Our synthetic blend Liquid Ring Vacuum Pump Oil is formulated from a vacuum distilled ultra-pure paraffinic hydrocarbon base stock to provide an extremely low vapor pressure vacuum pump lubricant. This non-foaming fluid has excellent water separation and provides protection against wear, rust and corrosion. These are extended life lubricants designed to function in re-circulating systems such as liquid ring vacuum pumps which are subject to severe temperature and environmental conditions. They are compatible with petroleum oils and PAOs.
