It operates safely in groundwater with sand concentrations up to 150 g\/m³ and supports long-term service in clean water environments requiring stable pressure output.\u003c\/p\u003e\u003cp\u003eWith a 0.37 kW motor on a 415V supply, the 13-stage assembly achieves a peak head of 78 meters and a maximum flow of 25 L\/Min. NEMA-standard motor sizing ensures secure mechanical synchronisation between the pump end and motor frame.\u003c\/p\u003e\u003cp\u003eThe hydraulic section uses high-strength LEXAN floating impellers that move axially within the stage casing, helping to maintain operation when sand is present in the water. This design reduces the likelihood of impeller lock compared to fixed-impeller configurations, with polycarbonate diffusers directing flow through each stage.\u003c\/p\u003e\u003cp\u003eAISI 304 stainless steel forms the external jacket, with a chrome-nickel steel delivery casing and a non-return valve housed in the discharge port. This valve prevents column drainage and protects the hydraulics from reverse rotation. The unit is rated for water temperatures up to 35°C and 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 accommodate suspended sand while reducing stage binding likelihood\u003c\/li\u003e\n\u003cli\u003eNon-return valve in the discharge port protects the motor and stage assembly from backflow-related stress\u003c\/li\u003e\n\u003cli\u003eThirteen-stage hydraulic configuration delivers 78 meters of head for high-lift domestic and civil water supply\u003c\/li\u003e\n\u003cli\u003eAISI 304 stainless steel external jacket provides corrosion resistance in aggressive subterranean environments\u003c\/li\u003e\n\u003cli\u003eReinforced polycarbonate diffusers improve hydraulic flow and reduce internal energy losses during continuous duty\u003c\/li\u003e\n\u003cli\u003eNEMA-standard motor coupling enables flexible pairing with various submersible motor brands and models\u003c\/li\u003e\n\u003cli\u003eChrome-nickel steel suction lantern with fine-mesh filter prevents debris ingress and protects internal components\u003c\/li\u003e\n\u003cli\u003eClass F insulation supports prolonged operation in submerged conditions without thermal degradation\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Calpeda","offers":[{"title":"Default Title","offer_id":50983319470327,"sku":"4SDP 1\/13-W","price":890.12,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/calpeda-4sdp-1-13-w-stainless-steel-4-inch-submersible-bore-pump-residential-water-supply.png?v=1785325796","url":"https:\/\/foundationpumps.com.au\/products\/calpeda-4sdp-1-13-w-stainless-steel-4-inch-submersible-bore-pump-residential-water-supply","provider":"Foundation Pumps","version":"1.0","type":"link"}
