Characteristics of ceramic plunger:
(1) The surface of the inner cavity adopts a fluid structure, with no dead corners or grooves. The inner cavity surface and plunger surface are processed to a mirror surface using advanced high-precision internal and external cylindrical grinders, and the outer surface is vibration polished for easy cleaning and disinfection.
(2) The pump body structure adopts fine sealing with the product structure, making it easy to disassemble.
(3) This type of product has undergone corrosion resistance, acid and alkali resistance safety performance testing, and its various indicators have reached the level of similar foreign products.
