Original Edward vacuum pump oil Ultragrade 70

Original Edward vacuum pump oil Ultragrade 70Mainstream models: UL15, UL19, UL20, UL70 series, compatible with different types of vacuum pumps (such as E2M series mechanical pumps, GXS screw pumps, etc.). Packaging specifications: 1L, 4L, 5L drums, bottled in stock can be shipped directly. ‌Original Edward vacuum pump oil Ultragrade 70Product Technical Characteristics and Selection Suggestions 1 Steam pressure indicators: UL15 (5.8 × 10 ⁻⁶ mbar at 20 ℃), UL70 (2.1 × 10 ⁻⁷ mbar), excellent high-temperature stability. two Core function: Form a lubricating film to reduce mechanical wear. Seal the pump chamber to maintain vacuum level. Export frictional heat to prevent overheating. ‌56 3. Selection principle: It is necessary to match the working temperature of the pump body (UL70 is suitable for high load circulation systems).Original Edward vacuum pump oil Ultragrade 70Maintenance and Troubleshooting Guide 1 Replacement cycle: The standard cycle is 3000 hours (GV600 dry pump needs to replace the oil mist separator at the same time). When the oil turns yellow/black, it must be replaced forcibly. ‌‌6 2. Signs of deterioration: The solidification of oil sludge leads to an increase in operational resistance. Deep maintenance is required when the vacuum degree drops to 0.5Pa. ‌‌ 3. Key components: Regularly check the aging condition of the oil seal shaft sleeve (the main cause of oil leakage)
