New outdoor pumps can reduce energy consumption by as much as 30%

“The conventional approach to rooftop and outdoor pumps is to install variable frequency drives (VFDs) in a central, outdoor-rated control panel, separate from the pumps. This adds unnecessary costs and requires a larger footprint” says Zeljko Terzic, Global Offering Manager, Pumps, with Armstrong Fluid Technology.

“Our new Design Envelope pumps feature integrated controls for a reduced footprint and substantially reduced installation costs.”

The new Armstrong Fluid Technology Design Envelope pumps with permanent magnet motors are now available as NEMA 4X/IP66 rated units for outdoor installation.

The new pumps feature advanced performance mapping technology and load-limiting logic, and they reduce energy consumption by as much as 30% compared to pumps supplied with a loose variable speed drive.

Together with new more efficient pump hydraulics, the new 1-hp up to 10-hp pumps can save an additional 20% compared to competing integrated products with induction motors.

Other features of the new Design Envelope outdoor pumps include:

  • Cover to protect touchscreen user interface from dirt & sunlight
  • Overhead weather shield protects motor fan from ice seizures
  • Factory-tested NEMA 4X rated controls are ETL 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
