ULVAC Oil Diffusion Ejector Vacuum Pump PBL Series

(Please note this item has a 8 - 10 week lead time) 

 

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.

 

The oil diffusion ejector pump consists of a pump body, heater and 3-stage jet stack assembly. The working fluid is heated in the boiler, vaporized and ejected out of each stage of the jet stack at high speed. Gas molecules on the high vacuum (inlet) side of the pump are captured in the jet vapor stream and are transported from the upper to the lower jet stages which compresses them in the process. These pumped gasses are then exhausted through the outlet port to the backing pump. The vapor stream from the jet stack is cooled and condensed on the inner walls of pump housing and returned to the boiler.
