Pumps Case Studies and White Papers

  1. Minimizing Energy Use At Pump Stations With Extreme Variable Flows

    Every spring, the wastewater municipality in Dalarna, Sweden, experienced melting snow and heavy rainfall that caused a dramatic increase in pump station inflow. To handle this seasonal volume, the station had oversized pumps that consumed more energy than needed during drier months. This case study illustrates how the installation of a variable-speed pump controller decreased energy consumption by almost 50 percent while allowing for variations in flow.

  2. Picking The Perfect Pump

    Pumps and pumping systems are like unsung heroes of modern society – quickly and quietly transporting vital water supplies, chemicals and waste to and from locations, which rely upon their consistent, reliable operation.

  3. AMERICAN’s Versatility Shines In Rocky Terrain

    Murfreesboro, Tennessee, is the fastest growing city in Tennessee, and one of the fastest growing cities in the United States with its population more than doubling since 2000.

  4. Michigan Utility’s New Pumps Underscore Advancements In Wastewater Handling

    Ypsilanti’s pumps, originally put into service in 1982, became priority candidates for replacement after operating ten years beyond their expected 20 year service life. The Ypsilanti Community Utilities Authority (YCUA), included the project in the utility’s Master Plan.

  5. WWTP Reaches Clog-Free Operation With Self-Cleaning Impellers

    As with many plants modified for activated sludge treatment, the existing infrastructure at the Adams Field Wastewater Treatment Plant in Little Rock, AR, allowed rags and other debris to clog the impellers of the submersible pumps. One of the plant’s two 15-horsepower pumps was replaced with an 18-horsepower RAS submersible pump with a self-cleaning impeller, virtually eliminating the clogging problem by simply pumping away any debris that reaches the pump intakes.

  6. Pre-Engineered Lift Stations Deliver Fix For Aging Pumps At Private Sewer Utility

    Undersized original construction and gradual equipment deterioration led to recurring pump station failures and overflows for the Valley Rural Utilities Company’s wastewater collection system in Lawrenceville, Indiana.

  7. Lift Station Reduces Clogging, Lowers Operating Expenses With Self-Cleaning Pumps

    Aging pumps at Jackson Energy Authority’s Rolling Acres Lift Station (Jackson, Tenn.) resulted in frequent clogging and outages that required costly maintenance and repair.

  8. Dry-Pit Submersible Pumps Replace Oversized Long-Shaft Pumps

    After anticipated growth of the New Jersey casino industry fell short, Atlantic City Sewerage Company’s Baltic Avenue Pump Station was left with grossly-oversized long-shaft sewage pumps that operated inefficiently and were prone to cavitation.

  9. Wireless Lift Station Monitoring Application Note

    Powerful Pump Monitoring for Optimal Lift Station Performance. Trimble Unity software combined with the Telog wireless, battery-powered, multi-channel recording telemetry system provides a GIS-centric cloud and mobile platform for monitoring lift station pump on/off cycles along with sump levels. Clamp-on current sensors monitor pump run on/off to one second resolution. 

  10. A Guide To Wastewater Pump Materials: Selecting The Right Materials To Extend System Life And Raise Performance

    Wastewater can be both corrosive and abrasive. To ensure reliable and cost-effective pump operation, it is important to select a wastewater pump made from the most suitable material for your wastewater.
