Armstrong Fluid Technology has announced the launch of 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 said 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% compared to pumps supplied with a loose variable speed drive, said the company in a statement.
 
Together with new more efficient pump hydraulics, the new 1 to 10hp pumps can save an additional 20% compared to competing integrated products with induction motors, said the statement.
 
Other features of the new Design Envelope outdoor pumps include:
• Cover to protect touchscreen user interface from dirt and sunlight
• Overhead weather shield protects motor fan from ice seizures
• Factory-tested Nema 4X rated controls are TL approved
• Available Parallel Sensorless control provides additional energy  
   savings through best-efficiency staging
• Available Pump Manager service provides pump performance 
   tracking along with alerts, alarms and data storage
 
"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," noted Zeljko Terzic, the Global Offering Manager, Pumps. 
 
"Our new Design Envelope pumps feature integrated controls for a reduced footprint and substantially reduced installation costs," he added.-TradeArabia News Service
