Energy-optimized pumps feature integrated MLE motor to simplify commissioning, startup
DOWNERS GROVE, Ill. — First introduced at the 2014 AHR Expo, the Grundfos LCSE split-coupled end suction pumps are now available for sale in the United States. Available in 21 different models, the fully integrated, intelligent LCSE pumping system features the MLE variable speed motor in ranges from 3 to 30 horsepower (HP) in 3500 revolutions per minute (RPM) and 3 to 25 HP in 1800 RPM. Speed control pumps like the LCSE offer energy savings of up to 50 percent.
“Our integrated pump systems help our customers meet the energy challenge now by improving system performance and reducing lifecycle costs,” said David McLean, Vice President Business Development for Grundfos Commercial Buildings. “The intelligent MLE motor system greatly simplifies pump commissioning and startup for each of the models. As a pioneer of innovative pumping solutions, Grundfos is dedicated to developing the highest quality pumps and pumping systems while at the same time contributing to a better quality of life and a healthier environment.”
Ideally suited for new commercial HVAC/R applications and retrofits, the LCSE offers one sole supplier for pump, motor and drive, resulting in reduced planning, purchasing, installation, wiring and commissioning costs.
The LCSE offers a systems approach, which, through intelligent technology, adapts precisely to current demand to deliver performance, energy efficiency and reliability. The integrated, energy‐optimized MLE system consists of a system controller, variable frequency drive (VFD) and standard asynchronous motor all in one, and can be fitted with loose sensors. Both are configured and interfaced at purchase, and their plug-and-pump design results in quick and easy installation.
In addition, the LCSE features a footprint 35 percent smaller than that of a frame-mounted design. Its design allows for rapid mechanical seal access without motor removal. The unique design requires no baseplate grouting or coupling alignment in the field. The LCSE also features Grundfos GO technology, which allows building managers to remotely control and monitor the pump from a smart phone or tablet. The GO also facilitates installation and commissioning.
Product CSI specifications, range charts, brochure, pricing, and selection of the products will be available on www.grundfosexpresssuite.com. The LCSE is available for six-week delivery. For technical details, see the product page.
