The multi-award-winning DERAGGER+ (previously called the DERAGGER II) from Clearwater Controls is the ideal solution for pump blockages and high energy costs – two of the biggest problems faced by the wastewater industry today.

  • Eliminates rags/clogs in wastewater pumps
  • Wealth of diagnostic information and pump data
  • Typical payback in months
  • Reduces operational callout costs
  • Improves electrical efficiency by up to 48%
  • Reduces pollution incidents
  • Minimal interruption to ‘live’ sites
  • No new kiosks, replacement panels or construction works
  • Simple plug and play to any starter type

The key feature of the DERAGGER+ low-voltage, electronic pump management system is real-time pump monitoring.

This enables the patented technology in the DERAGGER+ to identify and eliminate potential pump blockages, monitor the long-term condition of the pumps and reduce wear and tear caused by unbalanced loads.  By maintaining a clean impeller at all times, the DERAGGER+ ends the time-consuming and costly necessity of manually lifting pumps, thus eliminating downtime and other costs associated with pump blockages.  The reduction of environmental incidents, together with less electricity consumption, results in a lowered environmental impact and carbon footprint.

Not only does the DERAGGER+ automatically prevent blockages in real-time, it provides full pump diagnostic information. The wealth of pump performance data includes individual phase voltage, current and power to Kw/Hrs, run time and a number of start counters.

The device also logs daily average current and power consumption, plus average run cycle time. Three hundred and sixty-five days of data can be easily downloaded and analysed to show pump performance over a year, enabling the asset owner to determine maintenance or replacement schedules for the pumps.

Measuring just 35mm in width, the din rail mounted DERAGGER+ is designed to easily and quickly retrofit into existing control panels, making it the perfect solution for even the smallest pumping stations. It connects easily through plug and play, with In-line (DOL), Delta-wye (Star/Delta), Soft Start or VSD.
