It operates on 208 to 230\/460 volts at 60 Hz with an open drip-proof (ODP) motor, making it suitable for indoor and sheltered mechanical room installations. The cast iron housing provides durability in commercial and light industrial environments, while the brass impeller resists corrosion in clean water service. The pump delivers up to 70 GPM at 20 feet of head and a maximum head pressure of 118 psi, handling a broad range of flow requirements across varying system demands.\u003c\/p\u003e\u003cp\u003eThis pump is suited for commercial and light industrial water supply, pressure boosting, and circulation systems where three-phase power is available. With FPT x FPT end connections, a 1-1\/4 inch inlet, and a 1 inch outlet, it integrates into standard threaded piping systems. Licensed plumbers and mechanical contractors typically specify this pump for booster skids, irrigation systems, and HVAC hydronic applications where sustained flow rates and moderate-to-high head pressure are required. The pump handles fluids up to 225 degrees F.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-1\/2 HP ODP motor rated for 208 to 230\/460V three-phase, 60 Hz power\u003c\/li\u003e\n\u003cli\u003eCast iron housing for strength and long service life in commercial installs\u003c\/li\u003e\n\u003cli\u003eBrass impeller for corrosion resistance in clean water applications\u003c\/li\u003e\n\u003cli\u003eMaximum head pressure of 118 psi with flow rates from 35 GPM to 70 GPM depending on system head\u003c\/li\u003e\n\u003cli\u003eFPT x FPT end connections with 1-1\/4 inch inlet and 1 inch outlet for standard threaded piping\u003c\/li\u003e\n\u003cli\u003eRated for fluid temperatures up to 225 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-install centrifugal pump for three-phase commercial water supply and circulation systems requiring a 1-1\/2 HP straight pump configuration with FPT threaded connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or mechanical contractor in accordance with applicable local plumbing codes and the IPC. Shut off all power at the disconnect and isolate the supply line before installation or service. Verify that the available three-phase voltage matches the pump nameplate rating before energizing. Ensure proper support and alignment of suction and discharge piping to avoid mechanical stress on pump casing connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 208 to 230\/460 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower\u003c\/strong\u003e: 1-1\/2 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Type\u003c\/strong\u003e: ODP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency\u003c\/strong\u003e: 60 Hz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInlet Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutlet Size\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: FPT x FPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Head Pressure\u003c\/strong\u003e: 118 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGPM at 20 Feet of Head\u003c\/strong\u003e: 70 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGPM at 40 Feet of Head\u003c\/strong\u003e: 66 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGPM at 60 Feet of Head\u003c\/strong\u003e: 57 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGPM at 80 Feet of Head\u003c\/strong\u003e: 48 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGPM at 100 Feet of Head\u003c\/strong\u003e: 35 GPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Fluid Temperature\u003c\/strong\u003e: 225 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHousing Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImpeller Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 39 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BERKELEY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: S39536\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BERKELEY","offers":[{"title":"Default Title","offer_id":51540175782194,"sku":"S39536","price":1815.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/714a5590c2a77836bd900c93be92cc53_cc5eacdd-131e-4e04-af0f-fd252be77e8a.jpg?v=1785848020","url":"https:\/\/voomisupply.com\/products\/berkeley-s39536-centrifugal-pump-1-5-hp-3-phase-cast-iron","provider":"Voomi Supply","version":"1.0","type":"link"}
