JK Oil Diffusion Pump System aims for high vacuum pumping, which can reach around 10-2–10-4 Pa. The whole system equipped with main oil diffusion pump, valves, water-cooling baffle, pipe, and mechanical pump (a system of roots-pump). Since the improvement of the main pump and baffle, this system’s pumping capacity in low vacuum has been highly increased.
The main advantage of this system is its high pumping speed (from 190L/s to 49,000L/s) and long-term continuous working stability.
JK series system is widely applied in high tech field, such as electric, chemistry, metallurgy, aviation, aerospace, material, bio-medicine, A-energy, universe exploration, etc. Besides, there are still many other normal industries are using this system as well, such as various vacuum furnance, vacuum coating machine, vacuum freezing or drying system.
