Deployed primarily for aggressive surface water and wastewater drainage, this submersible effluent pump transfers vast quantities of liquid while maintaining structural integrity under submerged pressure.\u003c\/p\u003e\u003cp\u003eThe defensive exterior relies upon EN 1.4301 AISI 304 stainless steel fabrication integrated flawlessly with a durable composite base plate, rendering the system resistant to corrosive agents. Internal electronics are shielded entirely by an advanced double shaft seal system and a specialized intermediate oil chamber that utilizes environmentally friendly, non-toxic special oil.\u003c\/p\u003e\u003cp\u003eAnalyzing the superior internal fluid dynamics, the uniquely cast vortex impeller accommodates substantial particulate matter with its expanded 50 mm free passage clearance. By maintaining continuous flow momentum, the pump smoothly achieves an approximate 14 m maximum head and a maximum flow of roughly 480 L\/Min, transitioning fluid directly through a 50 mm discharge port.\u003c\/p\u003e\u003cp\u003eMinimizing total cost of ownership, the robust motor utilizes an insulation class F thermal rating to halt standard operational degradation. Powered by a heavy-duty 1.21 kW Single Phase 240v electrical architecture, this precise setup guarantees extensive functional lifespans even during uninterrupted surface water management cycles.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBuilt-in thermal overload protection halts motor operation instantly during high-heat anomalies\u003c\/li\u003e\n\u003cli\u003eStrategic inclusion of long-life deep-groove greased-for-life ball bearings ensures frictionless rotation\u003c\/li\u003e\n\u003cli\u003eAutomated functional control is governed by an integrated external level switch\u003c\/li\u003e\n\u003cli\u003eProvided standard with a highly insulated 10 m mains cable for power delivery\u003c\/li\u003e\n\u003cli\u003eSecurely rated with an IP68 enclosure class for permanent sub-surface deployment\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50868919828727,"sku":"96432507","price":1550.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-unilift-ap50b-50-11-a1v-stainless-steel-submersible-drainage-pump-for-groundwater-with-vortex-impeller.png?v=1781689847","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-unilift-ap50b-50-11-a1v-stainless-steel-submersible-drainage-pump-for-groundwater-with-vortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
