Berkeley S39533 Ac Straight Pump 1 Hp 115/230V

Product Description

The BERKELEY S39533 is a single-phase AC straight pump rated at 1 horsepower and designed for demanding water transfer and circulation applications. It operates on 115/230 volts at 60 Hz, giving installers flexibility in matching the supply voltage at the job site. The cast iron housing delivers the structural durability required in commercial and industrial service environments, while the brass impeller handles flow without accelerated corrosion. With a maximum head pressure of 113 psi and a flow rate of 60 GPM at 20 feet of head, this pump is built for high-volume, high-head scenarios. Licensed plumbers, pump contractors, and industrial maintenance techs are the typical installers.

The S39533 is suited for residential and light commercial water transfer, irrigation, dewatering, and booster applications where a reliable single-phase motor and robust wetted materials are required. The 1-1/4 inch FPT inlet and 1 inch FPT outlet allow direct threaded connection to standard pipe runs. The open drip-proof (ODP) motor design is appropriate for indoor or sheltered outdoor installations where the motor is protected from direct water exposure. The pump handles fluid temperatures up to 225 degrees F, making it compatible with hot water circulation duties as well.

Installation Notes

Installation should be performed by a licensed plumber or qualified pump technician in accordance with local plumbing codes and the applicable sections of the International Plumbing Code (IPC). Shut off all upstream supply valves and de-energize the circuit at the breaker before making any connections. Verify that the supply voltage matches the motor's configured tap before energizing. Do not run the pump dry, as loss of prime can damage internal components.
