It processes clean water with suspended sand up to 150 g\/m³ and supports continuous duty for high-volume distribution networks.\u003c\/p\u003e\u003cp\u003eA 3 kW three-phase motor at 415V drives the 27-stage assembly, achieving a peak head of 145 meters and a flow rate of 160 L\/Min. The motor coupling conforms to NEMA standards, providing a standardised mechanical connection for simplified maintenance.\u003c\/p\u003e\u003cp\u003eWithin each stage, LEXAN floating impellers can move axially to accommodate sand particles, helping to protect the polycarbonate diffusers from wear. Consistent operation is maintained throughout the unit's service life.\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 hydraulic assembly from water column weight and back-pressure 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 preventing internal wear and binding\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers reduce turbulence and improve system energy efficiency\u003c\/li\u003e\n\u003cli\u003eTwenty-seven-stage hydraulic assembly delivers 145 meters of head for deep-well recovery and high-flow supply\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel external jacket provides resistance to borehole oxidation and chemical attack\u003c\/li\u003e\n\u003cli\u003eBuilt-in non-return valve protects the hydraulics and motor from backflow and water weight\u003c\/li\u003e\n\u003cli\u003eNEMA-standard coupling simplifies field installation and enables flexible submersible motor selection\u003c\/li\u003e\n\u003cli\u003eChrome-nickel steel suction lantern with robust filter blocks mineral 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":50983322386679,"sku":"4SDP 6\/27-W","price":1436.16,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-6-27-w-stainless-steel-4-inch-submersible-bore-pump-industrial-water-supply.png?v=1785325848","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-6-27-w-stainless-steel-4-inch-submersible-bore-pump-industrial-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
