Advanced alumina ceramic plunger
Material: zirconia ceramic/alumina ceramic/ Si3N4 ceramic high Density: above 3.6~6.0g/cm3 High strength and very hardness. Long use time Max Working temperature Vickers Hardness: 1300 HV0.5 Flexural Strength: 1000 Mpa Color: White
Seamark ceramic can provide advanced ceramic plunger. High-strength and fracture toughness
High-hardness and density
Ultra-smooth surface, low-friction coefficient
Modulus of elasticity and thermal expansion
Coefficient similar to steel
2.Ceramic metal plunger
Compared with metal plunger, alumina ceramic plunger solved the problem of bad corrosion and wear resistance and short working life. Compared with existent ceramic plunger, our anti-pull-off alumina ceramic plunger solved the problem of easier pull off of metal from ceramic. The Plungers are connected with metal handles mechanically, and the viscose glue is filled between them to prevent the screw from getting loose.
3.Properties of alumina ceramic plunger
1)High Corrosion and wear resistance
2)Strong impact resistance
3)dilevers 10 times longer working life than metal plunger
4)They give a longer life to the sealed packing material
4.The application ceramic plunger
1, Ceramic shaft for aquatic animals equipment filter pump
2, Alumina Ceramic plunger for high pressure cleaner.
3, Wearlessness, resistant acid-base and high intensity ceramic assembly apply to petroleum , chemical and chemical industry.
4, Wearlesness, corrosion resistance parts apply to precision machine.
