  • Sioux Falls, Verder Pumps - Case Study

    The Sioux Falls Water Purification Plant in South Dakota USA, had always relied on gravity to feed slaked lime slurry to their softening basins. In 2009, the staff decided to give gravity a helping hand by trialing a pump to move the slurry more effectively. Lime slurry is a dense product to transfer with a high solid content of up to 35%. Due to the slurry’s abrasive nature which causes ...

  • More to Scrubber Pumps than Meets the Eye

    One component, in particular, needs to be carefully selected to ensure safe and efficient sulphur removal. The time is now Shipowners are having to move fast to change fuel type to distillate fuel or LNG, or to install the exhaust gas cleaning systems (EGC systems) known as scrubbers. They’re reacting to new sulphur emission legislation set to come into force in designated ...

  • 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. ...

  • Combining pressure management and energy recovery benefits in a water distribution system installing PATs

    Gravity can play a beneficial role in certain water distribution networks (WDNs), although sometimes high nodal pressures occur. Excessive pressure may lead to several negative effects regarding the network's operation and life. Thus water utilities are obliged to implement pressure management (PM) policies. Instead of just ‘destroying’ energy using conventional measures, there are other PM ...

  • Hydro power myths Explains why various schemes such as a pool pumps or rain gutters or pumping water to a tank will not work

    Making electricity from falling water can seem like magic, and that’s led to lots of misconceptions. Here, we’ll separate fact from fiction when it comes to what microhydro systems can and cannot do. Residential-scale microhydro-electric systems have the reputation of being the holy grail of home renewableenergy (RE) systems. While they lack some of the hype, magic, and bling of ...

  • 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 ...

  • The potential for health risks from intrusion of contaminants into the distribution system from pressure transients

    The potential for public health risks associated with intrusion of contaminants into water supply distribution systems resulting from transient low or negative pressures is assessed. It is shown that transient pressure events occur in distribution systems; that during these negative pressure events pipeline leaks provide a potential portal for entry of groundwater into treated drinking water; and ...

  • 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 ...

  • Replacement Fill Control Valves with Electronic Flow and Metering Improve Pressure, Stop Leakage and Prevent Valve Failures

    The City of Modesto, California is situated 90 miles east of San Francisco and has approximately 200,000 residents relying on 200,000 of gallons of water a day. The City needed to upgrade three water storage tanks that hold approximately 750,000 gallons each. After years of using motor operated valves to fill water storage tanks, the city recognized that there were just too many problems. ...

  • Four Differentiating Facts – Solenoid Vs Hydraulic Diaphragm Metering Pumps

    Cost of Ownership: While it is true that solenoid pumps are often less than half the purchase price of hydraulic diaphragm metering pumps, the total cost of ownership tells a completely different story. Hydraulic diaphragm metering pumps last over 10-15 years in the field with almost no maintenance. Solenoid pumps usually need service and replacement diaphragms every 6-9 months depending upon ...


  • 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 ...
