Built for 4-wire, 3-phase electrical configuration, this pump moves fluid through closed-loop or open-loop solar collector arrays and related piping runs. With a 2-gallon capacity and a robust 157.94-pound construction, it is sized for commercial or large residential solar thermal installations. Licensed mechanical and solar installation contractors are the primary tradespeople who specify and install this unit.\u003c\/p\u003e\u003cp\u003eThis pump is suited for solar thermal energy systems where reliable, continuous fluid circulation is required between collectors and storage or distribution equipment. The 3-phase motor configuration makes it appropriate for commercial buildings, large multi-family residential projects, and industrial solar process heat applications where 3-phase power is available at the mechanical room. Its 4-wire wiring scheme supports standard 3-phase motor starter and drive panel connections common in these installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5 HP motor output for reliable circulation in solar thermal and hydronic loops\u003c\/li\u003e\n\u003cli\u003e4-wire, 3-phase electrical configuration compatible with standard commercial motor controls\u003c\/li\u003e\n\u003cli\u003e2-gallon capacity suitable for larger solar collector array piping volumes\u003c\/li\u003e\n\u003cli\u003eSold as a single unit, ready for installation\u003c\/li\u003e\n\u003cli\u003eUPC-verified unit for procurement and inventory tracking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pump for solar thermal and hydronic circulation systems requiring a 0.5 HP, 3-phase electric pump with a 4-wire connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed mechanical or solar contractor familiar with 3-phase motor wiring and solar thermal system requirements. Shut off all electrical power at the disconnect and isolate system fluid pressure before removing or installing the pump. Follow applicable local mechanical codes and NEC requirements for 3-phase motor branch circuit sizing, overcurrent protection, and grounding. Do not energize the pump dry; ensure the system is filled and purged of air before startup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Output\u003c\/strong\u003e: 0.5 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase Configuration\u003c\/strong\u003e: 3-Phase\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring\u003c\/strong\u003e: 4-Wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity\u003c\/strong\u003e: 2 Gallon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 157.94 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 662459946522\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WILLIAMS COMFORT PRODUCTS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5ES05H2GR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WILLIAMS COMFORT PRODUCTS","offers":[{"title":"Default Title","offer_id":51344438100274,"sku":"5ES05H2GR","price":8351.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310542129.jpg?v=1782035949","url":"https:\/\/voomisupply.com\/products\/williams-comfort-products-5es05h2gr-solar-pump-0-5-hp","provider":"Voomi Supply","version":"1.0","type":"link"}
