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.
Features
- These pumps have maximum pumping speed at 10-1 Pa level.
- Stainless steel is used for the pump bodies of Model PBL-02 and PBL-04 in order to minimize outgassing of the pumps, eliminate corrosion and to ensure a long operating lifetime of the pump.
- The PBL Series are particularly well-suited for the use as an intermediate pump between an oil rotary pump, a mechanical booster pump and oil diffusion pump.
- The larger capacity pumps (PBL-06 - PBL-20) have the heaters directly immersed in the operating fluid for maximum thermal efficiency.

*1 The ultimate pressure by an ionization gauge in the case of coolant temperature 20 degrees Ceisius.
*2 The backing pump chooses it for the maximum throughput of the diffusion ejector pump,but,in consideration of time of
starting pressure,it is good to use a big backing pump.
*3 Please confirm other dimensions by CAD data placing in the ULVAC,Inc.website.
