It is sized for smaller domestic loops, such as those serving single-family homes with a dedicated hot water return.\u003c\/p\u003e\r\n\u003cp\u003eThe pump is rated for 20.7 L\/Min at 3 m of head, running at a fixed continuous speed on 90 W and 0.34 A from a 1 x 240 V supply. Because output isn't adjustable, sizing during specification is important, but the unit has no speed selector to configure over the course of its service life.\u003c\/p\u003e\r\n\u003cp\u003eA stainless steel pump housing paired with a composite impeller makes the UP 20-30 N suitable for potable water circuits, with the wetted parts resisting corrosion in oxygenated domestic supplies. Liquid temperatures up to 110°C and system pressures to 10 bar are supported, covering both standard tank heaters and higher-temperature tankless units.\u003c\/p\u003e\r\n\u003cp\u003eHoused to IP44 for undercover fitting, the pump has a 150 mm port-to-port length and 1 1\/4 inch threaded connections that align with common domestic pipework. Impedance-protected motor construction incorporates overload protection directly into the winding, eliminating the need for external starters or relays.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cul\u003e\r\n\u003cli\u003eFixed-speed operation with no selector switch simplifies installation and ongoing system configuration\u003c\/li\u003e\r\n\u003cli\u003eStainless steel pump housing with potable water approval provides corrosion resistance in domestic hot water supplies\u003c\/li\u003e\r\n\u003cli\u003eComposite impeller construction offers consistent hydraulic performance in hot water recirculation applications\u003c\/li\u003e\r\n\u003cli\u003eImpedance-protected motor design incorporates overload protection without external protection devices\u003c\/li\u003e\r\n\u003cli\u003eMaximum system pressure rating of 10 bar accommodates both standard domestic and higher-pressure systems\u003c\/li\u003e\r\n\u003cli\u003eWetted materials certified for drinking water contact, meeting relevant potable water regulations\u003c\/li\u003e\r\n\u003cli\u003e150 mm port-to-port body dimension aligns with standard domestic pipework configurations\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50978282078455,"sku":"59643600","price":721.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-up-20-30-n-stainless-steel-fixed-speed-circulator-pump-for-hot-water-return-lines.png?v=1785223205","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-up-20-30-n-stainless-steel-fixed-speed-circulator-pump-for-hot-water-return-lines","provider":"Foundation Pumps","version":"1.0","type":"link"}
