Outfitted with a resilient 150 mm outlet and matched 150 mm inlet, this premium asset handles continuous raw water extraction. Built to survive aggressive flooded environments, the pump removes hazardous sewage rapidly.\u003c\/p\u003e\u003cp\u003eThe massive exterior casting houses an intelligently structured S-Tube impeller that dictates a 95 mm free passage. This expanded spatial clearance actively 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 waste streams without chaotic downtime.\u003c\/p\u003e\u003cp\u003eKinetic energy is channeled through a refined 22 kW continuous-duty Grundfos motor linked to a 415v three-phase grid. This advanced 4-pole drive generates a maximum head of approximately 29 m alongside a staggering 4986 L\/Min continuous flow limit. The resulting operational stability sustains remarkably low mechanical vibration.\u003c\/p\u003e\u003cp\u003eRemoving dependency on fragile external sensor arrays, the pump natively deploys responsive moisture switches and motor-protection thermistors. These reactive systems continually verify the integrity of the sealed motor cavity, instantly alerting operators if boundaries are compromised.\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":50880433946871,"sku":"99776719","price":24536.27,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-95-150-220-4-52h-n-51d-a-t-cast-iron-4-pole-wastewater-pump-for-treatment-with-s-tube-impeller.png?v=1782109773","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-95-150-220-4-52h-n-51d-a-t-cast-iron-4-pole-wastewater-pump-for-treatment-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
