Immersion pumps with efficient motors
This company’s Series 700, 800 and 900 immersion sump pumps (photo) are available with variable-frequency drive (VFD) motors. These vertical immersion sump pumps built for sump drainage, flood control and process drainage meet U.S. EPA and OSHA requirements. Depending on the speed selected, the VFDs provide the capability of varying flow and head performance from a vertical pump. These motors offer a cost-effective method of varying the pump performance as desired while conserving energy consumption. The Series 800, for example, provide heads to 230 ft and up to 3,000 gal/min flowrates, and operate at temperatures to 350°F and pit depths to 26 ft. These vertical, immersion sump pumps have a semiopen impeller, external adjustment, and come standard with NEMA C face motors (VFD motors are optional). — Vertiflo Pump Company, Inc., Cincinnati, Ohio
