Berkeley S39532 Ac Straight Pump 3/4 Hp 3 Phase

Product Description

The BERKELEY S39532 is a three-phase AC straight centrifugal pump rated at 3/4 horsepower and designed for continuous fluid transfer in commercial and industrial water systems. Built with a cast iron housing and brass impeller, this pump handles demanding circulation and pressure applications where durability is a priority. It operates on 208 to 230/460 volts at 60 Hz through an open drip-proof (ODP) motor. With a maximum head pressure of 100 psi and a flow rate of 46 GPM at 20 feet of head, it delivers reliable performance across a range of system demands. Licensed plumbers, pipefitters, and mechanical contractors are the typical installers.

The S39532 is suited for residential and light commercial water circulation, booster, and transfer applications where a three-phase power supply is available. The 1-1/4 inch FPT inlet and 1 inch FPT outlet connect directly to standard threaded pipe configurations. Its rated flow performance across multiple head conditions — 40 GPM at 40 feet, 31 GPM at 60 feet, and 21 GPM at 80 feet — makes it a practical fit for multi-story or extended-run piping systems. Maximum fluid temperature is rated at 225 degrees F, supporting hot water and hydronic system use.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and de-energize all electrical circuits before beginning work. Verify that the available three-phase power supply voltage matches the pump motor nameplate before wiring. Do not run the pump dry, as this can damage the seal and impeller.
