Xylem Wins Innovative Technology Award from Water Environment Federation

Flygt Experior’s clog-resistant design has been successfully field tested and proven to reduce energy consumption by up to 50 percent, with clog removal maintenance virtually eliminated. The award was presented to Xylem at the Water Environment Federation’s Annual Technical Exhibition and Conference (WEFTEC), the largest conference of its kind in North America.

Flygt Experior pumps incorporate state-of-the-art N-technology hydraulics, premium efficiency motors and intelligent controls in a package that is simple to install and easy to operate. These three complementary functions distinguish the fully integrated Flygt Experior system from traditional pump systems.

The muscle of the Flygt Experior is the premium efficiency motor coupled with ‘Adaptive N-hydraulics’ which further improves the results of the energy-saving, clog-free N-impeller. N-technology is suited for speed regulation as self-cleaning functionality is facilitated independently of rotational speed. Flygt SmartRun controls are pre-programmed with algorithms specifically designed for wastewater systems. The resulting pump performance delivers the ultimate in reliability, efficiency, and simplicity.

The self-cleaning Adaptive N-impeller was recognized by the WEF as the single greatest technology innovation during 2011. The Adaptive N-impeller moves axially upwards to allow easy passage of trash flow; the impeller then immediately returns to its normal operating position in close proximity to the volute insert ring eliminating clogging even under the most challenging conditions.

The Experior pumping solution now takes the wastewater industry one giant step further. "Extensive field trials in North America and Europe have proven that Flygt Experior only eliminates major clogging problems but also deliver extended service intervals while significantly reducing energy costs," said Lisa Riles, North America Marketing & Business Development Manager, Transport at Xylem Americas.

In Jefferson Parish, LA for instance, four problematic lift stations were retrofitted with one Experior pump each, which completely eliminated clogging problems after startup. Not one instance of pump failure or clogging has occurred. The Experior pumps are coping easily with huge amounts of trash like plastics, rags, baby wipes and straws.

"We are extremely pleased," said Linda Daly, PE, Parish Director of Department of Sewerage. "Despite heavy rains and I&I, we’ve not had any call outs for pump failures at the four locations that were retrofitted with Flygt Experior systems.”
