It is structurally designed to handle clean water, storm water, and slightly dirty wastewater across both domestic and light industrial applications. The unit offers flexible deployment capabilities, functioning efficiently within permanent plumbing installations or acting as a portable drainage asset for temporary fluid relocation.\u003c\/p\u003e\u003cp\u003eHydraulic performance is driven by a highly efficient 1.1 kW motor mechanism. Powered via a 1 x 240 V single-phase electrical supply, the robust core operates with a rated draw of 8.5 Amps. Fluid is discharged through a 50 mm female threaded connection, allowing the internal volute to securely output a maximum flow of 500 L\/Min. During vertical extraction cycles, the unit effectively scales the fluid column to establish a 17 metre maximum head.\u003c\/p\u003e\u003cp\u003eContinuous operation in dirty environments requires a fortified internal circulation pathway. The pump incorporates a precision semi-open stainless steel impeller that allows the safe transit of solid environmental particles up to 12 mm in diameter. This specific geometric clearance prevents suspended matter from causing rotational jams while permitting the system to safely draw standing water down to a 100 mm minimum pumping level.\u003c\/p\u003e\u003cp\u003eBuilt entirely from premium 304 stainless steel, the IP68-rated motor permits submerged underwater installations down to a 7-metre maximum depth. An integrated motor cooling jacket consistently dissipates internal heat, allowing for extended continuous operation even when only partially submerged. The pump safely processes fluids with a pH between 4 and 10 and handles liquid temperatures up to 55°C, with a brief tolerance of 70°C for two-minute intervals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eConstructed entirely from premium 304 stainless steel across all wetted components to 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\u003eCapable of continuous extraction down to a minimum pumping level of exactly 100 mm.\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":50872087216375,"sku":"96001961","price":1446.7,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-unilift-ap12-50-11-1-stainless-steel-psc-motor-wastewater-pump-for-catchments-with-semi-open-impeller.png?v=1781780066","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-unilift-ap12-50-11-1-stainless-steel-psc-motor-wastewater-pump-for-catchments-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
