It accepts a 0-10 VDC control signal, allowing the pump speed to be modulated by a boiler or building automation controller. This assembly is intended for integration into hot water heating systems where precise flow management is required. Installation is typically performed by licensed HVAC technicians or plumbing professionals familiar with hydronic system commissioning.\u003c\/p\u003e\n\u003cp\u003eThis pump assembly is suited for residential and light commercial hydronic applications where variable-speed, electronically controlled pumping is specified. The 1.25-inch flange connection simplifies integration into existing or new piping configurations. Systems requiring analog 0-10 VDC pump control signals will find this assembly compatible with a wide range of modern boiler controls and building management inputs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1.25-inch flange connection for straightforward piping integration\u003c\/li\u003e\n  \u003cli\u003e0-10 VDC input signal supports variable-speed pump operation\u003c\/li\u003e\n  \u003cli\u003eDesigned for hydronic heating system applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with boiler controls and building automation systems using analog output signals\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or system component for LOCHINVAR hydronic boiler installations requiring a 1.25-inch flange pump assembly with 0-10 VDC variable-speed control.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber qualified in hydronic systems. Shut down and depressurize the system and isolate the pump circuit before beginning work. Verify that the control wiring supplying the 0-10 VDC signal is de-energized prior to making electrical connections. Follow applicable local mechanical and plumbing codes throughout the installation process.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlange Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eControl Signal\u003c\/strong\u003e: 0-10 VDC\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: LOCHINVAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: L100304110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LOCHINVAR","offers":[{"title":"Default Title","offer_id":51346137121074,"sku":"L100304110","price":515.51,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552652.jpg?v=1782071769","url":"https:\/\/voomisupply.com\/products\/lochinvar-l100304110-flange-pump-assembly-1-25-in-0-10-vdc","provider":"Voomi Supply","version":"1.0","type":"link"}
