- 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
- Float throttle prevents ejector from clogging and air from flowing back into the pump
Ejector for pump
Reliable solution for fully automated priming
Sulzer ejector is suitable for all horizontally installed 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).
- Clean and slightly contaminated liquids
- Fibrous slurries, slurries
- Liquids containing particles
Fully automated ejector package
For fully automated priming, the Sulzer ejector package includes:
- Sulzer ejector unit
- Float throttle
- Level switch
- Valves with actuators for motive air and ejector suction pipe*
- Control box with logic
- Wires (5 m / 16.4 ft.)
- Documentation
*pump discharge valve is not included
Sulzer ejector can also be supplied without automation package. In this case delivery includes only the ejector unit, float throttle with level switch and automation diagrams.
