MAGNETIC DRIVE CENTRIFUGAL PUMPS

A couple of magnets leads the operation of the pump; the outer magnet placed on the drive shaft transmits the motion to the inner magnet integrated with the impeller that is hermetically insulated. The pump impeller is not physically fixed to the drive shaft, seals are therefore eliminated and this consequently avoids leakages of the liquid drawn by the pump which are usually due to its wear and tear. The pump head is manufactured with few components, thus the maintenance of which becomes extremely easy. The materials used as standard are polypropylene (pp) and polyvinylidene fluoride (pvdf).
The pumps can’t run dry. Dirty liquids can reduce the pump life
Working temperatures: PP min -10/max 65°c - PVDF min -10/max 90°c.

The new DM series magnetic drive centrifugal pumps consists of a variety of models with capacities ranging from 6,5 m3/h to 35 m3/h and with a total head which ranges from 8,5 mt to 24 mt.

Applications
DEBEM pumps are succesfully suitable for many different application fields such as: laboratory technique, medical equipments, photo processors, x rays film processors, laser beam systems, metal finishing machines, graphics, heat exchangers, aquariums, water treatment, filter units, chemical industry, galvanic industry.
