ITT Corp.'s Water and Wastewater group has won the 2011 Innovative Technology Award from the Water Environment Federation (WEF). Awarded in the collection systems category, Flygt's patented N-pump is further improved when equipped with the newly designed Adaptive Impeller functionality.
Field tested with a successful 10 year track record, the N-pump has proven to reduce energy consumption by up to 60% with clog removal maintenance virtually eliminated. Now, in conjunction with the innovative Adaptive Impeller, small solids-handling pump performance is further enhanced. The Adaptive self-cleaning N-pumps have been recognized by WEF as the single greatest technology innovation during the year.
The new enhanced design allows the N-impeller to move axially to allow easy passage of trash. When large pieces of trash enter the volute, the patented Adaptive version of the N-impeller allow it to rise momentarily and axially upwards within the pump volute housing enabling the very large pieces of trash, rags or debris to pass through the pump.
After passage of the debris, the N-impeller immediately returns to its normal operating position in close proximity to the volute insert ring. The advanced design is now available for small N-series pumps.
