It performs reliably in clean liquids containing sand up to 150 g\/m³ and is rated for continuous operational duty for large-scale tank systems.\u003c\/p\u003e\u003cp\u003eDriven by a 1.1 kW three-phase motor at 415V, the 16-stage assembly delivers a peak head of 101 meters and a maximum flow of 70 L\/Min. The motor flange coupling conforms to NEMA standards, ensuring seamless integration with standardised 4-inch submersible bore motors.\u003c\/p\u003e\u003cp\u003eAxial movement of the LEXAN floating impellers within each stage helps to prevent stage seizure when sand particles enter the casing. This design reduces abrasive wear on internal surfaces and supports consistent operation across the performance range.\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 motor from reverse rotation and water column weight. Rated for liquid temperatures up to 35°C, the unit includes a chrome-nickel steel suction lantern with a fine filter.\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 seized motor risk\u003c\/li\u003e\n\u003cli\u003eHigh-performance polycarbonate diffusers maintain a smooth hydraulic flow path for improved energy efficiency\u003c\/li\u003e\n\u003cli\u003eSixteen-stage hydraulic assembly provides 101 meters of head for high-lift rural water distribution\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel external jacket provides resistance to mineral corrosion and structural deformation\u003c\/li\u003e\n\u003cli\u003eNon-return valve protects the hydraulics and motor from back-pressure and water hammer\u003c\/li\u003e\n\u003cli\u003eNEMA-standard motor coupling enables pairing with various brands of submersible borehole motors\u003c\/li\u003e\n\u003cli\u003eChrome-nickel steel suction lantern with fine-mesh filter prevents debris entry into the hydraulics\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":50983321862391,"sku":"4SDP 3\/16-W","price":1011.67,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-3-16-w-stainless-steel-4-inch-submersible-bore-pump-rural-water-supply.png?v=1785325821","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-3-16-w-stainless-steel-4-inch-submersible-bore-pump-rural-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
