DERAGGER LITE Logo

The smart way to end ragging problems without changing or adding equipment.

"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
"It is working great for us and we have not had any ragging issues on that pump since it was installed in 2014"

The DERAGGER LITE™ anti-ragging device solves the problem of wastewater ragging, clogs and blockages – so no more wasted manhours, damage to equipment, possible risk to employees and risk of overflow or spillages.  By ensuring you constantly run a clean pump (or mixer, aerator etc.) it also prevents the negative impacts of running partially ragged equipment – such as vibration, decreased flow, longer run-times and higher power bills.

Our patented technology constantly looks for fluctuations in motor torque using voltage, current and speed.  This enables the DERAGGER LITE™ to detect the first rags to get stuck.  It then automatically runs a ‘clean cycle’, to pass the rags through.

The compact DIN-rail mounted unit (approximately 4″ x 5″ x 1.5″) is compatible with all starter types and is easy to retrofit.

  • The DERAGGER LITE™ anti-ragging device will eradicate pump clogs in wastewater pumps

  • Typical payback in 3-4 months

  • Reduces or eliminates operational callout costs

  • Improves electrical efficiency by up to 48%

  • Reduces spills and polluting incidents

  • Minimal interruption to ‘live’ sites

How does it work?

The DERAGGER LITE™ 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.

But won’t reversals damage my pump?

Our unique technology reverses a pump BEFORE a clog is allowed to form, meaning pump reversal is completely safe. Trying to run pump reversals through other methods (such as programming a VFD) will mean pumps could reverse when already clogged which COULD damage your pump! Most quality pump manufacturers have endorsed the DERAGGER and provided reversing guidelines.
