Description of the ceramic seal face

Alumina ceramic seal face is characterized by its extremely high strength, wear resistance, low friction, and chemical stability. The outstanding surface quality (diamond polished surface )on both sides makes it sealing performance as desired. Due to alumina's versatile features, alumina ceramic seal ring could work with various severe service environments well, even if under hot strong acid and alkali, high temperature, high pressure, high voltage / current status. It has a super long service cycle in comparison with metal mechanical seals and reduces the time of maintenance 
The ceramic seal face plays a key role in water, oil, gas sealing system, we always ensure that we manufacture best-quality products through strict quality control in every process, we introduced KPI into our manufacturing flow chart and keep all batches with consistent dimensions. 
With over 15 years of manufacturing experience for ceramic seals, we have been supplying a variety of standard components, also we support various customized needs per your technical drawings, specification or practical samples.99% 99.5% 99.8% Alumina Ceramic Components 0.002mm Smooth Flatness 0
 
 
Application of ceramic seals:
Ceramic seal discs are widely used in a variety of water faucet, water tap, sanitary sealing system, regulating system,  sealing valves, water /oil/gas pump and so on.

Packaging proposal and transportation solutions

1. We will keep the ceramic parts inside the inner package to be fixed without moving, then it will prevent them from collision each other, to avoid any cause any chippings during transportation.

2. In addition, the inside of the outer carton will be filled with sufficient protective kinds of stuff.
