Design Envelope pumps ... from Armstrong.

Armstrong Fluid Technology has launched its Design Envelope pumps that boast permanent magnet motors, which are now available Nema 4X/IP66 rated, for outdoor installation.

 A leading manufacturer of intelligent flow equipment including pumps, valves, heat exchangers and control solutions, Armstrong says the new model has key features such as advanced performance mapping technology and load-limiting logic.

 The Design Envelope pumps will also help clients reduce energy consumption by as much as 30 per cent compared to pumps supplied with a loose variable speed drive, says the company.

 Together with new more efficient pump hydraulics, the new 1 to 10 hp pumps can save an additional 20 per cent compared to competing integrated products with induction motors, says Armstrong.

The new Design Envelope outdoor pumps features a cover to protect touchscreen user interface from dirt and sunlight and an overhead weather shield, which protects the motor fan from ice seizures; and tracking along with alerts, alarms and data storage. The factory-tested Nema 4X rated controls are TL approved; while parallel sensorless control provides additional energy savings through best-efficiency staging. The Pump Manager service provides pump performance management technology.

“The conventional approach to rooftop and outdoor pumps is to install VFDs in a central, outdoor-rated control panel, separate from the pumps. This adds unnecessary costs and requires a larger footprint,” notes Zeljko Terzic, Global Offering Manager, Pumps. “Our new Design Envelope pumps feature integrated controls for a reduced footprint and substantially reduced installation costs.”
