Traditionally, pump manufacturers used SiC (silicon carbide) for bushings and bearings in these pumps because of its high hardness and ability to withstand abrasive wear in solid media. Since the early 1980s, OEM pump manufacturers have been using sintered SiC bearings for the stationary and rotating components of tubular casing pumps.
Special Properties of Silicon Carbide High heat resistance 1,350 / 1,800 C. Corrosion resistance. Extremely high hardness. Sintered silicon carbide is created when pre-pressed and very soft SiC granulate is sintered at a temperature of more than 2,000 C
