In the MPN 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-in inside the impeller. Therefore, a rigid shaft passage is not necessary.

Advantages of the MPN Pump Series: PVDF PP

- hermetically sealed, absolutely leak-proof - highest chemical resistance - robust design - without vulnerable (floating) axles - low-maintenance through double hydro-dynamic slide bearings with extra big radii - long-lasting and wear-resistant through axial thrust compensation - self-cooling design for the operation under demanding conditions - half-open impeller (i.e. solids up to 3 mm of grain size and 10 Vol. % are possible) - dry run safe within certain 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 - various chemical resistant materials can be supplied from stocked inventory - available as explosion proof version for combustible environments (ATEX)

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
