- 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 eductor 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.
Eductors are the most efficient way to pump or move many types of liquids and gases. There are literally hundreds of uses for eductors, particularly in the petrochemical, process, and power industries.
Eductors work in just about any place where there is a need for a more efficient way to pump liquids and solids. The new line of JRG/JT Eductors offers advanced design features and superior technical capabilities to create the eductor for virtually any application.
