JC Vacuum Pump Oil
Product number:VP46 VP68 VP100 VP150 VP220
product description:
JC Vacuum pump oil is made up of high quality mineral oil and a variety of selected additives. It is suitable for sealing and lubrication of all kinds of mechanical vacuum pumps. The product is divided into 46, 68, 100,etc,according to the kinematic viscosity at 40 degrees C.
characteristics:
The lower saturated vapor pressure can maintain high vacuum and faster pumping rate at higher ambient temperature.
Good oil and water separation ability, excellent foam resistance and oxidation stability.
Good sealing and lubricity.
Recommended use:
It is suitable for high speed rotary vacuum pumps in electronics, lighting, chemical, refrigeration and air conditioning industries, as well as the sealing and lubrication of the gear in Roots vacuum and bearing transmission system. For example, large direct connection vacuum pump, small slide valve type vacuum pump, vacuum smelting, vacuum coating and piston type vacuum pump cycloidal vacuum pump, etc.
