Berkeley S39531 Ac Straight Pump 3/4 Hp 115/230V

Product Description

The BERKELEY S39531 is an AC straight centrifugal pump rated at 3/4 horsepower for single-phase, 115/230-volt operation. Built with a cast iron housing and brass impeller, this pump is designed for durability in demanding fluid-transfer applications. It delivers up to 46 GPM at 20 feet of head and maintains 21 GPM at 80 feet of head, with a maximum head pressure of 100 psi. The open drip-proof (ODP) motor runs at 60 Hz and handles fluid temperatures up to 225 degrees F. Licensed plumbers and mechanical contractors are the typical installing trade for this class of pump.

The S39531 is suited for residential and light commercial water supply, irrigation, pressure boosting, and general fluid-transfer systems. The female pipe thread (FPT) inlet and outlet connections simplify integration into standard threaded piping systems. Its 1-1/4-inch FPT inlet and 1-inch FPT outlet sizing make it a practical fit for applications where moderate to high flow rates are required across varying head conditions.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with local plumbing codes and the IPC. Shut off all water supply and disconnect electrical power at the breaker before beginning work. Verify that the supply voltage matches the pump's wiring configuration before energizing. Do not run the pump dry, as this can damage the impeller and seal.
