It handles clean liquids with suspended sand content up to 300 g\/m³ and supports continuous duty for pressurised networks.\u003c\/p\u003e\u003cp\u003eA 4 kW three-phase motor at 415V drives the 15-stage assembly, achieving a peak head of 76 meters and a maximum flow of 400 L\/Min. The motor coupling conforms to NEMA standards, allowing for reliable synchronisation and simplified field maintenance.\u003c\/p\u003e\u003cp\u003eWithin each stage, LEXAN floating impellers move axially against polycarbonate diffusers, helping to prevent stage seizure when sand particles enter the casing. This design supports consistent operation during bulk transfer 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 shield the hydraulic assembly from water column weight and reverse rotation. Rated for liquid temperatures up to 35°C, the unit 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 reducing internal binding risk\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers maintain an efficient hydraulic flow path for reduced energy consumption\u003c\/li\u003e\n\u003cli\u003eFifteen-stage radial hydraulic assembly delivers 76 meters of head for bulk water supply and storage systems\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel jacket provides a corrosion-resistant shell for deep borehole immersion\u003c\/li\u003e\n\u003cli\u003eBuilt-in non-return valve protects the internal hydraulics and motor from backflow and water weight\u003c\/li\u003e\n\u003cli\u003eNEMA-standard coupling enables flexible pairing 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 safe, reliable performance under continuous well immersion\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50983322845431,"sku":"4SDP 16\/15-W","price":1906.47,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-16-15-w-stainless-steel-4-inch-submersible-bore-pump-residential-tank-filling.png?v=1785325873","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-16-15-w-stainless-steel-4-inch-submersible-bore-pump-residential-tank-filling","provider":"Foundation Pumps","version":"1.0","type":"link"}
