It processes clean water with suspended sand up to 150 g\/m³ and supports continuous duty for civil infrastructure distribution networks.\u003c\/p\u003e\u003cp\u003eA 2.2 kW three-phase motor at 415V drives the 27-stage assembly, achieving a maximum head of 164 meters and a peak flow of 100 L\/Min. The motor coupling conforms to NEMA standards, allowing for reliable synchronisation and standardised mechanical mounting.\u003c\/p\u003e\u003cp\u003eWithin each stage, LEXAN floating impellers can move axially to accommodate sand particles, helping to protect the polycarbonate diffusers from excessive wear. This design supports consistent operation during prolonged high-lift 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 protect the motor from reverse rotation and backflow. Rated for liquid temperatures 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\u003eReinforced polycarbonate diffusers maintain an efficient hydraulic flow path for reduced energy consumption\u003c\/li\u003e\n\u003cli\u003eTwenty-seven-stage hydraulic assembly delivers 164 meters of head for deep-well recovery and building supply\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel external jacket provides resistance to subterranean oxidation and borehole stress\u003c\/li\u003e\n\u003cli\u003eBuilt-in non-return valve protects the internal hydraulics from backflow and reverse rotation stress\u003c\/li\u003e\n\u003cli\u003eNEMA-standard motor coupling enables flexible pairing with standardised submersible 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 continuous duty in deep, fully submerged boreholes\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50983322157303,"sku":"4SDP 4\/27-W","price":1544.62,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-4-27-w-stainless-steel-4-inch-submersible-bore-pump-industrial-water-supply.png?v=1785325836","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-4-27-w-stainless-steel-4-inch-submersible-bore-pump-industrial-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
