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

The 70V in PURE version 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.

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

Features:

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

Benefits:

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

Sealing system:
Mechanically sealed (MS)

Stator:
PFTE

Immersion length:
1000 and 1100 mm

All materials coming into contact with the pumped liquid are physiologically safe.
The pump tubes are mainly used in the food, cosmetics and pharmaceutical industry.

Viscosity (up to mPas): 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 500 mPas (e.g. hydraulic oil), up to 1500 mPas (e.g. baby food)
Explosion Protection: explosion-proof
