It handles clean water with sand concentrations up to 150 g\/m³ and supports continuous duty for residential distribution and garden irrigation.\u003c\/p\u003e\u003cp\u003eDriven by a 0.37 kW three-phase motor at 415V, the 5-stage assembly achieves a maximum head of 29 meters and a flow rate of 100 L\/Min. The motor coupling conforms to NEMA standards, allowing for reliable mechanical synchronisation with various submersible motor frames.\u003c\/p\u003e\u003cp\u003eWithin the hydraulic section, LEXAN floating impellers move axially against diffusers to accommodate sand particles, helping to prevent mechanical blockage and reduce abrasive wear over time. Reinforced polycarbonate diffusers direct the flow path during high-capacity transfer cycles.\u003c\/p\u003e\u003cp\u003eAISI 304 stainless steel forms the external jacket, with a delivery casing incorporating a built-in non-return valve to prevent backflow damage. The suction lantern and filter are manufactured from chrome-nickel steel. Rated for liquid temperatures up to 35°C, the assembly features Class F insulation and IP68 protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLEXAN radial floating impellers facilitate sand passage while reducing mechanical seizure risk\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers offer strength and reduced internal friction losses\u003c\/li\u003e\n\u003cli\u003eFive-stage radial configuration delivers 29 meters of head for high-flow residential and civil water distribution\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel external jacket provides resistance to borehole oxidation and chemical attack\u003c\/li\u003e\n\u003cli\u003eIntegrated non-return valve in the delivery casing protects the hydraulics from backflow and reverse water weight\u003c\/li\u003e\n\u003cli\u003eNEMA-standard flange coupling simplifies field installation and allows flexible submersible motor selection\u003c\/li\u003e\n\u003cli\u003eChrome-nickel steel suction lantern with integrated filter blocks mineral debris from the intake stages\u003c\/li\u003e\n\u003cli\u003eClass F insulation and IP68 protection support continuous duty in fully submerged wells\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50983321960695,"sku":"4SDP 4\/5-W","price":608.69,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-4-5-w-stainless-steel-4-inch-submersible-bore-pump-water-supply.png?v=1785325827","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-4-5-w-stainless-steel-4-inch-submersible-bore-pump-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
