Ejectors, are devices for the conveyance, compression or mixing of gases, vapors, liquids or solids in which a gaseous or liquid medium serves as the motive force. They are "pumps without moving parts".
Ejectors, also known as jet pumps, are versatile, reliable in operation and almost maintenance-free. Manufactured in various materials, they can be used nearly everywhere. They operate by the conversion of pressure energy into velocity in suitable nozzles.
