Robust, stable sand-resistant deep well screw pump made of stainless steel for extremely deep well drilling from 100mm diameter (up to 120m). With this robust deep well screw pump the pumping of water from extremely deep boreholes, wells or water reservoirs is no problem. It pumps this water at high pressure to the point of use.
This is one of the few real deep well pumps that can handle sand quantities where the usual impeller pumps fail after a short time! However, the higher the sand content, the higher the wear of the screw conveyor and the coupling.
How do you determine how much sand is in the water? Simply pour 500-1000L of water into a high container so that water runs over the edge, but the sand can settle. Measure the amount of water and then the weight of the deposited sand. Then form the quantity ratio.
