Armstrong Fluid Technology announced the availability of six new Design Envelope pump models engineered specifically for low-flow, high-head applications.

With the current emphasis on energy and cost savings in buildings of all types, there is a growing requirement for pumps that serve lower flow ranges. To meet this customer demand, Armstrong has added three new Design Envelope Tango models:

• 25-80 (1 x 1 x 3);

• 32-125 (1.25 x 1.25 x 5); and

• 40-125 (1.5 x 1.5 x 5).

The company has also introduced three new Design Envelope Vertical In-Line models:

• 40-125 (1.5 x 1.5 x 5).

Design Envelope industry-leading pumps feature on-board intelligence, connectivity and reporting capabilities. Contractors and maintenance professionals will also appreciate:

• Flow metering accuracy of +/-5% that optimizes the performance of the entire HVAC system;

• 29% more energy savings than standard variable speed pumps;

• Embedded Parallel Sensorless Pump Control for an additional 30% energy savings achieved through best-efficiency staging;

• Capability for parallel operation and redundancy allows system designers to select smaller pumps for even lower first costs;

• Easy switch from BAS to Sensorless control mode; and

• Availability of an outdoor-rated version – optional.
