Lutz Verdrängerpumpe, Exzenterschneckenpumpe B70V Industrie mit Drehstrommotor ex-geschützt

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): 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)
