Designed around a prominent 100 mm outlet, this high-volume submersible wastewater pump is specifically optimized for deep underground car parks and intense industrial sectors moving massive volumes of raw sewage daily. It thrives under relentless fluid demands, firmly establishing a highly reliable transfer baseline for essential municipal treatment facilities.\u003c\/p\u003e\u003cp\u003eGoverning the primary fluid chamber is an advanced S-Tube impeller meticulously calibrated to ensure a permanent 85 mm free passage tolerance. This spacious structural clearance permits highly dense commercial sludge and abrasive fibrous debris to pass completely unrestricted. By actively preventing suspended heavy solids from accumulating inside the volute, the local extraction infrastructure consistently maintains perfect flow purity across the entire pressurized commercial network.\u003c\/p\u003e\u003cp\u003eCommanding this intense fluid motion is an incredibly durable 17 kW continuous-duty Grundfos 4-pole motor. Operating strictly on a 415v three-phase grid, this powerhouse reliably pushes a maximum head of approximately 24 m alongside a vast 4986 L\/Min peak flow rate. The integrated mechanical configuration absorbs and dissipates extreme thermodynamic heat loads smoothly across the rugged iron exterior, effectively preventing the internal drive assembly from stalling out under heavy environmental duress.\u003c\/p\u003e\u003cp\u003eProactively shielding against catastrophic mechanical failure, the core framework inherently relies on integrated moisture switches and advanced motor-protection thermistors. These internal safety layers relentlessly monitor the sealed cavity climate, executing an immediate reactive defense protocol if unwanted liquids breach the casing boundaries. This continuous native oversight radically extends the functional lifespan of the unit by mitigating risks before they can propagate across the system.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEquipped with a modular quick release cable entry plug that effectively allows the heavy-duty power cord to be securely detached without unbolting the motor top.\u003c\/li\u003e\n\u003cli\u003eIncorporates a highly service-friendly double shaft seal structured in an exclusive cartridge layout to permit rapid field replacements without specialized mechanical tools.\u003c\/li\u003e\n\u003cli\u003eConstructed with a primary pump volute and upper motor casing cast completely from EN 1561 EN-GJL-250 grade iron for optimal submerged environmental resilience.\u003c\/li\u003e\n\u003cli\u003eEngineered with a highly reliable secondary shaft seal utilizing an advanced silicon carbide and carbon mechanical friction material block to stop moisture leaks.\u003c\/li\u003e\n\u003cli\u003eFully rated to handle relentless extraction operations in dense liquid temperature ranges spanning from ten to forty degrees Celsius within completely flooded installations.\u003c\/li\u003e\n\u003cli\u003eConfigured to handle extreme fluid transfers securely at a maximum installation depth of twenty meters while safely maintaining a strict eight bar maximum operating pressure.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880433225975,"sku":"99776238","price":21705.09,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-85-100-170-4-52h-n-51d-a-t-cast-iron-4-pole-sewage-pump-for-industries-with-s-tube-impeller.png?v=1782109746","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-85-100-170-4-52h-n-51d-a-t-cast-iron-4-pole-sewage-pump-for-industries-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
