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.

With no moving parts, these pumps are rugged and extremely reliable. They are very much like standard oil diffusion pumps, but are optimized to work at higher inlet pressures.
