Jet pumps / Ejectors working principle
Summary
TLDRJet pumps, also known as ejectors, operate by using a gas flow to create a dynamic pressure drop in a motive nozzle, which generates a negative pressure. This pressure difference accelerates the suction medium and pulls it along through impulse transmission in the mixing nozzle. These pumps are robust and low-maintenance due to their simple, moving-part-free design. They can handle gaseous and liquid media and, depending on the design, even solids. Gear produces jet pumps in various materials such as steel, plastic, graphite, and other special materials for specific applications.
