I produced zirconia ceramic plunger products, which are characterized by: contact with the media and the surface are zirconia ceramic, plunger column and metal handle with mechanical connection, while ceramic pieces and metal handle between the filling adhesive , To prevent thread loosening. And the existing ceramic plunger ratio, with anti-off, reliable connection, high strength characteristics; while zirconia ceramic plunger life than metal plunger 10 times higher, but also can improve the life of sealed packing, with high resistance Wear, corrosion resistance, impact resistance characteristics. Widely used in petroleum, chemical, food machinery and other industries to use the piston pump.
