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:
