It processes clean liquids containing suspended sand up to 150 g\/m³ and supports continuous duty for high-altitude distribution.\u003c\/p\u003e\u003cp\u003eA 5.5 kW three-phase motor at 415V drives the 49-stage assembly, achieving a peak head of 257 meters and a maximum flow of 160 L\/Min. The motor flange coupling conforms to NEMA standards, ensuring seamless integration with high-output 4-inch submersible bore motors.\u003c\/p\u003e\u003cp\u003eAxial movement of the LEXAN floating impellers within each stage helps to prevent seizure when sand particles enter the casing, supporting consistent operation from extreme borehole depths.\u003c\/p\u003e\u003cp\u003eAISI 304 stainless steel forms the external jacket, with a delivery casing incorporating a built-in non-return valve to shield the motor and stages from backflow and water column weight. Rated for liquids up to 35°C, the assembly includes a chrome-nickel steel suction lantern and a Class F insulated motor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRadial floating impellers accommodate sand while reducing internal mechanical binding risk\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers reduce internal turbulence and improve hydraulic efficiency\u003c\/li\u003e\n\u003cli\u003eForty-nine-stage hydraulic assembly delivers 257 meters of head for high-lift borehole systems\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel jacket provides a corrosion-resistant shell for ultra-deep well installations\u003c\/li\u003e\n\u003cli\u003eBuilt-in non-return valve protects the internal hydraulics from reverse rotation and column water weight\u003c\/li\u003e\n\u003cli\u003eNEMA-standard coupling simplifies installation and ensures compatibility with various submersible borehole motors\u003c\/li\u003e\n\u003cli\u003eChrome-nickel steel suction lantern and filter provide a barrier against mineral debris\u003c\/li\u003e\n\u003cli\u003eClass F insulation and IP68 protection support reliable performance under full well immersion\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50983322452215,"sku":"4SDP 6\/49-W","price":2302.91,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-6-49-w-stainless-steel-4-inch-submersible-bore-pump-commercial-water-supply.png?v=1785325851","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-6-49-w-stainless-steel-4-inch-submersible-bore-pump-commercial-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
