Ejector for pump

Reliable solution for fully automated priming

Sulzer ejector is suitable for all standard process pumps. It offers an easy solution for enabling fast, reliable and fully automated priming for retrofitting existing or new installations. It also includes a full automation package (optional).

Ejector for priming
Main benefits
  • High efficiency - ejector consumes no energy during normal pumping sequence
  • Reliable due to automated priming
  • Easy to install and use
  • Low energy consumption because pressurized air is only required during priming
  • Low installation, maintenance and operating costs
  • Service-free (no rotating parts), robust and simple design
Main applications
  • Clean and slightly contaminated liquids
  • Seawater
  • Liquids containing particles with max. size 3 mm / 0.2 inch
Fully automated ejector package
Full ejector package

For fully automated priming, the Sulzer ejector package includes:

  1. Sulzer ejector unit
  2. Valves with actuators for motive air and ejector suction pipe*
  3. Level-control switch
  4. Control box with logic
  5. Wires (5 m / 16.4 ft.)
  6. Documentation

Sulzer ejector can also be supplied without automation package. In this case delivery includes only the ejector unit and automation diagrams.

*pump discharge valve is not included
