Alumina Ceramic Bearings and Rod 95% Alumina Direct Current Motor Circulation Water Pump Component Abrasion Resistance
The Dimensions of the ceramic shaft is φ14*L130mm, whose material is 95% Alumina or Aluminum Oxide, Al2O3. And its color white.
Alumina ceramic shafts have the properties below:
So, it is usually applied as pump components instead of metal shafts in variant pumps like micro pump, shield pump, circulating pump, centrifugal pump, impeller pump, magnetic drive pump, ground source heat pump, aquarium pump, fountain pump etc.
Ceramic is a non-metallic, inorganic, temperature- resistant material that is at least 30% crystalline and is difficult or impossible to dissolve in water. As demands for ceramics performance are higher, the recipe for 95% alumina is also changed and improved so as to improve its friction resistance property, which makes circulating pumps last longer time.
