Armstrong Fluid Technology has announced a new version of its Design Envelope pump to serve light duty installations where the available power is single phase.

“Many light-commercial and residential buildings use single phase power and some mechanical rooms ‘step down’ three phase power to make single phase power available,” said David Lee, Program Manager, Product Development, Armstrong Fluid Technology. “These new pumps provide a practical and economical solution for those installations.”

The new Design Envelope pumps are now available for use with single phase power (200-230V) from 1/3 to 2hp and, for increased reliability, are built to a design standard carried over from commercial pumps. In addition, because the mechanical room piping for light-duty fluid-flow applications is often installed vertically, these new single-phase pumps can be installed and operated in vertical piping.

As with all Design Envelope pumps, the technology is built around a demand based intelligent control solution that:

• Models equipment and system behavior
• Monitors actual system conditions
• Dynamically adjusts equipment operation to match system demand
• Is designed to provide the highest energy efficiency and lowest installed and operating costs.
