High Precision Tank Valve 99% Alumina Ceramic Metering Pump
Product Description
We were specialized in the high precision ceramic pump ,ceramic plunger,ceramic cylinder sleeve.The material include alumina,silicon nitride and zirconia and so on.
Our ceramic piston pump is major using in the pharmaceutical machinery filling equipment.The filling volume from 0.5-500mL.
Because of the different filling machine's pinciple,different factory pump's structure ,size and packing will be different.So we can do according diferent factory's request.
The basicly surface roughness we can do is Ra0.2 even higher.The fitting gas( tolerance can reach min 5um,max 15um.Actually we doing it according to customers applications,
All in all ,we can make sure it will not leakage.
OUR ADVANTANGES
1.Adopt the technical materials with high performance----high hardness, abrasion resistance, high temperature resistance, corrosion resistance, which guarantees the reliability of materials.
2. Use special processing methods in the plunger piston working surface, and the obtained micro-pores have self-lubrication function, which changes the traditional theory that depends on sliding friction and lubrication.
3. Take the fluid structure in internal surface, no dead angle or groove. Use the advanced high precision internal and external cylinder grinder in internal surface and plunger piston surface and process to mirror surface. Conduct vibratory polishing in the external surface, which is convenient for cleaning and disinfection.
4. Adopt the 316L stainless steel to assist sealing, and this is convenient for disassembling.
5. Pass the safety performance test of corrosion resistance, acid resistance and alkali resistance. All indexes have reached the domestic level of same kind of products.
6. Appearance and size can be designed and processed according to the requirements of customers.nal surface, which is convenient for cleaning and disinfection.
