Berkeley S39516 Ac Straight Pump 1/2 Hp 115/230V

Product Description

The BERKELEY S39516 is a single-phase AC straight pump designed for water transfer and circulation applications in residential and light commercial systems. Rated at 1/2 horsepower and dual-voltage capable at 115/230 volts, this pump delivers up to 37 GPM at 20 feet of head and maintains a maximum head pressure of 83 psi. The cast iron housing provides durable, long-term service in demanding installations, while the Noryl impeller resists corrosion and chemical degradation. Connections are female pipe thread (FPT) on both inlet and outlet, with a 1-1/4 inch inlet and 1 inch outlet. Plumbers and pump service technicians are the primary installers for this unit.

The S39516 suits applications where a reliable open drip-proof (ODP) motor and chemical-resistant impeller are required. Typical installations include water supply systems, irrigation boosting, and general fluid transfer in residential or light commercial settings. The dual-voltage configuration allows the pump to be wired for either 115 or 230 volt service depending on available power at the installation site. Operating at 60 Hz, it handles fluids up to 140 degrees F, making it appropriate for a range of pumping tasks beyond cold-water-only service.

Key Features

• Dual-voltage motor: field-wired for 115 or 230 volt single-phase service
• Cast iron housing for durability in continuous-duty installations
• Noryl impeller resists corrosion and common water treatment chemicals
• ODP motor design suits dry, ventilated mechanical room environments
• FPT x FPT end connections simplify threaded pipe installation
• Handles fluid temperatures up to 140 degrees F

Compatibility

Designed as an OEM-style replacement or direct-install straight pump for single-phase residential and light commercial water supply and circulation systems requiring a 1/2 hp, 115/230V AC pump with a 1-1/4 inch FPT inlet and 1 inch FPT outlet.

Installation Notes

Installation should be performed by a licensed plumber or qualified pump technician in accordance with applicable local plumbing codes. Shut off power at the circuit breaker and close all supply and discharge isolation valves before servicing or replacing the pump. Verify the supply voltage matches the selected motor wiring configuration before energizing. Ensure the pump is primed before first start to prevent dry-run damage to the seal and impeller.
