VFD pump Applications

  • Differential level transmitter for VFD pump control & flow measurement

    An Ontario municipality deploys Portable flowmeters to solve flow rate discrepancies between sewage pump station effluent and lagoon influent flowmeters. Faced with suspension of construction permits due to flow rate uncertainty, the Township of North Glengarry called on Greyline Instruments to help troubleshoot two permanently installed flow meters.

  • Pumps and Wells

    Operational efficiencies make good sense for business and for resource preservation. To extend the life of wells, gain more production from them, and to safeguard expensive pumps and motors from running dry, companies are retrofitting well pumps with VFDs (Variable Frequency Drives). But even with VFDs, wells are not being optimized to produce the maximum sustainable amount of water and are still running dry resulting in damaging hard stops on pump motors.

  • Decanter centrifuge for mining & diamond drilling

    GNLW223 Series Mini Centrifuge is specially designed for small capacity, small footprint, and fine solids separation. It is designed to meet the drilling fluids recycling for mining drilling rigs especially for diamond drilling. The diamond drilling contract can choose to buy single centrifuge unit with electric drive fixed speed or VFD drive variable speed or even the Fully Hydraulic Drive. For the FHD drive Centrifuge, it can use the diesel engine to power the hydraulic pump to feed to the centrifuge without...

  • Force Main Systems Sulfide Odor Control with Hydrogen Peroxide

    Force main systems are typically high sulfide odor generators due to septicity conditions related to full pipe flow and a greater anaerobic slime layer (biofilm) thickness. Primary factors that influence sulfide loading generation in a force main include sewage temperature, BOD, retention time, pipe size and flow. Gaseous hydrogen sulfide (H2S) release at the force main discharge is usually the main concern related to odor and corrosion control needs; however, corrosion problems within the pipe can be of a...
