Operating as a heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.40.04.3 efficiently clears non-aggressive liquids. The system works effectively as a permanent fixture within drainage pits or as a portable unit for extracting clean and storm water on active sites.\u003c\/p\u003e\u003cp\u003ePhase distribution allows the internal motor to maintain stable rotational torque under pressure. Wired for a 3 x 415 V supply, the robust 0.4 kW drive operates highly efficiently with a strict 1.2 Amps rated draw. It generates a consistent 233 L\/Min maximum flow, discharging directly through a 40 mm female port. Against vertical pipeline resistance, the internal pressure securely sustains a 10 metre maximum head.\u003c\/p\u003e\u003cp\u003eTransporting slightly dirty wastewater requires an unobstructed primary circulation loop. A specialized semi-open stainless steel impeller agitates the fluid, securely managing the transit of solid environmental debris up to 12 mm in diameter. This precise mechanical tolerance eliminates the risk of internal choking, allowing the pump to consistently drop fluid levels down to a 100 mm minimum clearance.\u003c\/p\u003e\u003cp\u003eRated strictly for submerged use, the IP68-classified housing permits deep installations down to 7 metres. An integrated motor cooling jacket constantly dissipates thermal build-up into the passing fluid, enabling the manual unit to operate safely during partial submersion. Built entirely from 304 stainless steel, it comfortably handles liquids ranging from pH 4 to 10 and temperatures up to 55°C.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSupplied with a raw 10-metre power cable specifically tailored for hardwired three-phase commercial integration.\u003c\/li\u003e\n\u003cli\u003eConstructed from premium 304 stainless steel across all wetted parts to permanently resist corrosion.\u003c\/li\u003e\n\u003cli\u003eFeatures an integrated motor cooling jacket for safe, extended operation during partial submersion.\u003c\/li\u003e\n\u003cli\u003eUtilizes a semi-open impeller design capable of continuously passing solid particles up to 12 mm in size.\u003c\/li\u003e\n\u003cli\u003eRated with an IP68 enclosure class to safely permit underwater installations down to a 7-metre maximum depth.\u003c\/li\u003e\n\u003cli\u003eCertified to process a broad range of liquid chemistry, accommodating fluids with a pH value between 4 and 10.\u003c\/li\u003e\n\u003cli\u003eEngineered to safely tolerate 55°C liquid temperatures, and up to 70°C for brief two-minute intervals.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50872087281911,"sku":"96011024","price":862.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-unilift-ap12-40-04-3-stainless-steel-three-phase-wastewater-pump-for-grey-water-with-semi-open-impeller.png?v=1781780070","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-unilift-ap12-40-04-3-stainless-steel-three-phase-wastewater-pump-for-grey-water-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
