99% Alumina Ceramic Piston Inferior Pump Component Wear Resistance High Hardness
Introduction
Ceramic, a non-organic material with much higher hardness than metallic parts, is a major engineering material. It offers a combination of good mechanical properties and electrical properties leading to a wide range of applications.

Alumina ceramic plungers, are formed by isostatic pressing or dry pressing technology. Grinding and polishing provide a uniform working surface for a stable performance. Through long operation, there is no leakage or just low leakage because of the high wear resistance of alumina ceramics. The alumina material complies with different drinking water regulations including certification for use up to 85° for German KTW, United Kingdom’s WRAS and French ACS, also for NSF for food safety.
Suzhou Jingci Super Hard Materials Co., Ltd, has been working on production of ceramic pistons and plungers for nearly 18 years and has an outstanding manufacturing capability up to 60 thousand per month. Furthermore, striking machining capability is shown in the below table:
| OD tolerance (mm) | Concentricity (mm) | Straightness (mm) | Perpendicularity (mm) | Length tolerance (mm) | Roughness (mm) | Roundness (mm) | ID tolerance (mm) |
| 0.01 | 0.02 | 0.005 | 0.02 | 0.05 | Ra0.15-0.25 | 0.005 | 0.02 |
As for ceramic plunger, diameters from 3mm to 240mm and surface Roughness 0.25 can be completed.
Jingci is always developing new thoughts and ways on the production of ceramic parts so as to provide qualified and economic products for customers.
