The Grundfos UP 20-45 N provides fixed-speed, continuous operation with a higher head rating than smaller circulators in the range, maintaining circulation performance at the furthest points of the loop.\u003c\/p\u003e\r\n\u003cp\u003eFixed-speed and continuous by design, it delivers 38.2 L\/Min against 4.5 m of maximum head, powered by a 120 W motor drawing 0.52 A on 1 x 240 V. The available head allows the pump to maintain circulation through longer return lines where pressure losses are higher, supporting larger domestic systems and small commercial kitchens.\u003c\/p\u003e\r\n\u003cp\u003eThe stainless steel body and composite impeller are approved for potable water use, with a liquid temperature range extending down to -25°C and up to 110°C — wider than most domestic circulators — which suits installations exposed to cold plant rooms or unheated risers. Maximum system pressure is rated to 10 bar.\u003c\/p\u003e\r\n\u003cp\u003eInternal thermal protection is built into the motor rather than relying on impedance limiting alone, and the enclosure is rated IPX2D for contact protection in service environments. At 150 mm port-to-port with 1 1\/4 inch connections, it retrofits into the same pipe spacing as smaller models where more capacity is later required.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eHigher head rating provides additional pressure capability for longer domestic and light commercial return lines\u003c\/li\u003e\r\n\u003cli\u003eInternal thermal motor protection safeguards the winding against overload in continuous operation\u003c\/li\u003e\r\n\u003cli\u003eStainless steel housing with potable water approval resists corrosion in hot water service\u003c\/li\u003e\r\n\u003cli\u003eWide liquid temperature tolerance from -25°C to 110°C for installations in cold environments\u003c\/li\u003e\r\n\u003cli\u003eIPX2D enclosure rating provides protection against dripping water and contact in service environments\u003c\/li\u003e\r\n\u003cli\u003eComposite impeller construction offers corrosion resistance in potable hot water applications\u003c\/li\u003e\r\n\u003cli\u003eFixed-speed design eliminates the need for user adjustment during commissioning and operation\u003c\/li\u003e\r\n\u003cli\u003e150 mm port-to-port body dimension supports straightforward retrofit installation\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50978282111223,"sku":"95906472","price":857.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-up-20-45-n-stainless-steel-fixed-speed-circulator-pump-for-tankless-water-heaters.png?v=1785223206","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-up-20-45-n-stainless-steel-fixed-speed-circulator-pump-for-tankless-water-heaters","provider":"Foundation Pumps","version":"1.0","type":"link"}
