The P Pump Series is designed according to the peripheral impeller principle. The special impeller and housing geometry enables higher pressures and a linear characteristic. All parts in contact with the medium are made of PVDF (chemical resistant). The 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 P Pump Series:  |
- due to the linear characteristic, this pump can be very precisely controlled and metered - approximately double the pressure at the same size, compared to conventional centrifugal pumps - transfer also possible at rising back pressure e.g. when filters are clogging - building block system with a centric suction port - fully compatible with the MPN Pump Series (with few steps, at location, an MPN Pump Series can be converted to a P Pump Series) - hermetically sealed, absolutely leak-proof - the highest chemical resistance - low-maintenance through double hydro-dynamic slide bearings with extra big radii - long lasting and wear resistant (self-centering impeller, therefore no axial thrust) - self-cooling design for the operation under demanding conditions - robust design - vulnerable (floating) axles are not necessary - no metal parts are in contact with the medium - easy to maintain (wear parts can be changed swiftly) - very compact - negative pressure tight for vacuum systems |
The P Pump Series is particularly suitable for the frequency converter operation and for crystallizing media (no air can get inside), 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: |
- Spraying of chemicals through narrow nozzles - Very narrow installation space in plants - Electro-plating technology - Waste water treatment - Laboratory technology |
- Transfer through close meshed filters - Metering equipment - Laboratory and medical technology - Circulating pump for heat exchangers - Environmental technology |
