99 Alumina Ceramic Plunger

99 Alumina Ceramic Plunger for Printing System 

The Alumina ceramic plunger is sliding  fit to the cylinder part ,  so the outside diameter tolerance is requested to be tight  to match with the cylinder .  The clearance between the piston and cylinder bore is 10 +6/-0 micrometer on the diameter .  The collar housing is made of 316 stainless steel material as it is more corrosion resistant and chemical resistant .  The plunger rod material is 99% alumina ceramic  which is wear resistant ,  high temperature resistance and can be used in harsh environment .

The ceramic plunger are widely used on various type of pumps . It is made of modern engineering ceramic materials with superhard wear resistance. It can be assembled by ceramic metallization bonding, welding, inlay and socket technology. It is an ideal substitute for similar metal pumps. Compared with metal plunger, ceramic plunger has the remarkable characteristics of rough appearance, low friction resistance, high temperature resistance and corrosion resistance. Its design service time is 3 years.

A series of alumina zirconia ceramic plungers produced by precision processing are widely used in petroleum, chemical, food, textile, medical and other industries.

The ceramic plunger has extremely high wear resistance, corrosion resistance and impact resistance. The matching accuracy between the shaft core and the outer sleeve of the ceramic plunger can reach 0.001mm, and the finish can achieve the mirror effect, so as to reduce the friction coefficient, greatly improve the service time of the plunger and improve the starting efficiency.

The ceramic plunger is formed by isostatic pressing to ensure the consistency of density, so that it will not crack due to the doubt of density in work. The surface is finely polished with diamond to minimize the surface roughness, so as to add lubricity and durability.

It is another high-tech product developed according to the disadvantages of poor corrosion resistance of metal column plug, short service life of piston pump used in petroleum, chemical industry, food machinery and other occupations, as well as the current situation of unreliable combination and simple falling of existing ceramic plunger.

The utility model is characterized in that the contact surface with the medium and the working surface are zirconia ceramics, the plunger column and the metal handle are mechanically combined, and the adhesive is filled between the ceramic parts and the metal handle.

Avoid loose threads. Compared with the existing ceramic column plug, it has the characteristics of anti falling, firm combination and high strength.
