Verified as a heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.50.11.3 aggressively manages high-volume non-aggressive liquids. The manual three-phase unit functions flawlessly in fixed plumbing systems or as a powerful portable emergency extraction tool.\u003c\/p\u003e\u003cp\u003eTremendous internal pressure generation relies entirely on a heavily upgraded commercial drive core. Wired securely to a 3 x 415 V grid, the massive 1.2 kW motor operates smoothly while drawing just 3.2 Amps. This optimized kinetic transfer forcefully ejects a 533 L\/Min maximum flow directly out of an expanded 50 mm female discharge port, easily overcoming vertical gravity to secure an 18 metre maximum head.\u003c\/p\u003e\u003cp\u003eDefending the primary fluid pathway against abrasive stormwater requires carefully widened physical tolerances. A high-capacity semi-open stainless steel impeller actively handles cloudy mixtures, allowing the safe continuous passage of solid matter up to 12 mm in diameter. This precise clearance ensures aggressive debris processing without mechanical stalling, taking water levels down to a 100 mm minimum.\u003c\/p\u003e\u003cp\u003eAbsolute physical durability is verified by an IP68 classification, safely validating deep underwater deployments down to 7 metres. An integrated motor cooling jacket successfully mitigates core heat, allowing the heavy-duty pump to maintain safe, continuous operations while only partially exposed. Capable of processing liquids between pH 4 and 10, the unit comfortably commands 55°C wastewater environments.\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":50872087478519,"sku":"96001975","price":1400.55,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-unilift-ap12-50-11-3-stainless-steel-three-phase-wastewater-pump-for-basements-with-semi-open-impeller.png?v=1781780081","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-unilift-ap12-50-11-3-stainless-steel-three-phase-wastewater-pump-for-basements-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
