HFV-WS真空泵广泛的温度

Performance 1. Reasonable composition, stable chemical character for special gas 2. Properties of ultimate pressure,back stream rate and pumping rate are similar to silicon oil and ester oil.It is hard for residual gas to produce insulubility insulation film that will have effect on vacuum units. 3. Good oxidation stability,inhibition of oil dirt and coking,extending the oil-change intervals and saving costs. Application 1. Applicable to variety domestic and foreign mechanical vacuum pumps. 2. Applicable to wide timperature range from -25to100. 3. Can be appliedto special gases such asN2, NH3, H2, He,Ar, CO2, SO2, H2S,etc. Typical data Item / ModelHFV-WS 32HFV-WS 68Kinematic viscosity (40),mm2 /s28.8 35.261.2 74.8Flash Poin,(open cup)180200Pour Point-30-30Extremepressure,kPa Differentialpressure5.0 ×10-55.0 ×10-5Totle pressure5.0 ×10-45.0 ×10-4
