Screw pumps from Lakeside Equipment have a built-in variable capacity that automatically adjusts the pumping rate and power consumption while operating at a constant speed to match the incoming flow. They have a high rate of acceptance for their ability to lift water efficiently at any stage of the treatment process. They can be used in wastewater plant lift stations, return activated sludge, stormwater pumping, land drainage and industrial applications. They efficiently lift large quantities of water at low heads. Patterned after the Archimedean screw, the pump’s assembly consists of a simply designed screw, upper bearing, lower bearing and drive arrangement. They offer lower operating costs, reduced maintenance, nonclogging operation, minimal head and the elimination of variable-speed electrical controls. 630/837-5640; www.lakeside-equipment.com
