It supports applications where large quantities of water must be moved efficiently without reliance on grid electricity.\u003c\/p\u003e\n\n\u003cp\u003ePerformance reaches a maximum head of 15 m while delivering flow up to approximately 150 L\/Min at lower head conditions, derived from the performance curve peak. This enables efficient handling of high-volume transfer requirements with stable output across varying demand conditions.\u003c\/p\u003e\n\n\u003cp\u003eA multi-stage centrifugal hydraulic design with closed stainless steel impellers enables efficient high-flow operation while maintaining stable pressure characteristics. This configuration reduces hydraulic losses and ensures consistent discharge across the working range.\u003c\/p\u003e\n\n\u003cp\u003eThe construction incorporates AISI 316 stainless steel for pump, impellers, and motor components, providing corrosion resistance in submerged environments. A 4-inch design requires a minimum borehole diameter of 104 mm, while integrated protections including dry-running, overload, and voltage safeguards ensure dependable operation.\u003c\/p\u003e\n\n\u003cstrong\u003eFEATURES\u003c\/strong\u003e\n\u003cul\u003e\n\u003cli\u003eClosed stainless steel impeller configuration for high flow performance\u003c\/li\u003e\n\u003cli\u003eDC-powered operation compatible with solar energy systems\u003c\/li\u003e\n\u003cli\u003eIntegrated MPPT maximizing solar energy utilization efficiency\u003c\/li\u003e\n\u003cli\u003eBuilt-in dry-running protection preventing pump damage\u003c\/li\u003e\n\u003cli\u003eOverload and voltage protection ensuring safe motor operation\u003c\/li\u003e\n\u003cli\u003e4-inch construction suitable for larger borehole installations\u003c\/li\u003e\n\u003cli\u003eAISI 316 stainless steel hydraulic components for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve preventing reverse flow\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50740896301303,"sku":"99612829","price":4510.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sqf-5a-3-n-stainless-steel-high-flow-solar-submersible-pump-for-bulk-water-transfer-with-closed-impeller.png?v=1778038544","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sqf-5a-3-n-stainless-steel-high-flow-solar-submersible-pump-for-bulk-water-transfer-with-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
