Outfitted with a highly resilient 100 mm outlet, this premium asset effortlessly handles continuous raw water intake extraction and dense industrial processing tasks. Built specifically to survive aggressive flooded environments, the high-capacity pump removes hazardous raw sewage rapidly to proactively shield local public infrastructure.\u003c\/p\u003e\u003cp\u003eThe massive exterior casting houses an intelligently structured S-Tube impeller that strictly dictates an 85 mm free passage. This vastly expanded spatial clearance aggressively combats the severe blockage risks that traditionally cripple solid-heavy sewage setups. Municipal engineers can confidently rely on this sealed system to continuously process thick, fibrous organic waste streams, fully eliminating the chaotic downtime historically associated with manual unblocking interventions at the plant layer.\u003c\/p\u003e\u003cp\u003ePure kinetic energy is channeled through a highly refined 18.5 kW continuous-duty Grundfos motor linked seamlessly to a standard 415v three-phase grid. This advanced 4-pole drive configuration generates an exceptional maximum head of approximately 26 m alongside a staggering 4986 L\/Min continuous flow limit. The corresponding operational stability sustains incredibly low mechanical vibration signatures, guaranteeing the heavy-duty motor remains fully cooled across demanding daily deployment schedules.\u003c\/p\u003e\u003cp\u003eRemoving all operational dependency on fragile external sensor arrays, the pump natively deploys highly responsive moisture switches and thermal motor-protection thermistors. These reactive internal systems continually verify the integrity of the completely sealed motor cavity. Should excessive thermal buildup or unexpected fluid intrusion threaten the established operational boundaries, the pump instantly alerts operators, successfully saving massive commercial complexes from devastating hardware replacements.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntegrates a state-of-the-art external cable entry plug that allows the fifteen-meter electrical line to be detached safely and efficiently without opening the main motor housing.\u003c\/li\u003e\n\u003cli\u003eFeatures an innovative double shaft seal configured inside a dedicated cartridge assembly, minimizing critical service downtime during rigorous scheduled municipal maintenance.\u003c\/li\u003e\n\u003cli\u003eUtilizes a high-strength secondary shaft sealing ring built from a resilient silicon carbide and carbon friction composition to actively block internal cavity contamination.\u003c\/li\u003e\n\u003cli\u003eManufactured with a massively thick primary casting built entirely from EN 1561 EN-GJL-250 iron, delivering maximum environmental durability across continuous flooded operations.\u003c\/li\u003e\n\u003cli\u003eEngineered to safely function continuously through heavy-density liquid temperatures between ten and forty degrees Celsius within permanent subterranean pumping stations.\u003c\/li\u003e\n\u003cli\u003eDesigned to safely process intense deep fluid extraction at a maximum installation depth of twenty meters while preserving an exact eight bar operating pressure boundary.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880433586423,"sku":"99776318","price":22616.72,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-85-100-185-4-52h-n-51d-a-t-cast-iron-4-pole-wastewater-pump-for-flats-with-s-tube-impeller.png?v=1782109749","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-85-100-185-4-52h-n-51d-a-t-cast-iron-4-pole-wastewater-pump-for-flats-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
