  • Submersible Pumps vs. Self-Priming Centrifugal Pumps

    When selecting a centrifugal pump for bypass work, the first consideration should be NPSHR by the pump. Neglecting the NPSHR of the pump is the single most common mistake when choosing a self-priming or priming assisted pump. A function of the pump design requires part of the 33.9 ft (14.7 in.) available as further defined in this article. A centrifugal, and in a way submersibles, require part ...

  • Pump Performance Checklist

    Keeping your pump in shape will help reduce costs and boost profits! Cut fuel consumption, reduce replacement parts costs and minimize pumping time on every job! A PUMP THAT LETS YOU DOWN when you need it most causes obvious losses of time and money. Not so obvious, but every bit as costly, are losses you can incur with pumps that operate at less-than-peak efficiency. A pump ...

  • Large Diameter Impellers Make Trash Pumps More Versatile

    The introduction of these impellers allow for a higher range of discharge pressure. Pumps are available in many types—diaphragm, positive displacement and progressive cavity—but the most common is a centrifugal pump. Centrifugal pumps have an impeller that spins, transferring energy to the fluid by centrifugal force and directing the water to the discharge point within the ...

  • Pumping Up Safety, Efficiency and A Smarter Design

    The Opportunity The Progress Energy’s Lee Plant, located in Goldsboro, N.C., originally enlisted nine vertical sump pumps within the plant as yard drain pumps – pumps that have motors that are located above the pump and a line shaft that extends down into the length of the sump – whereas the pump is actually at the bottom of the sump. The pumps were enlisted to remove ...

  • Winter is coming: precautions to protect your pumps

    Now that we are running up to December, the weather in the Northern hemisphere is slowly getting colder and colder. Although Western Europe has been fortunate with a reasonably mild fall, we are expected to get a harsh winter this year, meaning that it is good to prepare for the cold season. Being pump people, this means that we need to take precautions to protect our ...

  • Bypass Pumping System - How to choose the right pumping system to securely meet your objectives in a cost effective manner

    Many bypasses are similar in appearance and name, but it’s their subtle differences that require close attention to fully understand component performance parameters. To determine the right pump, we first need to understand many different aspects of the physical conditions of the application – Flow, Lift/Pump Strength, and Distance. FLOW – is the quantity of liquid being ...
