Ceramic Plunger Description :
Our ceramic plungers are made of high quality imported raw materials, cold isostatic pressing forming way , and assembled with stainless steel metal parts after high temperature sintering. As one of the main components of the plunger pump, the ceramic plunger is matched with the plunger sleeve. Ceramic Plunger is a shaft type with regular shape, accuracy dimension. Not only its shape and position accuracy are relatively high requested, especially its wear resistance and resistance to Corrosion are the most important properties. The performance of the metal plunger is much lower than that of the ceramic plunger. The ceramic plunger has high temperature resistance, wear resistance, corrosion resistance and impact resistance, which guarantees a longer service life.
It is widely used in various liquid pumps, metering pumps, high pressure pumps, mud pumps, etc.
