  • Controlling the Flow Capacity of a Metering Pump

    Since a metering pump is usually a positive displacement pump there are two possible ways of controlling the flow capacity. The first one is by adjusting the volume of liquid displaced per stroke of the pump and the second is by adjusting the speed of the strokes. I. Stroke Length – control the displacement volume per stroke II. Speed of Strokes per minute

      Stroke Length ...

  • Sizing and Selecting the Proper Metering Pump: Part 1 of 2

    A typical agriculture or process application can consume large amounts of chemicals during daily operations. While the volumes may be large, though, they must also be very precise, with exact amounts delivered according to strict injection schedules. The pressures—from very high to very low—that the chemicals are injected at must also be governed precisely. This demand for ...

  • Deal With The Pressure - Protect piping system components with Pulsation Dampeners

    Metering pumps with operating pressures of up to 150 psig (pounds per square inch gauge) can create unwanted pressure pulsations within a piping system – a real problem in applications such as filling, mixing and spraying that require a combination of a metering pump’s accuracy and a continuous flow. But the issue can often be addressed with Pulsation Dampeners.The Pulsation Dampeners, usually ...
