Lutz Progressive Cavity Drum Pump

The B70V-D/DA is a powerful eccentric screw pump for semi-viscous or even highly viscous, tough media right up to their flowability limits. For applications in the food, pharmaceutical and cosmetics industry, no special shaft joint is needed. The pump is either driven by 3-phase motors or compressed air motors.

Liquid examples:

Chemical industry:
acids, lyes, sludge, viscous pastes, dispersions, adhesives, etc.
Cosmetics industry:
creams, soaps, toothpaste, shampoos and raw materials for soaps.
Confectionery industry:
honey, syrups and preserves.
Paint and lacquer factories:
paints, lacquers and pastes
Food industry:
milk, whey, cheese, spread and ketchup.
Mineral oil industry:
high-viscosity oils and fluid greases
