Our Story
Established in 1979 by Mr. A. Wischnewski, ASW Engineering began as a trusted importer of hydraulic and mechanical equipment for the mining and petrochemical sectors. From the start, the company built a reputation for reliability and technical excellence — a standard we continue to uphold today as a leader in the supply of mechanical and rotating equipment
In the early 1990s, our growing footprint in the water and wastewater sector led to the creation of a dedicated Water Treatment Division. This division specializes in supplying advanced equipment and delivering turnkey solutions for potable water treatment plants across the region.
Today, ASW's client base spans international organisations operating throughout South Africa and the African continent. This evolution has positioned us as a truly continental leader in industrial pumping, filtration, and engineering solutions.
