penberthy pvc jet pump
Providing a practical alternative to more complicated and expensive methods, penberthy pvc jet pumps offer simple, more cost-effective ways to pump, mix or heat a wide range of liquids and gases used in the process industry. Jet pumps can operate with a wide variety of motive liquids and gases. If you recognize any of the following, you can probably use a jet pump.
Penberthy pvc jet pumps pumps have a myriad of uses. Jet pumps not only pump liquids, they can also heat, mix and blend either in-line or in-tank. Jet pumps can evacuate gases, create a vacuum, boost suction pressures, mix granular solids with liquids and move granular solids with compressed air. In fact, you will be surprised at what a jet pump can do to solve your problem.
The purpose of this section and its associated pages is to identify the many uses for jet pumps, to identify pumps for specific processing operations and perhaps recognize new ways to use jet pumps to reduce costs and optimize your plant’s efficiency. We invite you to explore the possibilities of jet pump use in your operation. You might be surprised at the many ways jet pumps can help improve your company’s profitability!
While jet pumps and eductors may differ in appearance, basic operation is the same. Penberthy pvc jet pumps, also known as eductors, operate on the principles of fluid dynamics. An operating fluid media, which is referred to as the MOTIVE, placed under pressure enters the inlet and is forced through the nozzle where it is converted into a high-velocity stream. This high-velocity stream decreases the pressure in the suction chamber, creating a partial vacuum that draws the suction material into the chamber where it is entrained by the motive media. Once the SUCTION stream is drawn in, shear between motive media and the transported material causes both media to be intermixed and pumped out the DISCHARGE outlet, dispelled at a pressure greater than that of the SUCTION stream but lower than that of the MOTIVE. This basic principle of fluid dynamics is what makes jet pumps work.
There are three connections common to all jet pumps (venturi eductors).
MOTIVE Connection: This connection is where the power for the eductor is generated, by increasing the velocity of the motive fluid. The eductor nozzle in this section takes advantage of the physical properties of the motive fluid. Eductors with liquid motives use a converging nozzle as liquids are not generally compressible. Eductors with gas motives utilize converging-diverging nozzles to achieve maximum benefit from the compressibility of the gas. All nozzles for eductors have smooth flow paths. Flow paths with sudden steps or roughness on these high velocity surfaces cause jet pumps to operate less efficiently.
SUCTION Connection: This connection of the eductor is where the pumping action of the eductor takes place. The motive fluid passes through the suction chamber, entraining the suction fluid as it passes. The friction between the fluids causes the chamber to be evacuated. This allows pressure in the suction vessel to push additional fluid into the suction connection of the jet pump. The high velocity of the motive stream in this section of the eductor directs the combined fluids toward the outlet section of the eductor.
Discharge Connection: As the motive fluid entrains the suction fluid, part of the kinetic energy of the motive fluid is imparted to the suction fluid. This allows the resulting mixture to discharge at an intermediate pressure. The percentage of the motive pressure that can be recovered is dependent upon the ratio of motive flow to suction flow and the amount of suction pressure pulled on the suction port. The mixture then passes through the diverging taper that converts the kinetic energy back to pressure. The combined fluid then leaves the outlet.
