Booth #24 to feature pumps with patented energy-saving AUTOADAPT™ technology

DOWNERS GROVE, Ill.—Grundfos will exhibit its high-efficiency, variable-speed circulators MAGNA3™ and ALPHA™ at the Oil & Energy Service Professionals (OESP) 2014 Road Show from May 12 to 13 in Mohegan Sun, Conn.

MAGNA3 and ALPHA offer much more than the ability to match pump speed to varying system loads. Both circulators feature a variable-speed electronically commutated motor (ECM) that uses a patented integrated logic algorithm, AUTOADAPT™, to learn the varying energy use patterns of an application over time, enabling the software to automatically determine the lowest possible operating efficiency point to meet ever-changing demand.


Boasting the highest energy-efficiency rating currently available for circulator pumps in North America, the MAGNA3 is at the absolute forefront of pump technology. It is an energy‐optimized, variable-speed wet rotor circulator whose adaptive intelligence cuts power consumption by up to 85 percent when compared with conventional circulators.

MAGNA3 features extremely low energy consumption, a flexible range of applications, easy installation and the most innovative functionalities on the market. From its improved hydraulics and rotor system to a built-in differential pressure sensor, every detail of MAGNA3 is designed to boost efficiency. It consumes 20 to 40 percent less energy than most models in the current MAGNA line, already a best-in-class energy-efficient circulator.

Easy to install, operate and maintain, the innovative MAGNA3 features easy interfacing with building management systems. Wireless connectivity enables handheld pump control, monitoring and reporting capabilities by Grundfos GO, a mobile toolbox app available on Apple and Android devices.


In addition to the ultra-efficient MAGNA3, Grundfos will also showcase ALPHA, the most compact circulator available in its class. Designed for circulating liquids in light commercial and residential heating systems, it features integrated electronics and software, permanent magnet motor design and flexible power cord connection.

In addition, ALPHA features one-touch operation, real-time display and an integrated processor that provides the intelligence to measure and adapt to changing system conditions. ALPHA is available in cast-iron pump housings for closed systems or stainless steel housings for open or domestic hot-water systems.

By continuously fine tuning power consumption and flow rates to meet the dynamic needs of the system, AUTOADAPT saves both energy and money for MAGNA3 and ALPHA users. The AUTOADAPT function is so powerful that eight of 10 installations can rely on this feature to automatically select the optimal setting with no additional human intervention. For the installer, that simply means plug and play and walk away.

“Our customers demand more, so we endeavor to deliver products that not just meet but exceed their needs,” said Terry Teach, business development director for Grundfos Domestic Buildings Services. “The MAGNA3, ALPHA and AUTOADAPT are all prime examples of pump technology made smarter and simpler. Our customers really appreciate how easy it is to utilize this advanced technology.

Utility Rebate Programs

Grundfos’ ALPHA and MAGNA pumps have been designated to participate in Efficiency Vermont’s High-Performance Circulator Pump Program, which promotes the installation of high efficiency pumps in Vermont homes and businesses. In addition, the ALPHA is part of Energize Connecticut’s High Efficiency Furnace, Natural Gas Boiler & Boiler Circulator Pump Rebates, which incentivizes the replacement of standard efficiency heating equipment with high efficiency alternatives. 

OESP Road Show attendees can learn more about the MAGNA3 and ALPHA, as well as related utility rebate programs, in Grundfos’ booth #24.
