New Grundfos COMFORT PM Recirculating Pump Uses AUTOADAPT to Cut Residential Energy Costs up to 85% When using the AUTOAD-
adapts to it.
APT mode, average run times are only 3 hours per day, yield- ing up to an 85 percent power and 48 percent heat/energy savings over conventional constant-speed circulators.
Grundfos COMFORT PM AUTO®
The new Grundfos COM-
FORT PM AUTO® range of residential circulating pumps set the standard for intelligent and energy-effi cient hot wa- ter recirculation through its AUTOADAPT function, which learns the household’s con- sumption patterns and then
The single phase, 115V pump motor yields up to 6.5 GPM and uses two tempera- ture sensors; one within the pump and another connected by a cable installed in the hot- water fl ow pipe.
Grundfos is the only manu- facturer to offer a variable- speed electronically commu- tated motor (ECM)-based cir- culator that uses an integrated logic algorithm to “learn” the varying energy-usage pat- terns of an application over time, enabling the software

to automatically determine the lowest possible operating effi ciency point to meet ever- changing demand. By con- tinuously fine=tuning power consumption and fl ow rates to meet the dynamic needs of the system, this AUTOADAPT function saves both energy and money.
The AUTOADAPT function is so powerful that eight out of every ten installations can rely on this feature to automatically select the optimal setting, with no additional human interven- tion. For the installer, that simply means plug and play and walk away.

nal product, the data matrix label – which includes the model and serial numbers, test performance data, date and time stamp – doesn’t print unless both pump and motor pass their tests. This process, currently used for the production of the 4-inch submersible pumps, is im- portant because it enables the installer to scan the product and understand how it is going to perform before they invest time and money to install it. “A great sense of pride and responsibility comes with knowing that each product can be traced to its origins and was as- sembled here in the U.S.,” said Foster.
BEYOND THE BUILD Xylem’s superior perfor- mance and quality test- ing are matched by the company’s training and educational offering for the residential and wastewater
market. The Seneca Falls facility hosts the Campbell Education Center and labo- ratory, which has educated thousands of people about Goulds Water Technology products and taught trou- bleshooting techniques for more than 30 years. The GWT Factory School,
as it’s called, was revamped in 2012, providing distribu- tors, dealers, engineers and other industry profes- sionals with hands-on expo- sure to the latest pumping technologies, and a suite of courses that span the GWT product line and related systems.
The lab comprises mo- bile demonstration units, network and Wi-Fi enabled equipment, LED TVs and configurable work stations for real-world experience in residential and wastewater pump systems. Comple- mentary to the interactive lab environment is practical education in the classroom outfitted with smart tech- nology. “We believe that invest- ment in education is critical to the success of our in- dustry,” said Tom Stephan, Manager, Goulds Water Technology Training. “Be- cause we provide a full sys- tem offering and have the ability to teach to specific residential applications, we are able train beyond the product.”
Education is also impor- tant to Xylem customers like Texas-based Whisenant & Lyle Water Services, which has been purchasing GWT pumps through Austin Pump and Supply for more than 15 years. “We’ve had a good working relationship,” said Pat Lyle, Vice Presi- dent and General Manager, Whisenant & Lyle Water Services. “Some of it is due to the fact that Goulds Water Technology goes the extra mile with education and taking people to where the pumps are produced, and seeing the people who produce them.” Tyler Sutliff, president of Whisenant & Lyle, agrees. “We are learning about technology that we’re using now as well as technology coming online in the future. Xylem is keenly focused on helping support our busi- ness, which, in turns, helps us grow our business,” Sut- liff said.
From concept and engi- neering to assembly, testing and installation, GWT prod- ucts continue to be produced with the conscientious pride of a workforce dedicated to quality, the credibility of a 150-year old company, and the high reliability of compo- nents and processes critical to ensuring an excellent pump ownership experience.
