Championx Corporation

A maker of specialty chemicals and artificial lift systems — pumps and related gear — that help oil and gas wells keep producing. The company was born from a 2020 merger between Apergy Corporation and the oilfield division of the cleaning-giant Ecolab, and its name reaches back to Champion Technologies, a firm founded in West Texas in 1953 to supply oil-treating chemicals to Permian Basin drillers. Today its operations also extend into digital production tools, and in 2025 it became part of the energy-services firm SLB.
