  • No pressure tank needed, micro-controller regulated
  • Maintains 40psi pressure when water is running
  • Builds up to 60psi reserve pressure when faucet is closed
  • Runs on 12V DC Power
  • Replaces R4525-743
  • CSA Listed and C.E. Certified


The Flojet Sensor R4426 V-FLO 5.0 gpm variable speed sensor-controlled water system pump is available in 12V or 24V models. A solid-state micro controller regulates flow, according to the Hall-Effect pressure sensor. This revolutionary control design allows the variable speed pump to operate without an accumulator tank or a traditional pressure switch. Ends cycling and water hammer. Self priming and can run dry without damage.

While water is flowing, the 4426 will maintain constant water pressure at its rated sensor pressure (40 psi), up to 5 gallons per minute water flow. When the outgoing water flow (faucet) is closed, the pump will build up to its rated cut-off pressure (60 psi) before shutting itself off. This allows a ‘reserve’ of water pressure to be maintained for the next time a faucet/water outlet is opened.

The R4426 control system allows the pump to operate at maximum efficency under all conditions, saving energy and extending the pump’s operational life. Runs almost silently under normal use. Can handle water temperatures up to 160F. NOTE: This pump is not continuously rated, and should not be run for more than 15 minutes at a time. The R4426-143A is CSA listed and C.E. certified for US and Canadian sales. (This model was previously the R4525-743, the specifications have been updated for the new model.)
