Eductor - Jet Pump Selection Guide
Eductors (also known as jet pumps ejectors, and Venturi pumps) are the most efficient way to pump or move many types of liquids and gases in the petrochemical, process, and power industries. Each ultra-smooth unit complies with ASME/ANSI B16.5 standards. The Tank Liquid Agitator (TLA), with no moving parts, can be used in a wide variety of open vessels or closed tanks. "In-tank" mounting eliminates the need for costly mounting structures above tanks, while investment costs are minimized by utilizing existing transfer pumps.
Water jet eductors utilize the kinetic energy of one liquid to cause the flow of another. Eductors consist of a converging nozzle, a body and a diffuser and resemble syphons in appearance. In operation, the pressure energy of the motive liquid is converted to velocity energy by the converging nozzle. The high velocity liquid flow then entrains the suction liquid. Complete mixing of the motive and suction is performed in the body and diffuser section. The mixture of liquids is then converted back to an intermediate pressure after passing through the diffuser.
Tank Eductors are designed for "in-tank"applications. The TLA operates on the principle of flow dynamics pressurized fluid is accelerated through the nozzle to become a high velocity stream that entrains tank contents and intimately mixes with them. This combined stream exits the TLA at a high velocity creating a flow field capable of causing additional agitation and mixing the tank contents.
