{"product_id":"npd","title":"NPD Series of Dual Circuit Non-Pressurized Flow Centers","description":"The Dual Circuit NP Flow Center is the appropriate strategy to use a single loop field to serve 2 heat pumps and still have all the benefits of a non-pressurized flow center. Using the Grundfos UPS26-99, UPS26-116 (1 or 2 on each circuit) \u0026amp; the UPS 60-150 (1 on each circuit). Once you calculate the required full load flow rate \u0026amp; corresponding pressure drop you can use the following pump curves to help select whether you need (1) or (2) pumps for each of the two circuits.\u003cbr\u003e\u003cbr\u003e\u003cimg class=\"wp-image-21680 size-medium\" src=\"https:\/\/phoenixenergysupply.com\/wp-content\/uploads\/2024\/12\/26-99-26-116-300x199.png\" alt=\"UP26-99, UPS26-99 \u0026amp; UPS26-116\" width=\"300\" height=\"199\"\u003e UP26-99, UPS26-99 \u0026amp; UPS26-116","brand":"Geo-Flo","offers":[{"title":"(1) 26-99 + (1) 26-99","offer_id":48370799804660,"sku":"GFNPD2-99-99","price":2838.64,"currency_code":"USD","in_stock":true},{"title":"(2) 26-99 + (1) 26-99","offer_id":48370799837428,"sku":"GFNPD3-299-99","price":3225.66,"currency_code":"USD","in_stock":true},{"title":"(2) 26-99 + (2) 26-99","offer_id":48370799870196,"sku":"GFNPD4-299-299","price":3489.1,"currency_code":"USD","in_stock":true},{"title":"(1) 26-116 + (1) 26-116","offer_id":48370799902964,"sku":"GFNPD2-116-116","price":2838.64,"currency_code":"USD","in_stock":true},{"title":"(2) 26-116 + (1) 26-116","offer_id":48370799935732,"sku":"GFNPD3-2116-116","price":3225.66,"currency_code":"USD","in_stock":true},{"title":"(2) 26-116 + (2) 26-116","offer_id":48370799968500,"sku":"GFNPD4-2116-2116","price":3489.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/7784\/1652\/files\/gfnpd2-99-99-npd-series-of-dual-circuit-non-pressurized-flow-centers-1-26-99-1-26-99-eabc06af-ref-3-2048x2048.jpg?v=1781191188","url":"https:\/\/shop.phoenixenergysupply.com\/products\/npd","provider":"Phoenix Energy Supply","version":"1.0","type":"link"}
