ARCHIMEDEAN SCREW PUMPS
Screw Pumps are an ancient type of positive-displacement pump that works like a conveyor. Also known as Archimedes screws or Archimedean Screws, they are ideal for pumping unscreened liquids due to their capability to carry large solids and manage high-flow applications. Their common uses are for flood control, sewage lift stations, and primary influent.
Screw pumps work by collecting "buckets of water" in the space between each screw flight, with each turn of the screw itself. These buckets are carried up the trough as the pump rotates. The screw pump deposits the buckets at the discharge point - also known as the chute point - at the top of the trough.
Archimedes screw pumps are an excellent energy-efficient choice for large flow applications. With wire-to-water efficiency averages in the 80% range for units mounted at 30°, you can achieve your pumping needs with minimal losses.
Our screw pump design by experts at Landustrie is based on a maximum desired capacity with a linear torque curve. They will self-regulate without the need to adjust the speed or any other parameter, and the power draw will reduce accordingly.
Open-flight screw pumps can run continuously both empty and overfilled with no detrimental effects on the equipment.
Archimedean screw pumps have been around for thousands of years, but they are still continually improved by our design and manufacturing professionals at Landustrie to ensure the best return on investment for every project. Landustrie has been a renowned technical expert as a screw pump manufacturer and designer since 1913.
