Customized Gear Shaft For Gear Pump In Material Of SSiC Or ZrO2
Description of gear shaft:
Because of the excellent properties of silicon carbide and zirconia material, especially their good chemical stability and corrosion resistance, they are widely used in the industries with special working condition. Our company had stably supplied ceramic step sleeves for European pump companies, like Germany DST and Germany DRE for many years, so we have abundant experiences in production of gear shaft. Welcome your inquiry.
