Name: HFV-M High Vacuum Pump Oil Model: HFV-M Brief: Superior ability of emulsion resistance and oil-water separation when exposed to water vapor.

详细介绍

Performance

※ Fine purification, small amount of aromatic and gum.

※ High flash point and viscosity index to keep stabilization of vacuum degree at high temperature.

※ Superior ability of emulsion resistance and oil-water separation when exposed to water vapor.

※ Good oxidation stability,inhibition of grease stain and coking and extending the oil-change intervals.

Application         

※ HFV-M series is applicable to various domestic and foreign mechanical vacuum pumps.

※ HFVM100 is suitable for sliding vane rotary vacuum pump and roots pump with volume flow rate of 4 Liter,esp.for refrigerating industry with large pumping.

※ HFVM200 can be applied to sliding vane rotary pump sith volume flow rate from 5 Liter to 30Liter,esp.in picture tube and illuminating industry.

※ Applicable to industries such as refrigeration,electro-vacuum,distilling,

cryodesiccation,biology,chemical,etc.

※ Be equivalent to Japan Moresco MR vacuum pump oil.
