JET PUMP

A liquid jet pump for moving a wide variety of material is described. The liquid jet pump is comprised of a nozzle assembly (307) and a target tube (206), and defines a suction chamber (205). The nozzle assembly is configured to pull in gas, causing a gas bearing effect wherein a layer of gas surrou...

Summary:A liquid jet pump for moving a wide variety of material is described. The liquid jet pump is comprised of a nozzle assembly (307) and a target tube (206), and defines a suction chamber (205). The nozzle assembly is configured to pull in gas, causing a gas bearing effect wherein a layer of gas surrounds the liquid jet flow exiting the nozzle assembly. The liquid jet passes through the suction chamber with minimal deflection, reducing cavitation and improving mixing as educted materials enter the suction chamber and combine with the liquid jet. The combined material is directed into the target tube, which preferably is designed to detach from the other components, is composed of abrasion-resistant material and provides ease of changing parts. The nozzle assembly is preferably positioned within the suction chamber in a way which maximizes vacuum, and the vacuum is maintained in relation to the pressure or vacuum produced by a downstream pump by controlling the gas flow into the nozzle assembly.
