Lutz Drum and Container Pumps
Eccentric screw pump B70V-D 80.1 and 120.1
B70V-D 120.1
with 3-phase gear motor

The B70V-D 80.1 and 120.1 are a powerful eccentric screw pumps for semi-viscous or even highly viscous, tough media right up to their flowability limits. Driven by speed reduced three-phase gear motors or variable gear motors. 

Liquid examples:
Ideal for viscous mineral oils, cosmetic products, foodstuffs, resins, molasses, honey, low-viscosity grease, etc.

Features:

  • For highly-viscous media, right to their flowability limits from 1- 120.000 mPas
  • For high flow rates
  • Positive displacement pump with bearing flange according to eccentric screw principle
  • For stationary use
  • With powerful three-phase (variable) gear motors


Sealing system:
Mechanical seal (MS) or packing gland (St)

Drive shaft:
Universal joint shaft (UJ)

Immersion length:
1000 mm
