Section 1000 Bulletin 1300 Issued 9/87 Replaces 7/84 jet pump TECHNICAL data pumpinggasesThis TECHNICAL bulletin includes general informationabout Penberthy Jet pumps plus specific details forselecting the proper unit. The Penberthy Jet Pumpscovered in this bulletin are used for pumping basic functions of all models included are eitherexhausting, evacuating or jet pumps operateAll jet pumps operate on theprinciple of a fluid entraining asecond fluid. Although design andconstruction may vary, thisapplies to all jet jet pumps have three commonfeatures: inlet, suction, anddischarge. Here is how thesefunction:Inlet The operating medium(liquid, gas, or steam) underpressure enters the inlet andtravels through the nozzle into thesuction chamber. The nozzleconverts the pressure of theoperating medium into a highvelocity stream, which passesfrom the discharge side of the pumping action beginswhen vapor, gases , or liquid in thesuction chamber are entrained bythe high velocity stream emergingfrom the inlet nozzle, lowering thepressure in the suction resulting action causes theliquid, gas, or vapor in the suctionchamber to flow toward - The entrainedmaterial from the suction systemmixes with the operating mediumand acquires part of its energyin the parallel section.
The LM and ELL Jet Pumps are used for exhausting, evacuating and priming operations where a liquid operating medium is available in a 20 to 200 PSIG pressure range.
