Overview
VersaBoost Pro is a complete constant-pressure booster rather than a pump you build a system around. Inside is a Franklin Electric encapsulated 4 in submersible pump-motor assembly driven by a Franklin-engineered variable frequency drive, with an integrated check valve and expansion tank. It holds a steady set pressure from 14 to 80 psi as demand changes, for city water boosting, constant pressure on private wells, pressurizing from a cistern above or below the unit, re-pressurizing after filtration, and hydroponic or irrigation boosting.
-
Protection built in — underload, overload, overpressure, overheating, anti-cycling and freeze protection.
-
Scales wirelessly — up to four units in parallel, no control panel.
-
Quiet — as low as 45 dB, with rubber feet damping vibration.
-
Easy service — removable top, front and rear covers; the top cover and LCD rotate 180° for front or rear plumbing.
-
Connected — set up from the display or the FE Connect app over Bluetooth and WiFi.
What Ships and What It Needs to Run
Included: the complete VersaBoost Pro: pump-motor, variable frequency drive, integrated check valve, expansion tank and a 6 ft power cord.
Pressure relief valve required, ordered separately. Franklin’s VersaBoost manual calls for a pressure relief valve able to pass full pump flow up to 100 psi, installed near the outlet and piped to a drain that can take full system flow.
Inlet and outlet piping, isolation valves and any added pressure tank: sized to your installation and ordered separately.
Genuine Franklin Electric equipment, factory-new in original packaging — sold and supported by Watermain Supply, an independent industrial supplier.
Franklin Electric Warranty — 3 Years
Franklin Electric warrants VersaBoost Pro for 3 years from the date of installation, but in no event more than 3 years from the date of manufacture (VersaBoost owner’s manual, Standard Limited Warranty).
Growth — Up to Four Units in Parallel
Up to four VersaBoost Pro units link wirelessly into one system. Each unit carries a share of the flow, so each runs higher on its own curve and the set holds pressure at more flow; the 80 psi maximum output stays the same. Franklin publishes no combined table, so size a multi-unit set against the system demand.

Fed by a city main — incoming pressure turns into extra flow at the same set point, up to the 100 psi system maximum. Drawing from a tank or cistern — read the suction-lift table at your lift and set point.
Suction-lift table as printed in Franklin spec sheet M5058; Franklin notes the flow rates are approximations subject to application and atmospheric pressure.
