Normal-priming peripheral pumps: P series

  • Normal-priming, magnetically coupled impeller-type peripheral pumps
  • Materials: PVDF (polyvinylidene fluoride)
  • Hermetically sealed
  • Particularly suitable for small volume flows and high pressures
  • Max. output rate: 40 l/min
  • Max. discharge head: 32m
  • Motor power:  1.1KW

Description

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
