Hayward Holdings, Inc.
A maker of pool and spa equipment, Hayward designs the pumps, filters, heaters, lights, and automation systems that keep residential and commercial pools clean and running. It began in 1925 as a small Brooklyn machine shop making industrial valves, then took its modern form in 1964 when Hungarian immigrant Oscar Davis bought it and shifted production to corrosion-proof plastic — a move that produced the long-lived Super Pump and made the brand a fixture at backyard pools everywhere.
