Water for injection (WFI) is commonly used in the pharmaceutical process industry, however the very low conductivity of the media can cause electro-chemical corrosion of the Silicon Carbide when used in centrifugal pumps and other high-speed equipment. As a result, end-users were suffering stochastic life time from the mechanical seals applied. From extensive testing in the Roplan test lab with different Silicon Carbide qualities in WFI, a best performing Silicon Carbide quality could be verified. By solving Electro-chemical corrosion in high-speed equipment, stochastic life-time has been reduced to a marginal problem.
