In the MDN Pump Series, the motor power is transmitted contact free and abrasion-free with a magnetic coupling through the closed housing wall (“Slot-pot”) to the pump impeller. An encapsulated counter-magnet is built-inside the impeller. Therefore, a rigid shaft passage is not necessary.

Advantages of the MDN Pump Series:
dry run safe
hermetically sealed, absolutely leak-proof
highest chemical resistance
robust design
low-maintenance through double ceramic ball bearings
long-lasting and wear-resistant through axial thrust compensation
self-cooling design for the operation under demanding conditions
no abrasion into the medium to be pumped (high purity applications)
negative pressure tight for vacuum systems
no metal parts are in contact with the medium
easy to maintain (wear parts can be changed swiftly)
universally applicable, quiet and compact
The MDN Pump Series is particularly suitable for toxic or environmentally hazardous media. A small amount of gas in the liquid can also be transferred without disrupting the liquid flow.

This results in application possibilities, amongst others, for the following application fields:
Electro-plating technology
Wastewater treatment
Laboratory and medical engineering
Wafer production
Printed circuit board (PCB) manufacturing
Solar cell production
Analytical instruments
Semiconductor technology
Zoological seawater aquaria
Environmental technology
Wastewater treatment plant dosage
