Allweiler®’s eccentric screw pumps are self-priming, rotary positive-displacement pumps for handling and dosing low to high-viscosity, neutral or aggressive, pure or abrasive, gaseous liquids or liquids which tend to froth, even with fiber and solids contents.
Ranges of utilization include waste water and sewage engineering, chemical and petro-checmical industries, paper and cellulose industries, soap and fats industries, paint industry, food and beverage industry, plastics industry, ceramics, sugar industry, agriculture and shipbuilding.
Self-priming progressing cavity pump, the pumping elements of which are the rotating rotor and the stationary stator. The special shape of these two parts creates sealed chambers, the contents of which are continuously moved in an axial direction from the suction side to the pressure side. Despite rotation of the rotor, no turbulence results; the consistent chamber volume eliminates crushing forces.
