The commonly used vacuum pump oil for SV rotary vane pump is 100# or 68# oil, but if the user’s local temperature is too low or it is used outdoors, it is recommended that the customer use anti-wear hydraulic oil, which can withstand low temperature, #46/ #68, and actually does not freeze at minus 30 degrees. , just buy a similar one. The number of oil refers to the viscosity. For example, the viscosity of No. 68 is 68. If the working temperature of the customer is relatively low, use oil with low viscosity, which is not easy to stick at low temperature.
