This submersible pump is suitable for renewable energy applications where consistent supply and efficient operation are essential without dependence on grid electricity.\u003c\/p\u003e\n\u003cp\u003ePerformance reaches a maximum head of 100 m while delivering flow up to approximately 133 L\/Min at lower head conditions, derived from the performance curve peak. This allows efficient medium-head operation while maintaining stable discharge across varying demand requirements.\u003c\/p\u003e\n\u003cp\u003eA multi-stage centrifugal hydraulic design supports medium-to-high flow operation with balanced pressure characteristics across borehole applications. The polyamide impeller configuration reduces rotational mass while supporting efficient hydraulic performance and smooth water delivery throughout the operating range.\u003c\/p\u003e\n\u003cp\u003eThe construction incorporates AISI 316 stainless steel for the pump and motor components, providing corrosion resistance in submerged environments. A compact 3-inch design allows installation in boreholes with a minimum diameter of 76 mm, while integrated protections including dry-running, overload, and voltage safeguards ensure dependable long-term operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePolyamide impeller configuration supporting efficient hydraulic operation\u003c\/li\u003e\n\u003cli\u003eDC-powered operation compatible with solar energy systems\u003c\/li\u003e\n\u003cli\u003eIntegrated MPPT optimizing energy utilization from solar input\u003c\/li\u003e\n\u003cli\u003eBuilt-in dry-running protection preventing operational damage\u003c\/li\u003e\n\u003cli\u003eOverload and voltage protection ensuring safe motor operation\u003c\/li\u003e\n\u003cli\u003eCompact 3-inch construction suitable for narrow borehole installations\u003c\/li\u003e\n\u003cli\u003eAISI 316 stainless steel pump and motor construction for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve preventing reverse flow in vertical installations\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50742594928887,"sku":"92533526","price":5630.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sqf-5-70-n-stainless-steel-solar-submersible-pump-for-pressure-water-supply-with-polyamide-impeller.png?v=1778038901","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sqf-5-70-n-stainless-steel-solar-submersible-pump-for-pressure-water-supply-with-polyamide-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
