Introduction Alumina ceramic plunger piston
Alumina Ceramic plunger piston work exceptionally well in wear-resistance, high temperature, saltwater, chemical, and metering applications. It has the advantages of super hardness, high wear-resisting, good corrosion resistance resistant acid-base, high intensity, high temperature tolerance, high mechanical strength and so on. It is widely used in various mechancal field.
The Ceramic Plunger For Pump Parts is made of high-purity ceramic raw materials, which are formed by dry pressing or cold isostatic pressing, high-temperature sintering and precision machining.
Ceramic Plunger For Pump Parts can work in the acid and alkali corrosion conditions, high toughness and low friction coefficient, high pressure environment for a long time, and the maximum temperature to 1800 ºC (3272ºF)…
