  • Which Pump Is Right for Me? Pushing Through a Host of Factors to Select the Right Pump
    , let's take a practical look at some common pump application questions: Q: I need a pump to handle water laden with trash, sludge, or other debris?. A: The 6" jet pump and the 6" wellpoint pump will clog from debris and trash, which will result in accelerated wear or reduced performance. The 6" trash

  • Selecting the Right Pumping System for Your Device
    movement within the system stops; the vacuum pump is not needed and frequently turns off. How long the pumping system remains inactive, the demands on the pump when the analyzer performs its next function, and many other factors can be critical to selecting the right pump for the job. For instance
