  • The Versatility of Hydraulic Submersible Pumps

    Hydraulic submersible pumps offer flexibility and performance When determining a pump for an application, there are a number of factors to consider. Hydraulic submersible pumps are an option and give the added benefit of run dry capability, especially when electric powered pumps are of concern due to potential electrical hazards or other reasons, or diesel driven centrifugal pumps ...

  • 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 ...

  • Sedimentation and Subsurface Water Storage Systems

    When engineers and review authorities first encounter our Rainstore3 Subsurface Water Storage System, they will frequently ask how the storage chamber is maintained, especially for the removal of sediment. The structural nature of Rainstore3 is different from all other storage devices, employing a series of closely spaced, hollow, loadbearing columns. These columns make it impossible to ...

  • Submersible Pumps - The Airlift Principle

    The Air lift principle has been around for many years. In fact it was first conceived in 1797 by the German engineer Carl Emanuel Löscher and is one of the most simple and basic ways to pump water and other fluids. Not only is the principle simple, there is not much to go wrong. Airlift in its simplest form had its limitations, but recent developments have enabled far more ...

  • Avoiding Pump Problems

    As with any pump system, there are some basic components involved — a driver, the impeller/pump and the transmission. The basic difference is that instead of a flexible coupling or gear train, the transmission is a hydraulic system. The hydraulic system is composed of a hydraulic pump, hydraulic motor, supply tank, filtration method, cooling method and transfer ...

  • Deep Well Measurement

    Pulsar's superior echo processing was proven once again in this difficult very deep Welsh wet well application featuring a 23m 'shot' that needed to follow the level between the heads of two submersible pumps. The reliability and versatility of the advanced echo processing technology in Pulsars non-contact ultrasonic range has been utilised at the SwanseaWasteWater TreatmentWorks, in a 23m deep ...

  • 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 ...

  • Inox in a landfill

    For collection and transport of leachate, landfill sites are using various types of pumps. Grindex electrical corrosion resistant pumps provide the volume needed where pneumatic pumps and other submersibles pumps fall short. One of the landfills in Illinois has 18 Grindex corrosion resistant pumps in operation and they now have plans to replace all remaining submersibles with Grindex INOX pumps. ...

  • EVERLAST Wet well mounted pump station - Hazelwood West High School - Case Study

    When a St. Louis area high school determined it needed to replace an underground pump station after nearly 40 years of faithful service, school officials implemented a best value approach to the project with a local design-build firm. They evaluated three options: (1) replace all of the pumps and valves in the existing buried pit, along with associated electrical and control work; (2) abandon ...

The system included a ground filter, dual submersible pump sets with control panel, float switches, rainwater ...

  • 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 ...

  • Dewatering Crews Keep the Alameda Corridor Dry and Open for Business

    Griffin installed a multitude of deep wells along the alignment of the proposed railway to allow for construction. The discharge from the wells was pumped via large diameter high density polyethylene pipe (HDPE) to a below grade mixing vault, where a neutralizing agent was introduced to the groundwater as the quality of the groundwater was not allowed to discharge to the designated receiving ...
