ARCHIMEDEAN SCREW PUMPS

RELIABILITY
Screw Pumps are an ancient positive-displacement pump that works like a conveyor. Also known as Archimedes screws or Archimedean Screws, Archimedean screw pumps 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 collect "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.  

FLOOD CONTROL

Archimedean screw pumps play a crucial role in flood control, working as an efficient tool to manage excess water levels. Their ability to handle large volumes of water with minimal energy consumption makes them invaluable in flood-prone areas. Whether installed in concrete, steel, or tube-type troughs, Archimedean screw pumps contribute significantly to mitigating the impact of rising water levels during flood events.

EFFICIENCY 
Archimedean 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 designed by the experts at Landustrie, a renowned screw pump manufacturer, is based on a maximum desired capacity with a linear torque curve. These screw pumps are designed to self-regulate, eliminating the need to adjust the speed or other parameters, resulting in a corresponding reduction in power draw.

Open-flight screw pumps can run continuously while empty or overfilled with no detrimental effects on the equipment.


INNOVATIVE TECHNOLOGY

While Archimedean screw pumps have been around for thousands of years, our design and manufacturing professionals at Landustrie consistently enhance their capabilities. We are dedicated to maximizing the return on investment for every project. Landustrie has been a renowned technical expert as a screw pump manufacturer and designer since 1913.
