Berkeley S39535 Ac Straight Pump 1-1/2 Hp 115/230V

Product Description

The BERKELEY S39535 is a single-phase AC straight centrifugal pump rated at 1-1/2 horsepower and designed for demanding water transfer, irrigation, and general fluid-handling applications. It operates on 115/230 volts at 60 Hz with an open drip-proof (ODP) motor, making it field-adaptable to standard single-phase power supplies. The cast iron housing delivers structural durability in wet service environments, while the brass impeller resists corrosion in clean-water and light-duty process applications. The pump handles a maximum head pressure of 118 psi and flows up to 70 GPM at 20 feet of head. Licensed plumbers, irrigation contractors, and mechanical service technicians are the primary installers of this unit.

The S39535 suits residential and light commercial installations where a reliable end-suction straight pump is required. Typical applications include water supply boosting, agricultural irrigation, dewatering, and HVAC makeup-water systems. The female pipe thread (FPT) inlet and outlet connections simplify integration into existing threaded pipe systems. The 1-1/4 inch FPT inlet and 1 inch FPT outlet support high-volume flow with manageable velocity losses across the pump curve. The unit is rated for fluid temperatures up to 225 degrees F, extending its usability into light hot-water service scenarios.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical contractor in accordance with applicable local codes and IPC guidelines. Shut off all power and isolate the water supply before removing or installing the pump. Ensure the motor voltage is correctly configured for the supply voltage (115V or 230V) before energizing. Support the pump body independently to avoid placing strain on the connected piping.
