This product is made of high viscosity index in my factory quality products Qixing licensing 3# diffusion pump oil deep refining paraffinic base oil, rigorous molecular distillation and adsorption refining and thin film degassing process and the production.

This product is suitable for all kinds of vacuum pumps (including direct mechanical vacuum pump, vacuum pump) sealing and lubrication, also applies to the roots vacuum pump (mechanical booster pump) gear lubrication system.

This product is of high viscosity index, have good viscosity temperature properties, excellent lubricity, pump start easily, low energy consumption; has a lower vapor pressure, oxidation stability, a strong water separation excellent, limit can still maintain a high vacuum and high pumping speed in the use of the environment of high temperature.
