It handles liquids with sand concentrations up to 300 g\/m³ and supports continuous duty for high-demand pressurised networks.\u003c\/p\u003e\u003cp\u003eA 1.5 kW three-phase motor at 415V drives the 8-stage assembly, achieving a peak head of 47 meters and a flow rate of 220 L\/Min. The motor flange coupling conforms to NEMA standards, ensuring seamless integration with high-output 4-inch submersible borehole motors.\u003c\/p\u003e\u003cp\u003eDurable LEXAN floating impellers move axially against diffusers, helping to prevent stage seizure when sand particles pass through the casing. This design supports consistent operation during high-flow cycles.\u003c\/p\u003e\u003cp\u003eAISI 304 stainless steel forms the external jacket, with a delivery casing incorporating a built-in non-return valve to prevent water column drainage and motor reverse rotation during shutdown. Rated for water up to 35°C, the assembly includes a chrome-nickel steel suction filter and a Class F insulated motor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLEXAN radial floating impellers are designed to handle sand while preventing internal wear and binding\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers reduce turbulence and improve system energy efficiency\u003c\/li\u003e\n\u003cli\u003eEight-stage hydraulic assembly delivers 47 meters of head for high-flow industrial and municipal supply\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel external jacket provides a durable shell resistant to corrosive subterranean conditions\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve protects the system from backflow and reduces water hammer impact\u003c\/li\u003e\n\u003cli\u003eNEMA-standard coupling simplifies installation and ensures compatibility with standardised submersible 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":50983322583287,"sku":"4SDP 8\/8-W","price":890.12,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-8-8-w-stainless-steel-4-inch-submersible-bore-pump-industrial-water-supply.png?v=1785325857","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-8-8-w-stainless-steel-4-inch-submersible-bore-pump-industrial-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
