Eccentric screw pump B70V in PURE version (with three-phase 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.

Viscosity (up to mPas): 1,500 (e.g. baby food), 4,000 (e.g. shampoo), 20,000 (e.g. honey), 30,000 (e.g. jam), 100 (e.g. milk), 100,000 (e.g. toothpaste), 120,000 (e.g. tar), 500 (e.g. hydraulic oil)
Explosion protection: not explosion-proof
