Description

–
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, longlife 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.

Applications:
  • 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

    Features:
  • A complete and packaged system: Pump, motor, drive and pressure switch in one box
  • Small and compact design: Fits into small areas, even between floor joists
  • Stainless steel construction: Made for years of operation
  • Simple and easy installation: Step-by-step illustrated instructions
  • Quiet and cool operation: Integrated motor design allows water to flow around it
  • NEMA 4 electronics enclosure
  • Multiple mounting configurations
  • Install units where you need them: horizontal, vertical & even upside down
  • Product power rating: 1.2 hp, 0.9 kW
  • Built in system protections guard the Inline unit from many common failure modes including: surge protection, voltage underload, locked pump, open circuit, short circuit and overheated controller.

    This product has served me well

    Pump came sooner than expected. I have it installed and works great (This is my 3rd one). The main feature i like about these pumps is the quiet operation. Only issue is I wished they lasted longer (around 4-5years). But, alas, nothing last that long anymore...

    Great pump...when it works

    I bought my first one through Supply House in January of 2020. It lasted 13 months before giving up the ghost. I got my warranty replacement in February of 2021. As of 3 days ago, it now sounds like a jet engine taking off. Since I'm 5 months out of warranty, I'm boned. I'll let it run until it explodes or burns my well house down. These are not cheap. I wish they lasted longer.

    Unreliable

    I had high hopes for this pump and, unfortunately it has not lived up to expectations. I bought my first one of these pumps and installed it only to have it start making a lot of noise that sounded like bearing failure after a little over a year. The warranty is 2 years, but you have to return the pump to the authorized seller that you purchased it from. Unfortunately they are not around anymore. So, I purchased another one of the same pumps in order to get my system up and running as soon as possible. Well that pump lasted about 6 months before it just went completely dead. In conclusion, I am moving on to a different manufacturer and pump system. The manufacturer has been absolutely no help whatsoever.

    This is a great pump, quiet, efficient.

    I have 2 of these pumps. One for the domestic water and one for irrigation. Works great, top of the line pump.

    Have purchased this item many times.

    We use this product in many applications, from residential water supply to agricultural chicken buildings and many in between. Easy to install, easy to operate, and we have had no problems in about 3 years from first install.
