Booster Pump 3/4 hp 120/240V

The Flint & Walling PB0712A071 is a single-phase booster pump rated at 3/4 hp for 115/230V AC operation. Its cast-iron housing and open dripproof motor enclosure suit water-pressure boosting in residential and light-commercial plumbing systems. The 3/4-inch connections match common supply lines for straightforward installation.

Suits pressure-boosting needs.

Homeowners and contractors who need to raise household water pressure from a municipal or well source will find the flow curve useful, delivering 14 gpm at 10 psi down to 6 gpm at 120 psi with a 158 psi shut-off. Buyers who need a pump for large-volume transfer, irrigation flooding or continuous dewatering should look at higher-capacity units designed for those duties.

Fits standard 3/4 in plumbing.

The pump threads directly onto 3/4-inch supply piping and operates on common 120/240V single-phase power, so it integrates without special fittings or three-phase wiring. By maintaining steady pressure across the published flow range, it reduces frequent cycling of the pressure tank and extends switch life in the overall system.

Questions about this item

What pipe size and voltage supply do I need to install the PB0712A071?

The booster pump has a 3/4 in connection and runs on a 115/230V AC single-phase supply, so your plumbing must match 3/4 in and the circuit must provide either 115 V or 230 V.

Will the cast-iron housing and open dripproof motor work with my existing galvanised pipework?

Yes, the pump housing is cast iron and the motor enclosure is open dripproof, both compatible with standard galvanised or copper plumbing as long as the 3/4 in fittings match.

How can I confirm the pump is delivering the rated flow after installation?

Measure the output pressure; at 20 psi you should see about 13.4 gpm, at 40 psi about 12.2 gpm, and at 60 psi about 10.9 gpm, matching the published performance curve.
