Recognized as an automatic heavy duty, submersible stainless steel grey water pump, the Grundfos UNILIFT AP12.40.04.A3 continuously handles fluid accumulation. Powered by a three-phase connection, it expertly manages clean water, storm water, and slightly dirty run-off across light industrial settings.\u003c\/p\u003e\u003cp\u003eThe system relies on an efficient 3 x 415 V electrical configuration to guarantee smooth kinetic conversion. Pulling just 1.2 Amps, the 0.4 kW motor actively maintains high torque delivery without fluctuation. The hydraulic chamber forces a maximum flow of 233 L\/Min securely through a 40 mm female outlet, efficiently establishing a 10 metre maximum head during upward extraction paths.\u003c\/p\u003e\u003cp\u003eInternal blockage prevention is achieved through meticulous fluid pathway geometry. The unit utilizes a dynamic semi-open stainless steel impeller that allows solid particles up to 12 mm to wash through the volute safely. This clearance protects the main drive shaft from abrasive wear while ensuring the automatic system can reliably pump water down to a minimum level of 100 mm.\u003c\/p\u003e\u003cp\u003eThe completely sealed IP68 enclosure safely withstands underwater installations down to a depth of 7 metres. A built-in motor cooling jacket effectively regulates core temperatures, providing the flexibility to operate safely during partial exposure. Governed completely by an attached float switch, the pump processes 55°C wastewater and safely interacts with liquid pH levels between 4 and 10.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEquipped with a tethered float switch to provide fully automated start and stop drainage operation.\u003c\/li\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 304 stainless steel across all wetted parts to permanently resist industrial 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 depth.\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":50872087314679,"sku":"96011025","price":1071.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-unilift-ap12-40-04-a3-stainless-steel-auto-wastewater-pump-for-pits-with-semi-open-impeller.png?v=1781780072","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-unilift-ap12-40-04-a3-stainless-steel-auto-wastewater-pump-for-pits-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
