Polished High Precision Zirconia Ceramic Pump Cylinder Piston
Polished High Precision Zirconia Ceramic Pump Cylinder Piston
Description:
Aluminum oxide (Alumina) has an extensive application due to its versatility and low cost of material than other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion. Our factory produces a selection of purity of alumina from 95% to 99.8%, all of the ceramic parts we supplied are with a dense body via dry pressing, hot pressing, ceramic injection molding, and ISO pressing.

Advantages:
1. Ceramic plunger adopts high-performance technical ceramic material, which has high hardness, wear resistance, high temperature resistance and corrosion resistance. Ensure material performance is reliable.
2.The microporous structure obtained by the unique working method of the ceramic plunger working surface has self-lubricating effect, which changes the mechanism of sliding friction and lubrication of the conventional plunger pump.
3.The inner cavity surface adopts a fluid structure with no dead angles or grooves. The surface of the inner cavity is matched with the surface of the plunger by an advanced high-precision internal and external cylindrical grinding machine to the mirror surface, and the outer surface is vibrated and polished to facilitate cleaning and disinfection.
4.The structure of the pump body is finely sealed with the product structure for easy disassembly.
5.These products have been tested for corrosion resistance and acid and alkali resistance, and their indicators have reached the level of similar foreign products.
Application:
1.Ceramic shaft,sleeve for different pump.
2.Ceramic plunger for high pressure cleaner.
3.Wearlessness,resistant acid-base and high intensity ceramic assembly apply to petroleum,chemical industry.
