Description

Normal-priming peripheral impeller pumps: P series

Note: P130 series has been replaced by P140

 

Design:

  • Chemical-resistant, single-stage plastic peripheral impeller pump in close-coupled design, with magnetic coupling, normal priming

Features:

  • Hermetically sealed and absolutely leak-free, as there is no shaft seal as a matter of principle
  • Non-contact magnetic actuator with high-performance neodymium magnets
  • Virtually maintenance-free in normal operation thanks to generously dimensioned plain bearings
  • All wetted parts made of high-quality, corrosion-resistant plastics (PVDF or PP-GF)
  • Equipped with threaded connections to ISO 228-1 as standard
  • Universally applicable, compact and quiet
  • Approved for use in potentially explosive environments (ATEX Zone 2)
  • Corrosion-resistant paint finish in RAL 1017, saffron yellow
  • All screws made of V4A stainless steel (1.4571)
  • All wetted materials with FDA approval (PVDF series)

Areas of application:

Pumping acids, alkalis or other corrosive, harmful or toxic liquids in applications where leakage of even the smallest quantities is undesirable and a hermetically sealed pump is required.

Pumping of high-purity or sensitive liquids where contamination of the pumped liquid with foreign matter must be avoided.

 

For example in the following applications:

  • Electroplating and surface coating
  • Wet chemical processes in semiconductor technology, solar cell production and printed circuit board manufacturing
  • Waste water and fresh water treatment
  • Laboratory and medical technology
  • Environmental technology, exhaust gas purification, gas scrubbers
  • Battery production, energy storage
  • High purity applications, demineralised water, ultra-pure water

Technical data

Materials:

  • Housing and impeller materials: PVDF, PP
  • Elastomer materials: EPDM, FKM (e.g. Viton®), FEP, FFKM (e.g. Kalrez®)
  • Plain bearing materials: PTFE-GF, Al2O3 ceramic, SiC (silicon carbide)

The P series is designed according to the peripheral wheel principle. The special impeller and housing geometry

enable high pressures. The motor power is transmitted contact-free and wear-free via a magnetic coupling through the closed housing wall (containment shell) to the pump impeller.

Advantages:

  • Very precise control possible due to linear performance curve
  • Hermetically sealed and absolutely leak-free, as there is no shaft seal
  • Ideal for use with toxic, environmentally hazardous and aggressive media
  • Very suitable for pumping low-boiling liquids

The maximum media temperature is 60°C. This pump is also available in an Atex-certified version under the designation P-EX for use in ATEX zone 2.
