7. Sundyne
Sundyne traces its origins to 1957, when engineers at the Sundstrand Corporation aerospace division developed a high-pressure water injection pump for the Boeing 707. By 1962, the company had sold its first high-speed centrifugal pump to Shell Chemical, and compressor designs followed in 1965. Sundyne established its Colorado headquarters in 1968 and moved to Arvada in 1977, where the majority of its roughly 800 employees still work. The company specializes in integrally geared pumps, magnetic drive pumps, and gas compressors for chemical, petrochemical, hydrogen, carbon capture, renewable fuels, and power generation applications.
