Ceramic pump is made from modern engineering ceramic materials and it adopts ceramic metal bonding, welding , assembling and sleeve assembly molding technology . It has been widely used in medical equipment , environmental engineering , petrochemical and other industries.
Material:
Alumina Ceramic, Zirconia Ceramic, 316L Stainless Steel
Product Characteristics :
( 1 ) using high-performance technical ceramic materials with high hardness , wear resistance, high temperature resistance , corrosion resistance and other properties. Ensure reliable material properties .
( 2 ) the plunger have microporous tissue resulting from its processing methods and obtained self- lubricating , changing the mechanism of the traditional piston sliding friction and lubrication .
( 3 ) the use of the fluid cavity surface structure, no corners, grooves. Inner surface and the plunger are using advanced high-precision surface grinder and are processed to mirror, outer surface is vibratory polishing , easy cleaning and disinfection.
( 4 ) the structure of 316L stainless steel with pump seal , easy removal .
( 5 ) These products have gotten through safety testing of corrosion resistance and acid degree, the indicators have reached the level of similar foreign products .
( 6 ) the shape and size of the design and processing according to user needs .
