ROTOSCREW
Archimedean Screw Pump

Model SPK

This powerful Screw Pump is predominately used for lifting low-lying water / wastewater to higher elevations. The ROTOSCREW Pump works by a rotating 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.

The ROTOSCREW ‘SPK’ 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 in either concrete troughs or integral steel trough housings and support structures.

OPERATION PRINCIPLES

The powerful screw collects water at the lower end and forces it up the trough until it discharges at the top.
