Jet pumps utilize the kinetic energy of one liquid to cause the flow of another. Eductors operate on the basic principles of flow dynamics. This involves taking a high pressure motive stream and accelerating it through a tapered nozzle to increase the velocity of the fluid (gas or liquid) that is put through the nozzle. This fluid is then carried on through a secondary chamber where the friction between the molecules of it and a secondary fluid (generally referred to as the suction fluid) causes this fluid to be pumped. These fluids are intimately mixed together and discharged from the jet pump. For complete details visit www.jetpumps.us
Pumping Liquids. For such a usage, a liquid motive is used to pump another liquid. This is extremely beneficial in areas where an electric pump might present an explosion hazard, or where electric lines might not be available such as when draining a sump. Other typical applications include pulling an acid or base into a water stream in order to dilute that acid or base, and for boosting the NPSH (Net Positive Suction Head) of another pump.
Heating Liquids. Using steam as the motive force to pump a liquid also works to heat the liquid. For example, when drawing water from a pond, the need exists to warm that water as it’s being supplied to a process. The jet pump performs two functions in one. Other applications include heating process fluids in line, cooking slurries in line, and heating reactor jackets.
Pumping Gases. In this case, liquid is again used as the motive force. One typical application is the aeration of a liquid in order to reduce BOD (Basic Oxygen Demand) of the fluid. Others include exhausting vapors or gases from a room, evacuating a vessel, scrubbing fumes from a gas, or creating vacuums. In addition, should there be a need to inject air, ozone, chlorine or other gases into a process liquid, eductors will perform that function efficiently and effectively.
