Eccentric screw pump B70V in PURE version, Ex (with three-phase motor motor)


The B70V in PURE version is a powerful eccentric screw pump for medium-viscous, highly viscous...more
Flow rate: 12 l/min. (non ex-proof)

The B70V in PURE version is a powerful eccentric screw pump for medium-viscous, highly viscous and slow-moving liquids up to the limits of flowability. Alternatively driven by direct-coupled three-phase motors

Liquid examples:
Ideal for pumping viscous mineral oils, cosmetics, food, resins, emulsions, paints and many other viscous materials. 


  • For medium viscous up to highly viscous liquids and hardly flowable liquids
  • Displacement pump with bearing flange using the eccentric screw principle
  • With three-phase drive
  • Drive motor optionally available with integrated frequency converter.
  • Pump tube with Tri-clamp connection
  • Special application in the food and cosmetics industry
  • For mobile and stationary application
  • Easily detachable outer pipe


  • Gentle product pumping
  • Constant flow
  • A large selection on robust and powerful drive motors
  • Controlled speed adjustment (with frequency converter)
  • Simple cleaning
  • Smooth running and low wear

Sealing system:
Mechanically sealed (MS)

Drive shaft:
Torsion shaft or universal joint shaft


Immersion length:
1000 and 1100 mm


All materials coming into contact with the pumped liquid are physiologically safe.
The pump tubes are mainly used in the food, cosmetics and pharmaceutical industry.
