- 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
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).
- Clean and slightly contaminated liquids
- 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.)
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

AHLSTAR™ with Sulzer Ejector improves sump pumping in a cardboard millA cardboard mill customer suffered from regular pump breakdowns in the fiber line effluent sump. Sulzer replaced the two existing submersible pumps by one non-clogging AHLSTAR NPP42-150 pump equipped with a Sulzer Ejector. Read the whole case study.
Reliable and cost-effective sump pumping with Sulzer’s ejectorOne of our key customers in the pulp and paper industry was designing a new wastewater pit for their mill. The wastewater contains particles, impurities and a maximum of 1% fibers. The customer needed to pump the wastewater from a pit 2.3 meters deep and wanted to have an energy-efficient, reliable and easily maintained solution for sump pumping. The alternatives were to use a cantilever pump, a submersible pump, a self-priming process pump or a process pump with an ejector
