Water Jet Eductors

Water jet eductors utilize the kinetic energy of one liquid to cause the flow of another.
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.
Water jet eductors have numerous uses in the plant such as lifting, pumping, mixing and agitation of liquids, granular solids and slurries. Some specific applications include:
draining flooded areas, dewatering sand and coal barges, continuous blending, acidifying, causticizing of oils, pumping food products.
Advantages
- SELF-PRIMING
Eductors require no priming and can be used in either continuous or intermittent operation. - SIMPLE AND RELIABLE
Since the basic eductor has no moving parts to wear or break, only periodic inspection is required. - CORROSION AND EROSION RESISTANT
Because they can be made from most materials or coated with corrosion resistant materials, eductors can be made resistant to the corrosive effects of the liquids handled and the environment. These units are furnished in materials such as: ductile iron, bronze, steel, stainless steel, aluminum, PVC, FRP, Haveg, Teflon, Kynar, and polypropylene to name just a few. - AUTOMATIC CONTROL
Units can be adapted for automatic operation by means of a regulating spindle or a snap valve and float arrangement. - NON-ELECTRICAL
Eductors can be used in hazardous locations where electrically operated alternatives would require expensive explosion-proofing. - EASY TO INSTALL
Either threaded or flanged connections are available. Units are compact, relatively light and can be adapted to a variety of piping configurations. - LOW COST
Water jet eductors are inexpensive in relation to the work they do.
Water jet eductors have numerous uses in the plant such as lifting, pumping, mixing and agitation of liquids, granular solids and slurries. Some specific applications include:
- Emptying tanks and sumps
- Pumping and mixing operations in oil treating systems
- Introducing antiknock agents and coloring additives into gasoline
- Producing emulsions
- Tank mixing
- Intermittent Operation
- Pipeline Heater
