Description
EJECT-ELL & EJECT-LM Series — Bronze Syphon Pumps & Ejectors
The EJECT-ELL & EJECT-LM Series Bronze Syphon Pumps and Ejectors are designed for dependable fluid transfer using water as the motive fluid. These units operate on the ejector principle, where a high-velocity water jet creates a pressure drop that draws fluid through the suction inlet. They are commonly used for circulating, pumping, transferring liquids, water boosting, and handling gas–liquid induction processes across industrial and utility applications.
Constructed from high-quality bronze, these ejectors provide corrosion resistance and long service life in demanding fluid-handling environments. Their compact, threaded NPT connection design ensures simple installation and compatibility with standard piping systems. With motive pressures up to 200 PSIG and maximum inlet suction pressure up to 20 PSIG, the EJECT-ELL and EJECT-LM Series deliver reliable, maintenance-free operation with no moving parts.

Operating Principles
These ejectors operate by accelerating motive water through a precision nozzle, generating a low-pressure zone at the suction inlet. This pressure differential induces additional fluid or gas into the mixing chamber. The combined flow is then discharged smoothly and efficiently, providing a continuous pumping effect. With no internal moving components, they offer exceptionally reliable and consistent performance.
Typical applications include fluid circulation, liquid transfer, tank agitation, aeration, gas induction, water boosting, and general-purpose pumping in industrial and process systems.
