Armstrong Fluid Technology
About
Armstrong Fluid Technology is a global manufacturer of HVAC fluid-flow equipment and intelligent pumping systems, founded in 1934 by Samuel Allan Armstrong and headquartered in Toronto, Canada. With over 1,200 employees and eight manufacturing facilities across four continents, Armstrong combines pumps, heat exchangers, controls, and monitoring into integrated building energy solutions for commercial, institutional, and industrial applications. The company's defining technology platform is Design Envelope, which integrates variable-speed drives, permanent-magnet motors, and sensorless control into pump units to achieve up to 75% energy savings over conventional constant-speed installations—amounting to over $311 million in documented savings since 2007. The Design Envelope 4300 series offers pipe-mounted vertical in-line pumps ranging from 0.33 to 1,250 hp with flows up to 25,000 USgpm, while the 4280 series provides base-mounted end-suction pumps from 1 to 10 hp. Multi-pump configurations include the 4322 and 4372 Tango units for parallel pumping or redundancy, and the 4380 and 4392 dualArm pumps for space-saving installations. Armstrong also manufactures conventional pumps including the 4600 horizontal split-case series, 4700 vertical multi-stage pumps, 4030 end-suction base-mounted pumps, and circulators including the Design Envelope Compass H and R variable-speed models. Supporting products include booster packages, plate and shell-and-tube heat exchangers, fire protection pump systems, Suction Guide multi-function fittings, and Flo-Trex combination check/shutoff/flow-measurement valves. The Active Performance Management platform provides cloud-based monitoring and predictive maintenance.
