  • Reducing pressure: increase efficiency with Sulzer
    Some industrial processes require the throttling of high pressure fluids. Hydraulic power recovery turbines can convert the excess pressure into mechanical shaft energy and increase the overall process efficiency. Here, Ron Adams from Sulzer Pumps looks at how reverse running pumps can be used as turbines as an economical solution to recover energy.

  • Energy optimization for Grundfos booster sets
    C. Kallesøe, J. Aarestrup and K. Rokkjær of Grundfos analyse the control and design of booster sets from an energy perspective. They investigate how the structure and control can be used to minimize energy consumption, and demonstrate that equally sized pumps equipped with speed control and running at the same speed are a safe design choice.

  • Harmonics can ruin your power supply
    Harmonic distortion is a form of pollution in the electricity supply that can make equipment behave erratically. They can be difficult to identify and users often attribute the symptoms to other causes, frequently applying mitigating action that fails to solve the problem. Here, ABB gives a few examples of how harmonics can be effectively dealt with if properly identified.

  • Hydropower from KSB pumps-as-turbines
    Brazil is known for its use of hydropower, but when a small, remote tourism complex in a Brazilian nature reserve needed additional power supply, a conventional hydropower solution was deemed too expensive. A more affordable option came in the form of a KSB centrifugal pump driving an electric motor acting as a generator.

  • Using motors to detect centrifugal degradation
    Centrifugal pumps are widely used in industry and many are driven by induction motors. Failure due to pump bearing degradation would result in an unscheduled shutdown leading to production and revenue losses. Parasuram Harihara from Corning Incorporated and Alexander Parlos from Texas A&M propose a technique to detect bearing deterioration using the motor’s electrical signals.
