Ceramic Rotor For Rotor Pump In Material Of Silicon Carbide Or Zirconia
Description of ceramic rotor:
We can manufacture SSiC or ZrO2 ceramic rotor which are used in rotor pump. Rotor pump can be applied to transmit a variety of complex fluid media. Because of the good resistance properties of silicon carbide and zirconium oxide, the rotor pump fitted with our ceramic rotor can work better in corrosive condition and higer temperature.
