DeRagger Pump Monitoring System

Kerr Pump & Supply offers the Deragger pump monitoring system that will eradicate pump clogs in wastewater pumps.  The Deragger+ constantly monitors a pump motor’s torque signature and can dislodge rags 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 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.
