The maintenance regime for a screw pump is considerably less complicated than that for a centrifugal pump which, unlike Archimedes’ design, can become blocked or overheat if it runs dry. Capable of moving large quantities of water over short distances, it is ideal for maintaining water levels and pumping water contaminated with debris that would seriously damage a centrifugal pump. The Archimedes screw pump is renowned for reliability and efficiency, which is why it is employed in so many applications, especially in the water treatment industry and drainage environments. Often running 24 hours per day these workhorses of the water industry can become neglected, but implementing a comprehensive maintenance regime will ensure continued reliability and efficiency levels.ĭave Bennion, Project Manager at ECS Engineering Services, looks at the importance of maintaining these vital assets. The enduring simplicity of the Archimedes screw pump continues to make it one of the most efficient pumping methods over short distances, but this efficiency should not be taken for granted.
