Armstrong Fluid Technology has launched Design Envelope pumps that boast permanent magnet motors which are now 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 per cent 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 per cent compared to competing integrated products with induction motors.

Other features include:

• Cover to protect touchscreen user interface from dirt and sunlight;

• Overhead weather shield protects motor fan from ice seizures;

• Available Parallel Sensorless control provides additional energy savings;

• 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.
