  • Vibration reduction in water pump motor with magnetically boosted Tuned Mass Damper - Case Study

    Problem description: A 75kW water pump motor experiences excessive vibration levels (up to 11mm/s RMS) due to the presence of a structural resonance in the mechanical supporting structure (see below). The frequency of this structural resonance lays in the operating range of the variable speed motor, leading to a significant vibrations amplification. The vibration measurements have been ...

  • What is a Syringe Pump?

    A syringe pump is a type of infusion pump originally developed to help administer drugs to patients in a controlled manner. Early attempts to construct infusion pumps were made in the 19th century. However, the first infusion device was introduced in the 1950s to be used in chemotherapy. In the 1970s, the development of ambulatory infusion technology enabled the pumps to be used in research; ...

  • Bredel 65 pumps eliminates AODD pump issues at major lithium battery plant

    Bredel 65 hose pumps from Watson-Marlow Fluid Technology Group are now providing constant efficiency in ball-milling processes at a high-volume battery plant in China. Previously, ball milling was being compromised by a poorly performing AODD (air-operated double diaphragm) pump used for high-viscosity slurry recirculation. Reduced flow/efficiency and leaks were proving disruptive ...

  • Optimal solving of the pump scheduling problem by using a Harmony Search optimization algorithm

    Pumps are installed in water distribution networks (WDNs) to ensure adequate service levels in the case of poor water pressure (e.g. because of low elevation of reservoirs or high head losses within the WDN). In such cases optimal pump scheduling is often required for the opportunity of significant energy saving. Optimizing the pump operation also allows a reduction in damage and maintenance ...

  • Signs You Need a New Water Pump

    Motor vehicles are built upon small parts doing big jobs. Consider your engine. It is likely the most important machine within your car, truck, or SUV, but it is not made up of one or two components, but thousands. Some engines have over 14,000 different parts to keep them operational. If just one of these parts, such as the water pump, fails, then the entire engine could grind to a halt. ...

  • Rerating Pipeline Pumps

    Pipeline operators transport billions of gallons of oil every year, and they are constantly looking at ways of improving efficiency and reducing costs. Depending on changing network demands, this might require managing an increase or decrease in flow rate in the pipeline, a change in pressure, or a pump upgrade to more efficient technology. Throughout the life of a pipeline, the process ...
