What Ateliers de Construction de Herstal SA does

Ateliers de Construction de Herstal SA (trading as ACH or AC HERSTAL) is a privately held Belgian industrial firm founded in 1953 and headquartered at Rue Hayeneux 148, 4040 Herstal, Belgium, with a secondary operations office in Nairobi, Kenya. The company designs, manufactures, installs, and commissions centrifugal pumps and complete electromechanical installations for fluid handling, with a core focus on water distribution, drinking water treatment, wastewater treatment, and industrial water systems. Its pump portfolio is custom-built for specialized industrial applications including water supply, palm oil processing and hydrocyclones, diesel engine cooling for marine and nuclear applications, mining, and slurry and mineral processing. The company also delivers turnkey water infrastructure projects covering engineering, installation, commissioning, operation, maintenance, and training for municipal, government, and industrial clients internationally.

ACH's technical platform is anchored by an in-house ISO 9906 Class 1 certified test bench (covering submersible and ground floor pumps) and an ISO 9001 certified quality management system, with pumping stations offered in prefabricated or concrete configurations across flow rates from 50 m³/h to 1,000 m³/h and pipe specifications DN 50 to DN 400 in cast iron or stainless steel 304L/316L. The company generates revenue through project-based industrial pump sales, engineering/installation/commissioning professional services, maintenance/repair contracts (including multiannual preventive maintenance), and pump training services, with project-specific custom quotes rather than public pricing. Go-to-market is direct enterprise field sales to municipal water utilities, government agencies, and industrial companies, supplemented by an international turnkey project delivery capability across Western Europe, Sub-Saharan Africa, and claimed presence in the USA, China, and Latin America. Customer concentration is project-driven, with named municipal and government contracts in Belgium (Durbuy, Beez, Waltzing), Ghana (Nsawam), and Kenya (Ithanga). The legal entity is a Belgian Société Anonyme (SA), described as family-run, with no parent company, institutional investors, or public listing disclosed.
