It processes clean liquids containing suspended sand up to 300 g\/m³ and supports continuous cycles for high-demand residential distribution and pressurised systems.\u003c\/p\u003e\u003cp\u003eA 1.1 kW motor at 415V drives the 6-stage assembly, achieving a peak head of 35 meters and a flow rate of 220 L\/Min. The motor coupling conforms to NEMA standards, providing a standardised mechanical interface for simplified maintenance.\u003c\/p\u003e\u003cp\u003eWithin each stage, LEXAN floating impellers can move axially against polycarbonate diffusers, helping to prevent sand particles from jamming the rotation. The smooth fluid path through the multiple stages supports consistent water delivery.\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 hydraulic shock during shutdown. 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\u003eLEXAN radial floating impellers are designed to handle sand while reducing internal mechanical binding 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\u003eSix-stage high-capacity hydraulic configuration delivers 35 meters of head for rural and civil water supply\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel external jacket provides structural longevity in aggressive subterranean wells\u003c\/li\u003e\n\u003cli\u003eBuilt-in non-return valve prevents column drainage and protects the motor from reverse rotation stress\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 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 immersion\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50983322550519,"sku":"4SDP 8\/6-W","price":805.97,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-8-6-w-stainless-steel-4-inch-submersible-bore-pump-sandy-groundwater-supply.png?v=1785325855","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-8-6-w-stainless-steel-4-inch-submersible-bore-pump-sandy-groundwater-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
