EVD-24

The EVD-series are the pumps you can trust on.

This Double stage Oil lubricated Rotary Vane pump is built to reach the low vacuum range and is the excellent choice for researchers and industrial people. With its gas ballast valve it is able to pump condensable vapours. Due to its good ultimate vacuum the pump is often used in applications like:

  • Backing pump for high vacuum pumps
  • Leak detectors
  • Electron microscopes
  • Freeze drying
  • Filtration
  • Analytical instruments
  • Coating equipment
  • Load locks
  • Plasma applications
