In the village of Hartland, Wisconsin, submersible pumps at the village’s lift stations were frequently becoming clogged, resulting in emergency service calls to remove debris. The unscheduled calls had become a major expense, as overtime hours and unplanned maintenance costs increased.
The village of Hartland replaced two multi-channel-equipped submersible pumps at its clog-prone Crystal Drive Lift Station with two Flygt brand 5-horsepower pumps. The new pumps feature patented N-technology with self-cleaning impellers and pump housings. Backswept leading edges on the pump impeller shed rags and stringy material with each rotation, and the pump housing has a groove that channels the fibrous material away.
