Berkeley S39522 Ac Straight Pump 1-1/2 Hp 115/230V

Product Description

The BERKELEY S39522 is a single-phase AC straight pump designed for water transfer and circulation in commercial and industrial plumbing, irrigation, and HVAC hydronic applications. Rated at 1-1/2 horsepower and dual-voltage capable at 115/230 volts, this pump delivers strong flow performance across a wide range of head conditions — up to 70 GPM at 20 feet of head and up to 35 GPM at 100 feet of head. The cast iron housing provides durability in demanding environments, while the Noryl impeller resists corrosion and chemical degradation. The open drip-proof (ODP) motor operates on 60 Hz single-phase power. Licensed plumbers, pipefitters, and mechanical contractors typically specify and install this unit in fluid-handling systems requiring reliable, high-flow performance.

The S39522 is suited for residential and light commercial water supply, pressure boosting, and recirculation systems where a compact straight-pump configuration is required. The 1-1/4 inch FPT inlet and 1 inch FPT outlet allow straightforward integration into standard threaded piping. The pump handles fluids up to 140 degrees F, making it appropriate for hot water systems as well as cold water applications. Its dual-voltage motor wiring offers flexibility for field configuration to match available service voltage.

Compatibility

Designed as an OEM-style replacement or direct installation pump for single-phase AC water supply, pressure booster, and recirculation systems requiring 1-1/4 inch FPT inlet and 1 inch FPT outlet connections.

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 disconnect power at the breaker before removing or installing the pump. Verify available service voltage before wiring — the motor must be configured for either 115V or 230V operation as appropriate. Do not exceed the rated fluid temperature of 140 degrees F, and ensure adequate pipe support to prevent strain on the pump flanges.
