It handles clean water, storm water, and slightly dirty wastewater across domestic and light industrial environments. 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 relies on an efficient 0.4 kW motor. Powered via a 1 x 240 V single-phase electrical supply, the core operates with a rated draw of 3.1 Amps. Fluid is discharged through a 40 mm female threaded connection, allowing the volute to securely output a maximum flow of 233 L\/Min. During vertical extraction cycles, the unit effectively scales the fluid column to establish a 10 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 particles up to 12 mm in diameter. This geometric clearance prevents suspended matter from causing rotational jams. The manual configuration permits the system to draw standing water down to a 100 mm minimum pumping level.\u003c\/p\u003e\u003cp\u003eConstructed entirely from 304 stainless steel, the IP68-rated motor permits submerged underwater installations down to a 7-metre maximum depth. An integrated cooling jacket dissipates internal heat, allowing for extended continuous operation when partially submerged. The pump processes fluids with a pH between 4 and 10 and handles liquid temperatures up to 55°C, with a brief thermal tolerance of 70°C for two minutes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFeatures a heavy-duty brass cable union to strictly isolate the primary electrical feed from ambient moisture intrusion.\u003c\/li\u003e\n\u003cli\u003eRated with an internal Class F insulation threshold to safely tolerate heavy electrical load fluctuations.\u003c\/li\u003e\n\u003cli\u003eUtilizes a Permanent Split Capacitor (PSC) motor architecture to ensure smooth rotational startup sequences.\u003c\/li\u003e\n\u003cli\u003eEquipped with internal thermal protection circuitry that acts as an immediate safety cutoff to prevent coil burnout.\u003c\/li\u003e\n\u003cli\u003ePre-installed with a 10-metre power supply cable terminating in a standard single-phase plug for immediate deployment.\u003c\/li\u003e\n\u003cli\u003eCertified with C-Tick and CE compliance markings to guarantee strict adherence to recognized environmental standards.\u003c\/li\u003e\n\u003cli\u003eUnit possesses a net weight of 11.6 kg, ensuring stable positioning during portable deployment across varied catchments.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50872086692087,"sku":"96011032","price":968.8,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-unilift-ap12-40-04-1-stainless-steel-manual-wastewater-pump-for-sumps-with-semi-open-impeller.png?v=1781780053","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-unilift-ap12-40-04-1-stainless-steel-manual-wastewater-pump-for-sumps-with-semi-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
