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":"Default Title","offer_id":49077979742452,"sku":"NPD4-299-299","price":3489.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0828\/7784\/1652\/files\/1787711176020.png?v=1787713341","url":"https:\/\/shop.phoenixenergysupply.com\/products\/dual-circuit-4-pump-2-26-99-2-26-99-208-230-v-np-3-way-flush-ports-flo-link-connections-1","provider":"Phoenix Energy Supply","version":"1.0","type":"link"}
