Product characteristics:
- Ceramic plungers are made of high-performance ceramic materials, which have the advantages of high hardness, high wear resistance, high temperature resistance, corrosion resistance and no pollution to materials.
- Among various metering pumps, ceramic pumps have the highest accuracy, which can reach ±3%, and maintain long-term stability and high repetition consistency.
- The micro-porous structure of ceramic plunger working face obtained by unique processing means has self-lubricating effect and no sealing ring is needed.
- The surface of cavity and plunger is machined into mirror by advanced high-precision internal and external grinder. The surface of cavity is made of fluid structure without dead angle and groove, which is convenient for cleaning and disinfection.
- The pump body structure is made of 316L stainless steel, which is connected with ceramics through a specific process.There are no other impurities and it is easy to disassemble.
The product has been tested for corrosion resistance, acid and alkali resistance and safety performance
