An eductor-jet pump or jet pump is a type of pump where the energy from one fluid (liquid or gas) is transferred to another fluid via the Venturi effect. As the fluid passes through a tapered jet, kinetic energy increases and pressure decreases drawing fluid from the suction into the flow stream.
Used in spas to provide additional thrust into the hydrotherapy jets.
a jet pump is a commonly available residential water supply pump. It has an interesting clever design that can lift water from a well (up to 25 feet) and allow it to function without a check valve on the suction and furthermore does not require priming.
