ring of the rear casing, thus preventing melting of fluororesin components due to heat generation. This greatly improves resistance against dry running in comparison with conventional magnetic drive pumps made of fluororesin.

ETFE and PFA available in standard models

Carbon fibre reinforced CFRETFE and PFA linings can be supplied to meet many varying duties. PFA being a natural unfilled material generates fewer contaminants and makes it ideally suited for transfer of high purity chemicals.

Highly durable structure

A ductile cast iron shell adds strength and durability to the outer peripheral surfaces of the fluororesin pump module. The rear casing which is placed under the highest stress is protected by a rear casing cover made from fibre reinforced plastic. This gives sufficient strength and eliminates the eddy current loss caused by the rotating magnetic field. Should it come into contact with the drive magnet unit, no spark would be generated and a high level of safety would be maintained.

Application examples:

Applications cover a wide range of chemical process duties from acid to alkali together with high purity chemicals for the semiconductor industry.
