Archimedean screw pumps are an ancient type of positive-displacement pump that works like a conveyor. Also known as Archimedes screws, they are ideal for pumping unscreened liquids due to their capability to carry large solids. Their common applications are flood control, sewage lift stations, and primary influent. 

Archimedes screw pumps are an excellent choice for large flow applications, as the wire-to-water efficiency averages in the 80% range for units mounted at 30°. 

Landustrie’s screw pump design 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 experts, at Landustrie, to ensure the best return on investment for every project.

EPIC / Landustrie Screw Pump Features & Benefits

  • Two upper bearing designs: floor-mounted and gas-tight wall-mounted.

  • Three lower bearing designs: traditional grease-lubricated, heavy-duty trunnion-type grease-lubricated, and Eco-Friendly oil-filled.

  • Design capability up to 5m diameter and 25m length, with the capability to manipulate many design features to reach the most efficient size and speed to reduce initial costs.

  • Cast shafts, reinforced flight starts, counterbalanced lifting eyes, reinforced, sealed bolt holes in torque tube endplates, shot blasting, and full-factory painting are all standard.

  • Stainless steel screw pumps are available, as are multiple full-factory coating options to meet specific operating environments.

  • Multiple screw pump systems are offered: traditional open-flight screw pumps in concrete troughs, screw pumps in self-supporting steel troughs, screw pumps in tube-type troughs, and others.

  • EPIC screw pumps are compatible with the EPIC flight deks, which are designed and manufactured in Virginia.
