It handles liquids with sand concentrations up to 300 g\/m³ and supports continuous duty for high-volume residential distribution networks.\u003c\/p\u003e\u003cp\u003eA 4 kW three-phase motor at 415V drives the 13-stage assembly, achieving a maximum head of 65 meters and a peak flow of 400 L\/Min. The motor flange coupling conforms to NEMA standards, ensuring a secure connection point for high-performance 4-inch submersible motors.\u003c\/p\u003e\u003cp\u003eLEXAN floating impellers move axially within each stage against polycarbonate diffusers, helping to prevent motor seizure when abrasive solids are present. The high-flow system maintains stable water delivery during duty 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 protect the hydraulics and motor from back-pressure and reverse rotation. Rated for water up to 35°C, the assembly includes a chrome-nickel steel suction filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSpecial radial floating impellers facilitate sand passage while reducing internal mechanical binding risk\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers reduce turbulence and improve system energy efficiency\u003c\/li\u003e\n\u003cli\u003eThirteen-stage hydraulic configuration delivers 65 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 various submersible borehole motors\u003c\/li\u003e\n\u003cli\u003eChrome-nickel steel suction lantern blocks mineral debris and oversized particulates from the intake\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":50983322812663,"sku":"4SDP 16\/13-W","price":1727.88,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-16-13-w-stainless-steel-4-inch-submersible-bore-pump-industrial-water-supply.png?v=1785325869","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-16-13-w-stainless-steel-4-inch-submersible-bore-pump-industrial-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
