Improving pump materials for harsh environments

Pumping corrosive fluids containing abrasive solids is a challenge. Sulzer can adapt pumps to such requirements by making the ideal choice of hydraulics and seals and by improving the materials used to produce the pump. Because it has its own foundry, Sulzer can offer materials that are not easily available on the market. The company has developed a specific heat treatment procedure for steel that improves wear resistance, while leaving corrosion resistance nearly unchanged
