The technology used in manufacturing mechanical seals includes material development and surface treatment techniques developed by Neosen for seal face materials and corrosion resistant components. The Company offers various types of high performance metallic materials. For example, an alloy of cobalt bound tungsten carbide, a binder less tungsten carbide having high corrosion resistance, and heat treated alloys with increased strength and stability, are regularly supplied. In addition, we supplies sealing faces with minute spiral grooves resulting from their unique research on sealing surfaces and improved sealing techniques.
