Ceramic plunger pumps, including plunger body with a connecting end, said plunger body's internal core body made of metal material, ceramic material of the shell in the external cladding of the core body referred to;contact between said core body and shell and set the sealant; set block header at the end of the plunger body. Plunger of the above technical solutions, the external ceramic material coated on the metal core body made of, its wear resistance than 5-10 times the metal plunger, corrosion resistance of ceramics to solve the column plug corrosion problem, which greatly extended the life of the plunger to ensure the normal operation of piston pump can be in any adverse work environment. After the end of the plunger body set up block head, not only increasing the strength of the plunger, and closer integration between.Ceramic Plunger Details:Precision processing ceramic plunger, is widely used in petroleum, chemical, food, textile, medical and other industries, the product has a very high wear resistance, corrosion resistance, impact resistance, service life of the metal plunger - 10 times
