Lutz Verdrängerpumpe, Exzenterschneckenpumpe B70V Industrie mit Drehstrommotor

Eccentric screw pump B70V industry (with three-phase motor/compressed air motor)

Delivery rate:

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

The B70V industry 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 or compressed air 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 motor or compressed air motor
  • Drive motor optionally available with integrated frequency converter.
  • For mobile and stationary application
  • Easily detachable outer pipe
  • Ex-proof version approved category 1 / 2 (according to ATEX)
  • for pumping combustible liquids of the explosion group IIA or IIB (with circulation/rinse connection) and temperature class T4


  • 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) or packing gland (PG)

Drive shaft:
Torsion shaft or universal joint shaft

NBR light, FPM or PTFE

Immersion length:
1000 and 1200 mm

Also available with circulation/rinse connection
