Auger deep well pumps

Auger

— pumps operate on the principle of the Archimedes' screw and use a spiral auger to supply water. Such a design is indispensable when working with contaminated water — the auger can pass even fairly large mechanical particles through itself and in large quantities. In addition, pumps of this type operate quietly and practically vibration-free. Their main disadvantages are low performance and a high price.
