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.
