DPO 702 is offered as a DC 702 type equivalent performance-grade diffusion pump oil for users who need a practical replacement option for DC 702 applications. It is suitable for many diffusion pump systems where 702-grade oil is required, subject to pump compatibility and process conditions. Customers should compare the technical data sheet, certificate of analysis and equipment manual before replacing any existing oil. For critical research, coating or furnace applications, technical confirmation is recommended before switching from the original oil grade. 2 ) Can DPO 702 be used in PVD coating machines? Yes, DPO 702 can be used in diffusion pump systems connected to PVD coating machines, provided the oil grade is suitable for the pump model and process requirement. PVD coating systems usually require stable high-vacuum performance to support coating quality and process consistency. Before using DPO 702, the old oil should be drained properly and the pump should be inspected for contamination or carbon deposits. For best results, follow the pump manufacturer’s oil filling quantity, operating temperature and maintenance instructions. 3 ) Is DPO 702 suitable for vacuum furnace applications? DPO 702 is suitable for diffusion pumps used in vacuum furnace and heat treatment applications where a 702-grade diffusion pump oil is required. Vacuum furnaces often operate in demanding environments, so oil condition, pump cleanliness and cooling efficiency are important for stable performance. Before filling DPO 702, check the furnace vacuum system requirement and confirm compatibility with the existing diffusion pump. Regular oil inspection is recommended because contaminated or thermally degraded oil can reduce pump efficiency and affect the vacuum level. 4 ) How do I know when diffusion pump oil needs replacement? Diffusion pump oil may need replacement when pump-down time increases, ultimate vacuum becomes poor, the oil looks dark or thick, or contamination is visible inside the pump. Burnt smell, carbon deposits, frequent process contamination or unstable vacuum performance can also indicate oil degradation. In high-vacuum systems, oil quality directly affects pumping efficiency and chamber cleanliness. Regular inspection, proper cooling, correct heater operation and timely oil replacement help maintain stable diffusion pump performance and reduce the risk of downtime. ————————————————————————————————————
