Ceramic Plunger In Material Of Silicon Carbide+Brass For Reciprocating Pump
Description of Ceramic Plunger (SSiC pipe shaft+brass):
With the excellent corrosion resistance, wear resistance and other properties, silicon carbide (SSiC) is one of the best material for pump components. Our silicon carbide are made of highly purified, sub-micron silicon carbide powder. The atmospheric pressure solid phase sintering method at a high temperature of 2250°C are used to produce SSiC (Sintering SiC), so the free silicon and free carbon in the products are close to the theoretical values and can resist corrosion by hydrofluoric acid, which is the most excellent ceramic material with the best corrosion resistance among the known materials. Because of the good wear resistance of brass, the ceramic plunger fitted with brass can work well in reciprocating pump.
