"Using the DERAGGER we are saving over $1,200 per month, plus we can utilize staff for other activities instead of the constant pump cleaning."

Kishen Prathivadi, P.E, PMP, Sewer Authority Mid-Coastside

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 clogs, 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 ragging.

The reduction of environmental incidents, together with less electricity consumption, results in a lowered environmental impact and carbon footprint.

How does it work?

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.

Say goodbye to Chopper and Grinder Pumps!

The DERAGGER can be used INSTEAD of a Chopper or Grinder pump – making it a MUCH more cost efficient way to stop ragging. See what one customer said:

"The DERAGGER was installed on one pump that normally has a grinder, while that was sent off for a rebuild. The DERAGGER worked incredibly well. We will be purchasing DERAGGER systems for other problem stations in the near future.”

"I just wish this technology was available sooner!"

Pat Brook, Collections O&M Manager, City Of Missoula
"It’s an incredible solution to an age-old problem."

Tim Perry, Public Works Director, City of Palestine

Not only does the DERAGGER+ automatically prevent ragging 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 analyzed 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.
