ТУ У 23.2-30802090-031:2006 Vacuum oils Agrinol VМ are utilized as working liquids for mechanical vacuum pumps. Agrinol VМ-1 Oil is used as a working liquid in high-vacuum steamjet pumps BN-3 which work at the end vacuum from 1·10−3 to 1·10−6 mm of mercury. Agrinol VМ-3 is used as a working liquid in high-production oil-vapor booster pumps which work at the residual pressure from 1·10−2 to 1·10−4 mm of mercury. Agrinol VМ-4 Oil is used as a working liquid in mechanical vacuum pumps with oil seal.Agrinol VМ-5 Oil is used as a working liquid in high-vacuum steamjet pumps which work at the residual pressure from 1·10−3 to 1·10−7 mm of mercury. Agrinol VМ-6 Oil is utilized as a lubricating material and seal for piston fore-vacuum pumps which work at the residual pressure up to 1·10−3 mm of mercury. Agrinol VМ-11 Oil is used as a working liquid in high-production oil-vapor booster, auxiliary, steamjet and special fore-vacuum pumps. Guarantee period of storage – 5 years from the day of manufacture.
