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

Fördermenge:

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

Features:

  • 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

Benefits:

  • 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

Stator:
NBR light, FPM or PTFE

Immersion length:
1000 and 1200 mm

Also available with circulation/rinse connection

Viscosity (up to mPas): from 100.000 mPas (e.g. tar), up to 4.000 mPas (e.g. shampoo), up to 20.000 mPas (e.g. honey), up to 30.000 mPas (e.g. jam), up to 100 mPas (e.g. milk), up to 100.000 mPas (e.g. toothpaste), up to 500 mPas (e.g. hydraulic oil), up to 1500 mPas (e.g. baby food)
