Armstrong Fluid Technology has announced that its Design Envelope pumps with permanent magnet motors up to 10hp, are now available as NEMA 4X/IP66 rated, for outdoor installation.
The new pumps have advanced performance mapping technology and load-limiting logic and reduce energy consumption by 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 to similar integrated products with induction motors.
The new Design Envelope outdoor pumps have a cover to protect the touchscreen user interface from dirt and sunlight, an overhead weather shield protects the motor fan from ice seizures and the factory tested NEMA 4X rated controls are TL approved. Also available is parallel sensorless control and Armstrong’s Pump Manager service which provides pump performance tracking along with alerts, alarms and data storage.
Unlike the conventional approach to rooftop and outdoor pumps where VFDs are installed in a central, outdoor-rated control panel, Armstrong’s new Design Envelope pumps feature integrated controls for a reduced footprint and substantially reduced installation costs.
