An oil diffusion pump has a relatively simple structure which provides the ease of maintenance and has a good maintainability. It is less expensive and can achieve a high pumping speed at a low cost.
Oil Diffusion Ejector Vacuum Pump PBL Series
ULVAC's oil diffusion ejector pumps are generally used in industrial processes to provide high pumping speed. They are particularly well-suited for use in metallurgy, plastic coating and chemical manufacturing, where large quantities of gas have to be pumped away as quickly as possible.
Oil Diffusion Vacuum Pump ULK Series
ULVAC's diffusion pumps ULK Series have been developed not only for superior performance, but also for extremely low operating cost.
