HFV-серии Вакуумный насос масла

Proformance 1.HFV-A seriesoil has a wider temperature range compared to theM series. 2. Better anti-wear ability to reduce interface wear when compressing. 3. Srperior oxidation stability, reduce the interfacial abrasion, delay the operation life of the pumps 4.Desirablefoam characteristics to reduce wear due to overflow and interruption of work fluid 5. HFV-A series oil keeps pumps running at high vacuum degree,with a much longer service life.Application1. Applicable to poorworking conditions and keeping good vacuum degree under conditions of high timperature,high pressure or high load. 2. Can beapplied to various domestic and foreign vacuum pumps such as the British Edwards,German Leybolkd,French Alcatel and Japanese Ulvoil.Typical dataItem / ModelHFV-A100HFV-A200HFV-A250Kinematic viscosity (40),mm2 /s41.450.661.274.890110Viscosity Index105105105Flash Poin225240250Pour Point-10-10-10Demulsibility(40-40-0)ml,min541010-82--10Foam property2480/080/080/093.550/050/050/0Later 2460/060/060/0Extreme pressure ,kPaDifferential pressure2.0 ×10-52.0 ×10-52.0 ×10-5Total pressure2.0 ×10-42.0 ×10-42.0 ×10-4
