It handles liquids with suspended sand up to 150 g\/m³ and maintains stable pressure during continuous duty for high-volume storage and irrigation.\u003c\/p\u003e\u003cp\u003eDriven by a 1.5 kW three-phase motor at 415V, the 14-stage assembly achieves a maximum head of 77 meters and a peak flow of 160 L\/Min. The motor coupling conforms to NEMA standards, providing a standardised mechanical connection for simplified maintenance and universal flange compatibility.\u003c\/p\u003e\u003cp\u003eAxial movement of the LEXAN floating impellers within each stage helps to prevent motor seizure when abrasive solids are present. The high-flow system preserves its hydraulic characteristics over an extended 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 protect the hydraulics and motor from back-pressure and water column weight during shutdown. Rated for water up to 35°C, the assembly includes a chrome-nickel steel suction 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 mechanical seizure risk\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers optimize fluid velocity while reducing internal turbulence and energy draw\u003c\/li\u003e\n\u003cli\u003eFourteen-stage radial hydraulic assembly delivers 77 meters of head for high-flow civil water supply\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel external jacket provides a durable shell resistant to corrosive subterranean conditions\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve protects the system from backflow and reduces water hammer impact\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 provides a barrier against oversized mineral particulates\u003c\/li\u003e\n\u003cli\u003eClass F insulation supports prolonged operation in submerged conditions\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50983322321143,"sku":"4SDP 6\/14-W","price":914.43,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-6-14-w-stainless-steel-4-inch-submersible-bore-pump-water-supply.png?v=1785325845","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-6-14-w-stainless-steel-4-inch-submersible-bore-pump-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
