Eccentric screw pump B70V-SR 12.1 and 25.1

Lutz Drum and Container Pumps
Eccentric screw pump B70V-SR 12.1 and 25.1
B70V-SR 25.1
with motor MA II 5

The B70V-SR is suitable for aqueous to highly-viscous substances with or without fibrous or solid matters. The pump is either operated with Lutz universal motors 230V AC or with compressed air motors.

Liquid examples:
Ideal for viscous mineral oils, cosmetic products, foodstuffs, resins, emulsions, colours, etc.

Features:

  • For shear sensitive and sticky liquids from 1 to 30.000 mPas
  • Positive displacement pump with planetary gear according to eccentric screw principle   
  • Suitable for all Lutz universal motors and compressed air motors
  • Easy detachable pump tube
  • Explosion-proof version in compliance with ATEX 94/9/EC, categorie 1/2

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

Drive shaft:
Torsion shaft (TS) or universal joint shaft (UJ)

Immersion length:
1000 mm

PU

For food- and cosmetics industry
also available in physiologically safe version (PU)

Benefit:

  • Smooth flow
  • Constant volumetric flow 
  • Ideal for mobile use
  • Ease of handling
  • Easy to clean
  • Low wear
