  • AODD Pump Efficiency AirVantage™
    Warren Rupp, Inc. has developed a new, patent pending technology that optimizes the pump efficiency and utilizes adaptive optimization as pump application parameters change.
  • Energy savings - VFDs and more
    In these energy-conscious times, pumping applications offer the potential for significant energy savings. Variable frequency drives are commonly applied for this purpose but are not the only solution available. Complementary solutions such as soft starters and energy management systems are also explored here by Jack Creamer and Grant Van Hemert of Schneider Electric.
  • Containment shells for efficiency
    Pumps use a lot of energy, an increasingly important concern today. Here, Dipl. Ing. (FH) Jürgen Konrad looks at the latest designs and materials for containment shells fitted to magnetically-coupled pumps, which can save significant energy for quickly amortised initial outlay. Operators can profit too.
  • The potential of gas shale
    Robert McIlvaine and Ann James of McIlvaine Company show how extracting gas from shale deposits has become ever more economical, and discuss how pumps can play a role in this increasingly important form of energy, looking at a selection of important wells across the U.S.
  • What to do with an old AC drive
