  • Desubmerge Your Submersible Pump

    A few decades ago, well, definitely not more than four, a contractor was introduced to electric powered submersible pumps. The crew’s first reaction was, “What! You’re going to throw that electric motor in the water? You’ve got to be crazy!” After a few weeks of getting comfortable with the subs, the whole crew was handling them like ...

  • 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 ...

  • Pumps for the Booming FPSO Sector

    In the last few years, several new offshore oil fields have been discovered. The current findings from Petrobras and other companies in the pre-salt province, located in the Brazilian continental shelf, suggest reserves of over 50 billion barrels of oil. Extracting the pre-salt oil is challenging and done increasingly with floating production storage and offloading units (FPSOs). Sulzer offers a ...

  • Suwanee Creek pumping station, Gwinnett County, GA

    That's high head," says Roger Toebben, P.E., about the 350 feet of total dynamic head handled by the Suwanee Creek Pumping Station, which has been up and running since January 2001. "There are a few sewage pumping stations like this, but they're not real common." Very high static head and a long force main (42,500 feet) led to the notably elevated dynamic head, which meant that a ...


  • 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 ...

  • 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 ...

  • A method for reducing purge volumes in deep monitoring wells: a purging experiment.

    Regulatory agencies often require three well casing volumes or more be purged prior to collection of groundwater samples for chemical analysis. Costs are high for testing and disposing of potentially hazardous purge water; therefore, efforts must be made to minimize waste-water volume while obtaining representative groundwater samples. Lockheed sponsored a purge experiment on two deep monitor ...
