Archimedean Screw Pump

This powerful Screw Pump is predominately used for lifting low-lying water/wastewater to higher elevations. The ROTOSCREW Pump works by rotating a motor driven inclined screw that is housed within a concrete/steel trough which raises-up large volumes of water, delivering powerful pumping results. This pump design is ideal for water transport applications, including wastewater sewage treatment, irrigation and flood control.

ROTOSCREW is an open type Archimedean Pump supported by a heavy-duty upper bearing and a specially designed, hermetically sealed, self-lubricated lower bearing. The upper bearing is designed to take both axial and radial loads while the lower bearing simply provides radial support.

Designed and manufactured with multiple flight ranges and inclination degrees, the ROTOSCREW is highly adaptable to accommodate even the highest flow and lift needs. It can be installed either in concrete troughs or integral steel trough housings and support structures.
