Oil Diffusion Ejector Pump ULK Series

Oil Diffusion Ejector Pump ULK Series

ULK-type oil diffusion pump is a compact high vacuum pump designed with high critical back pressure. It is used in a wide range of applications, from research to manufacturing line.

Features

  • Designed for large critical back-pressure
  • Extremely stable performance at pressures down to 10-2 Pa (10-4 torr)
  • Use hose flanges (except for vent flanges on ULK-04A and 06A)
  • Pumps can be cleaned easily (parts can be disassembled easily).
  • Come with mechanism to stop flow of operating fluid to auxiliary pump.

Oil Diffusion Ejector Pump PFL Series

Oil Diffusion Ejector Pump PFL Series

PFL-type oil diffusion pump is designed and manufactured based on our extensive research and manufacturing experience. It is used in many high-vacuum production facilities, and its practical performance is highly appreciated.

Features

  • Excellent pumping speed
  • Low back-streaming of the operating fluid
  • Minimized power required and fluid capacity to ensure low operating cost
  • Easy maintenance
  • Reliable pump body construction
  • Come with mechanism to stop flow of operating fluid to auxiliary pump.

Oil Diffusion Ejector Pump PBL Series

Oil Diffusion Ejector 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.

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.
  • Come with mechanism to stop flow of operating fluid to auxiliary pump.
