Flow rate: 12 l/min. (explosion-proof)

The 70V industry is suitable for pumping watery up to highly viscous liquids with and without fibre or solid content. Driven by Lutz universal motors with 230V, AC voltage or compressed air motors.

Liquid examples:
Ideal for pumping viscous mineral oils, cosmetics, food, resins, emulsions, paints and many other viscous materials.


  • For shear-sensitive and viscous liquids
  • Displacement pump with reduction gear using the eccentric screw principle 
  • Convenient for all Lutz universal motors and compressed air motors
  • Easily detachable outer pipe


  • Gentle product pumping
  • Constant flow
  • Ideal for mobile application
  • Easy handling
  • Simple cleaning
  • 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:
