It is configured to process liquids with sand content up to 300 g\/m³ and supports continuous service for high-volume pressurised distribution networks.\u003c\/p\u003e\u003cp\u003eA 2.2 kW motor at 415V drives the 13-stage assembly, achieving a peak head of 75 meters and a flow rate of 220 L\/Min. The mechanical interface conforms to NEMA flange standards, providing a reliable connection point for high-performance submersible borehole motors.\u003c\/p\u003e\u003cp\u003eDurable LEXAN floating impellers move axially within each stage to accommodate sand particles, helping to protect the polycarbonate diffusers from abrasive impact during high-capacity transfer operations.\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 internal hydraulics from back-pressure and reverse rotation. Rated for liquids up to 35°C, the unit 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\u003eSpecial radial floating impellers facilitate sand passage while reducing internal mechanical binding risk\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers enhance fluid velocity and reduce operational energy consumption\u003c\/li\u003e\n\u003cli\u003eThirteen-stage hydraulic design generates 75 meters of head for high-flow domestic and agricultural water supply\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 motor and stages from reverse rotation and column water weight\u003c\/li\u003e\n\u003cli\u003eNEMA-standard coupling enables flexible pairing with various submersible motors\u003c\/li\u003e\n\u003cli\u003eChrome-nickel steel suction lantern provides a barrier against oversized solids and mineral particulates\u003c\/li\u003e\n\u003cli\u003eClass F insulation and IP68 protection support continuous duty in fully submerged wells\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50983322616055,"sku":"4SDP 8\/13-W","price":1099.56,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-8-13-w-stainless-steel-4-inch-submersible-bore-pump-water-supply.png?v=1785325858","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-8-13-w-stainless-steel-4-inch-submersible-bore-pump-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
