Alumina ceramic plunger
  • Product Details

Product Introduction

Alumina ceramic plunger is a kind of engineering ceramic used in industrial ceramic plunger, which has the advantages of high melting point, high hardness, good insulation performance, good chemical stability, etc., and is widely used as high temperature structural materials, wear-resistant materials, electrical insulation materials and chemical corrosion resistant materials.
Alumina ceramic plunger is an ideal alternative to similar metal pumps, because the metal material is more easily corroded in use, while the alumina ceramic plunger has a high degree of corrosion resistance, in addition, the ceramic plunger in the production of modern engineering ceramic materials, so it also has ultra-hard wear resistance, has been widely used in medical equipment, environmental engineering, petroleum and chemical industries

We can provide customized services according to the drawings

The surface roughness of alumina plunger can reach Ra0.2um

It can be used in the environment up to 1650 ℃

The hardness is as high as 15.7Gpa, very wear-resistant

Other characteristics: high electrical insulation, strong corrosion resistance, high biocompatibility

We can do OEM and OBM according to you drawing and requires

Product Details


1.It has high hardness, wear resistance, high temperature resistance, corrosion resistance and other properties.
2.The metal pump needs to add lubricant in order to reduce friction when it is used, but the working face of the ceramic plunger adopts a unique processing method, so that the surface of the ceramic plunger can obtain a microporous structure, this micro-controlled block has a self-lubricating effect, so it can effectively change the principle of sliding friction and lubrication of the traditional plunger pump. Reduce the adverse effects of lubricants.

1. The inner cavity adopts fluid structure. The surface of the inner cavity of the alumina ceramic plunger adopts a fluid structure, so that there are no dead corners and grooves in the entire inner cavity of the plunger. Moreover, the surface of the inner cavity and the surface of the plunger are processed to the mirror using advanced high-precision internal and external cylindrical grinding machines, and the external surface is buffed by vibration, so that it can be cleaned and disinfected more easily after use.
