Armstrong Fluid Technology recently launched the Design Envelope 4380 pumps — intelligent pumps with cloud-based active performance management. These pumps use Design Envelope technology to reduce pumping costs through demand-based operation and consume only the energy required.

The Design Envelope technology and advanced features of these pumps provide numerous benefits, including energy efficiency, low maintenance cost and high system uptime. These pumps are adaptable to design and building changes, future legislation and provide buildings with the lowest operational and embodied carbon. They represent a complete solution for heating, cooling and plumbing systems.

Intelligent pumps with cloud-based active performance management are designed to exceed U.S./Canada pump energy index regulations. The pumps have an advanced hydraulic design that supports industry-leading flow efficiency. The built-in parallel sensorless pump control saves up to 30% more energy, and Armstrong DEPM motor technology delivers an additional 6% to 20% efficiency, meeting IE5 efficiency standards. The control algorithm constantly reviews operating conditions and adjusts output to meet immediate flow requirements at minimum energy consumption.

The pumps are easy to maintain, and the mechanical seal can be replaced in 15 minutes without realignment, providing significant cost savings per unit. The system also addresses pump uptime/availability by offering a more efficient solution compared to conventional pump arrangements. Traditional systems employ a duty/standby approach to redundancy to ensure the design point is always met. This inflates the installed costs for equipment and labor and adds to the carbon footprint of the building. Armstrong’s intelligent pumps with cloud-based active performance management provide a more modernized approach. With a unique dual-pumping configuration, pumps and motors are selected from a range of sizes to achieve a level of redundancy that matches the requirements of the application.

The pumps feature a performance range of 15 to 450 U.S. gpm (1 to 28 ll/s) flow; 10 ft to 160 ft (3 m to 48 m) head and temperatures of up to 250° F (121° C). Materials of construction include ductile iron e-coated casing, stainless steel impeller, and a sintered silicon carbide mechanical seal.
