Little Giant 25LGIL1100N4 (90411101) Inline Constant Water Pressure System provides consistent water pressure regulation using advanced electronics to drive the pump/motor according to the system's real-time demand. The Little Giant 25LGIL1100N4 includes highly accurate, heavy-duty, long-life pressure sensor for constant monitoring of the water pressure demand.

By adjusting the pump/motor speed, the Inline System automatically reacts to any change in system demand while maintaining a constant output pressure. The Inline System's constant output pressure should not fluctuate more than a PSI or two, even though the overall system's water flow requirement may change dramatically. Small demand on the system results in the motor/pump running at its lowest speed. As greater demands are placed on the system the speed increases accordingly to maintain the desired system pressure.

  • Boosted and consistent water pressure from water storage/cistern systems;
  • Homes - both in private and municipal applications;
  • General pressure boosting;
  • Sprinkler systems;
  • Farming and commercial wash down systems;
