New Pumping System Offers Energy Savings

Xylem has unveiled a new wastewater pumping system called Flygt Experior. By combining advances to its state-of-the-art hydraulics, premium efficiency motors and intelligent controls in a unique concept, the new pump system offers up to 50 percent energy savings compared to conventional wastewater pumps in a package that is simple to install and operate.

Xylem Inc., the global water technology company that recently spun off from ITT Corp., has unveiled a new wastewater pumping system called Flygt Experior. By combining advances to its state-of-the-art hydraulics, premium efficiency motors and intelligent controls in a unique concept, the new pump system offers up to 50 percent energy savings compared to conventional wastewater pumps in a package that is simple to install and operate.

"Flygt Experior builds on the premise that to achieve the highest possible reliability, efficiency and simplicity, three fundamental functions hydraulics, motors and controls all have to be superior in performance and work seamlessly together," said Anders Fredriksen, head of Xylem/ITT's wastewater transport business area. "With the Flygt Experior, each critical function has been advanced by our team of world-class engineers and is optimized to work perfectly together."

Adaptive Hydraulics

The new Experior system will include an extended range of Adaptive N pumps, available on all N pumps between 1.3 and 7.4 kilowatts (kw), or 2.2 and 11 horsepower.

The Adaptive N-technology, introduced in 2009, allows the pump's impeller to move axially upward when necessary to permit bulky materials or tough debris to pass through smoothly, significantly reducing stress on the shaft, seals and bearings. This self-cleaning functionality helps bring down the total cost of ownership.

Recognizing its ability to deliver improved performance and energy savings, the Water Environment Federation named the Adaptive N-technology "The Most Innovative Product 2011."

Premium Efficiency Motors

Flygt Experior will be available with Premium Efficiency Motors up to 70 kw or 105 hp. The motors have been optimized for wastewater pumping applications, including some models featuring a Line Started Permanent Magnet, or LSPM design.

All of the new motors comply with international Premium Efficiency Standard (IEC 60034-30), commonly referred to as IE3, and with the LSPM technology the Flygt motors supersede the nominal standard by up to four percent. The LSPM design the world's first for a wastewater pump was first introduced in a Flygt compact mixer in 2009.

Smart Controls

SmartRun™ intelligent controls enable the pumping system to be pre-programmed and pre-set to handle any wastewater application, simplifying installation and operation. The controls optimize energy use and can reduce energy consumption by 30 percent compared to conventional on/off systems.

"Today there are generally two types of controls for wastewater pumping systems. Conventional on/off controls, which are simple to use but give limited opportunities to optimize functionality; and variable frequency drives which provide more fine-tuning possibilities but can be complicated to install and difficult to optimize. SmartRun solves this issue by combining the advanced functionality of a drive with a simple intuitive interface," Fredriksen said.

The Flygt Experior is available in modular pumping system packages that ensure it can be customized to meet specific applications. For more information on the system, visit: http://www.flygt.com/en-us/Pumping/Experior.

Earlier this year, ITT announced its intention to spin off its Water and Defense businesses into separate publicly traded companies. The new water company, Xylem, provides products and technologies for water and wastewater; residential and commercial water; analytical instrumentation; and flow control. These water businesses generated 2010 revenues of $3.2 billion.
