Deragger Pump Monitoring System

Kerr Pump & Supply offers the Deragger pump monitoring system that will eradicate pump clogs in wastewater pumps. Deragger has significant advantages over Choppers or Grinders, which create particles that are passed through headworks screens and cause problems in treatment plant processes. Deragger does not. Deragger reverses the flow, dislodges the wipe from the impeller, then sends it along through the normal process.

The key feature of the Deragger+ low-voltage, electronic pump management system is real-time pump monitoring. The patented Deragger technology also can reduce wear and tear caused by unbalanced loads by monitoring the long-term condition of the pumps.

As a Deragger distributor, Kerr offers Deragger parts and an extensive service department that can assist with any pump system repair that is needed. Our service technicians are fully insured, certified and factory trained to ensure your satisfaction.

In independent testing, DeRagger kept station wells clean without the need for manual lifting and cleaning. See the tests results here.

As a Deragger distributor, Kerr Pump & Supply offers a range of Deragger products.

Deraggger+ and Deragger Lite

The Deragger+ and Deragger Lite end pump ragging and improve efficiency. The DERAGGER+ constantly monitors the torque signature of a pump’s motor, and can dislodge and pass rags in Real Time should they become stuck on or inside the impeller/volute. This is achieved with a tuneable “clean cycle” involving a brief and unique series of forward and reverse motions of the impeller.

Deragger+ ends the time-consuming and costly process of manually lifting pumps to clear the rags, thus reducing downtime and pump repairs.
