Berkeley S39529 Ac Straight Pump 1/2 Hp 115/230V

Product Description

The BERKELEY S39529 is a single-phase AC straight pump designed for water transfer and circulation in residential and light commercial applications. Rated at 1/2 horsepower and dual-voltage capable at 115/230 volts, this pump delivers reliable performance up to a maximum head pressure of 83 psi. The cast iron housing provides durability in demanding service environments, while the brass impeller resists corrosion in clean water systems. The 1-1/4-inch FPT inlet and 1-inch FPT outlet suit standard pipe connections. Licensed plumbers and pump contractors typically handle installation and commissioning of this unit.

This pump is suited for residential water systems, irrigation, and light industrial fluid transfer where a compact, direct-drive straight pump configuration is required. It operates on 60 Hz single-phase power and handles fluid temperatures up to 225 degrees F, making it appropriate for a range of hydronic and water supply applications. The open drip-proof (ODP) motor design is intended for indoor or protected outdoor installations where the motor is not exposed to direct moisture or weather.
