Armstrong Fluid Technology’s Design Envelope pumps with permanent magnet motors up to 10 hp are now available in NEMA 4X/IP66 rated versions for outdoor installation.
The new pumps feature advanced performance mapping technology and load-limiting logic and reduce energy consumption by up to 30% compared to pumps supplied with a loose variable speed drive. Together with new more efficient pump hydraulics, the new 1–10hp pumps can save an additional 20% compared with similar integrated products with induction motors.
Other features of the new Design Envelope outdoor pumps include a cover to protect the touchscreen user interface from dirt & sunlight and an overhead weather shield which protects the motor fan from ice seizures. The pumps’ factory-tested NEMA 4X rated controls are also TL approved. Also available is parallel sensorless control which provides additional energy savings through best-efficiency stagingand the Pump Manager service, providing pump performance tracking along with alerts, alarms and data storage.
Zeljko Terzic, Global Offering manager, Pumps, said: “Our new Design Envelope pumps feature integrated controls for a reduced footprint and substantially reduced installation costs.”
