  • Submersible Pumps vs. Self-Priming Centrifugal Pumps
    . Vacuum-assisted, non-clog centrifugal. pumps are the most commonly used pumps. for bypasses, because they are capable of. handling large amounts of liquids and solids. and have an air-handling capability. Diesel. powered units flexed coupled to the pump. can be disconnected and replaced with a. horizontal
  • When to Use PD Pumps (Copyright Viking Pump, Inc.)
    When to use a centrifugal or a Positive Displacement pump ("PD Pump") is not always a clear choice. To make a good choice between these pump types it is important to understand that these two types of pumps behave very differently. Flow rate versus pressure By looking at the performance chart

    and low flow. rates. The principle types of nonpositive displacement vacuum pumps are the centrifugal,. axial-flow, and regenerative designs. Single-stage regenerative blowers can provide vacu-. ums up to 7 in. Hg with flows to several hundred cfm. Vacuum capabilities of the other. designs are lower

    and head), depending on the structural characteristics of the pump itself and as a function of the specific system needs. The operation is simple: these pumps utilize the centrifugal effect to move the liquid and increase its pressure. A bladed wheel (impeller), the true heart of the pump, rotates within

    , driven by a suitably large motor. On start-up, the. centrifugal action of the rotor rapidly establishes a circular liquid ring around the shell. of the stator, with more gas space on the low side than on the high side. Vents in the. lower side plates allow gas to be drawn in by the circulating
  • Which Pump Is Right for Me? Pushing Through a Host of Factors to Select the Right Pump
    in performance to all 6-inch pumps. Even if the customer was a little more specific and stated 1,000 gallons per minute at 150 foot head, this is still not enough information to completely determine which pump is proper for the application. For instance, if a typical end suction centrifugal pump is rented from
  • Tests Show That Solid-Body Plastic Pumps Are The Best Choice For Oscillating Applications (.pdf)
    The demands that oscillating-displacement pumps place on their materials of construction are extremely high due to the constant alternating stress to which they are subjected. In contrast to rotating machines such as centrifugal pumps, for example, where the load builds up gradually when
