Product catalog summary

Overview: The MDN Pump Series consists of normal priming, magnetically coupled pumps made from PVDF material, designed for high purity applications. These pumps are suitable for handling toxic or environmentally hazardous media and can manage small amounts of gas in the liquid without disrupting flow.

Applications: The pumps are used in various fields including electro-plating technology, wafer production, semiconductor technology, wastewater treatment, PCB manufacturing, zoological seawater aquaria, laboratory and medical engineering, solar cell production, environmental technology, and analytical instruments.

Specifications:

Max. output rate: 140 l/min
Max. discharge head: 14 m
Motor power: 0.55 kW

The motor power is transmitted contact-free and abrasion-free with a magnetic coupling through a closed housing wall to the pump impeller.

Advantages:

Dry-run-safe and hermetically sealed
High chemical resistance and robust design
Low-maintenance with double ceramic ball bearings
Long-lasting and wear-resistant with axial thrust compensation
Self-cooling design for demanding conditions
No metal parts in contact with the medium
Easy maintenance with swift wear part changes

Materials and Components:

Parts in contact with the medium are made of PVDF, suitable up to +95°C
Housing seals available in FKM, EPDM, FEP, or Kalrez®
Ball bearings made of SiC

Motor Details:

Standard motors: 230/400 V 3ph, 50 Hz, IP 55, insulation class F
Special designs available, including high temperature and special insulation classes
Explosion-proof motors available

Dimensions: The dimensions of the motors refer to three-phase standard motors, with specific measurements provided for the MDN 130 model.

Notes: All motors can be supplied for USA standards upon request. Technical details are subject to change without guarantee.
