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).

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

For fully automated priming, the Sulzer ejector package includes:

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