Intelliboost® Multi-Stage VFD Boosting Pump

Pentair's Intelliboost® is the only TRUE variable speed booster with an LCD screen that gives you an easy to use, all-in-one solution for not only boosting, but delivering constant pressure throughout the system.

True constant pressure comes from true variable speed. Even when you use more water the unit holds pressure in a flat line. With a standard booster, more water usage means less pressure.


  • TRUE Variable Speed – The Intelliboost features a variable speed control that adjusts itself as demand changes to hold water pressure (up to 60psi) at the desired level.
  • All-In-One Unit – Includes pump, variable speed drive and tank all in one unit for quick and easy install.
  • Simple Startup – Unit is preset to boost 60PSI, allowing you to plumb it, wire it, power up and go!
  • Built-in Check Valve – Includes a check valve after the discharge to further protect your system.
  • LCD Screen – No blinking lights! The Intelliboost has an easy-to-read LCD screen that tells you the status of your unit in plain text.

Municipal/City Water Systems

Franklin now has an affordable answer for homeowners not satisfied with the water pressure they receive from their city water provider. The Inline 1100 is a simple, efficient product that provides pressure to every fixture all the time.

Private Well Systems

The Inline 1100 provides a constant pressure solution for homes with low yielding wells, where storage tanks or cisterns are used.

Want to add a sprinkler system?

The Inline 1100 is versatile and can be used in place of the standard booster pump often needed for a sprinkler pump system. In addition to its weatherproof NEMA 4 electronics enclosure, the Inline 1100 will adjust the overall system pressure, allowing complete water coverage and shorter system run times.
