A Firm Stance Against Corrosive Environments

Sulzer develops heat treatment procedure to strengthen pumps.


Published:

Pumping corrosive fluids containing abrasive solids is a challenge. To face this challenge, Sulzer has developed a specific heat treatment procedure for steel that improves wear resistance, while leaving corrosion resistance nearly unchanged.

There are several pumps that can operate in corrosive and abrasive environments, such as chemical or metal processes and wastewater treatment. To ensure high reliability, research and development in the fields of fluid mechanics and materials technology, as well as detailed knowledge of the applications and operating conditions, are essential, Sulzer said.

Hydroabrasive wear and corrosion can significantly reduce the lifetime of pump components. One possibility to optimize operational life in such aggressive surroundings is the use of specially adapted hydraulics or seals. Furthermore, the selection of appropriate materials is the key to ...
