99% Plunger Zro2 Ceramic Piston Roller for Pump
Description:
Alumina ceramic is the most mature of the engineering ceramics,
offering excellent electrical insulation properties together with
high hardness and good wear resistance..The ceramic plunger adopts
the ultra-hard wear resistance of modern engineering ceramic
materials, and can be assembled by ceramic metallization bonding,
welding, inlay and socket technology. It is an ideal substitute for
similar metal pumps and has been widely used in medical equipment,
environmental engineering, petroleum, chemical and other
industries.

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.
