Berkeley S39523 Ac Straight Pump 1-1/2 Hp 3 Phase

Product Description

The BERKELEY S39523 is a three-phase AC straight centrifugal pump rated at 1-1/2 horsepower and designed for demanding fluid transfer applications in commercial and industrial settings. It operates on 208 to 230/460 volts at 60 Hz and delivers up to 70 GPM at 20 feet of head, with a maximum head pressure of 118 psi. The cast iron housing provides durability under continuous service conditions, while the Noryl impeller resists corrosion and wear. Licensed plumbers and mechanical contractors are the typical installers of this unit in piping systems where flow rate and head pressure requirements must be matched to the pump curve.

The S39523 is suited for commercial HVAC hydronic circulation, industrial fluid transfer, and agricultural or irrigation systems requiring a robust three-phase pump. It features female pipe thread (FPT) inlet and outlet connections, with a 1-1/4 inch inlet and a 1 inch outlet. The open drip-proof (ODP) motor makes it appropriate for indoor or sheltered installations where exposure to splashing is limited. It handles fluid temperatures up to 140 degrees F, making it compatible with a range of hot water and process fluid applications.

Compatibility

Designed as an OEM-style replacement or direct installation centrifugal pump for three-phase commercial and industrial piping systems requiring a 1-1/4 inch FPT inlet and 1 inch FPT outlet configuration.

Installation Notes

Installation should be performed by a licensed plumber or mechanical contractor in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Disconnect and lock out all electrical power before servicing or installing the pump, and verify that the supply voltage and phase configuration match the motor nameplate before energizing. Ensure the pump is primed before startup to prevent dry-run damage to the impeller and seals. Confirm that pipe support is adequate to avoid placing stress on the pump housing connections.
