Ejector : An ejector is a fluid-driven device used to create vacuum, mix fluids, or transfer energy from a high-pressure motive fluid to a lower-pressure suction fluid. It operates on the principle of momentum transfer, typically using steam, gas, or liquid as the driving force. The ejector has no moving parts, making it simple, reliable, and suitable for harsh environments. The basic operation involves the high-pressure motive fluid being accelerated through a converging-diverging nozzle, conve
