Operating on 115 volts AC single-phase power, it delivers a flow rate of 6.16 GPM to maintain consistent fluid circulation through closed-loop systems. Plumbers and hydronic heating technicians install this pump as part of boiler loops, radiant floor systems, and terminal unit circuits. Its compact wet-rotor design integrates the motor and pump into a single sealed unit, eliminating the need for external shaft seals or lubrication.\u003c\/p\u003e\n\u003cp\u003eThe 595916 is suited for hydronic heating loops, domestic hot water recirculation systems, and fan coil unit circuits in residential and light commercial buildings. It performs reliably in closed-loop systems where continuous, low-pressure circulation is required. This pump is a direct fit for retrofit and new-construction hydronic applications where a 115-volt single-phase supply is available and flow demands fall within the UP Series operating range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6.16 GPM flow rate for steady hydronic circulation\u003c\/li\u003e\n  \u003cli\u003e115 volt AC single-phase operation suits standard residential electrical supply\u003c\/li\u003e\n  \u003cli\u003eWet-rotor design requires no external lubrication or shaft seal maintenance\u003c\/li\u003e\n  \u003cli\u003eUP Series platform with broad replacement and retrofit applicability\u003c\/li\u003e\n  \u003cli\u003eCompact footprint allows installation in tight mechanical spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct upgrade for residential and light commercial hydronic systems requiring a 115-volt single-phase circulator pump in the UP Series flow range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber or qualified hydronic heating technician in accordance with applicable local plumbing codes and the International Plumbing Code. Shut off the system, depressurize the piping loop, and drain the affected section before removing the existing pump. Verify voltage and phase compatibility at the supply circuit before energizing the new pump. Do not run the pump dry, as the wet-rotor bearing depends on system fluid for cooling and lubrication.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlow Rate\u003c\/strong\u003e: 6.16 GPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 115 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePhase\u003c\/strong\u003e: 1 Phase\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: UP Series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GRUNDFOS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 595916\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GRUNDFOS","offers":[{"title":"Default Title","offer_id":51525155946802,"sku":"UP1510SU7PTLC-OLD","price":429.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b4ea673d784c6ae8d26394f7e55e3494.jpg?v=1785465726","url":"https:\/\/voomisupply.com\/products\/grundfos-595916-up-series-circulator-pump-115v","provider":"Voomi Supply","version":"1.0","type":"link"}
