SCHMITT PERIPHERAL MAGNETIC DRIVE PUMP - P RANGE
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.Materials of construction: Medium contacting parts are made solid of PVDF whilst Housing seal is alternatively made of FKM, EPDM, FEP or Kalrez®. Slide bearings are made of the materials PTFE/ceramic.
P Series main features:
- 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
A small amount of gas in the liquid can also be transferred without disrupting the liquid flow.
