Ceramic plunger is one of the leading products of our company. The main materialswe use are alumina and silicon carbide, both of which are ceramic materials thatare of superior quality. By adding suitable amount of tenacity increased materialsto the ceramic or silicon carbide, and adopting isostatic press molding, andthen after the high-temperature firing, the ceramic plunger is finally finished.Ceramic plunger is now used with many top grade high-pressure plunger pumps at homeand abroad. It has the outstanding merits of high anti-wear ability, high hardness,high-tenacity, high anti-corrosion and low coefficient of thermal expansion.Its working life is as five to six times long as the metal plunger, and is sureto be an ideal substitute for the metal plunger. producing area:China
