The SL1.85.100.130.4.52H.N.51D.A.T overcomes these load challenges by utilizing a robust 100 mm outlet, guaranteeing a stable extraction channel for continuous raw water intake. Deep within flooded subterranean pits, this 13 kW asset reliably clears hazardous commercial wastewater, effectively neutralizing the brutal bottlenecks that continuously threaten underground car parks and large public building complexes.\u003c\/p\u003e\u003cp\u003eForged completely from premium-grade cast iron, the heavily reinforced fluid chamber houses an advanced S-Tube impeller architecture. By purposefully widening the internal volumetric tolerance to enforce a strict 85 mm free passage, the system flawlessly relocates highly contaminated sewage streams. This vital physical scaling allows thick organic sludge to traverse the hydraulic pathways without mechanical hesitation, actively shielding the broader municipal grid from unexpected, catastrophic pipeline blockages.\u003c\/p\u003e\u003cp\u003eKinetic energy originates from a high-capacity 13 kW Grundfos 4-pole motor tethered directly to a 415v three-phase electrical supply. This robust drive assembly translates raw power into profound thermodynamic stability, achieving a maximum head of approximately 23 m alongside an enormous 4986 L\/Min flow rate. The internal momentum evenly distributes continuous friction heat across the heavy casing, preserving smooth circulation loops and keeping operating temperatures strictly regulated during round-the-clock deployments.\u003c\/p\u003e\u003cp\u003eSecuring the critical infrastructure against unseen subsurface threats, the unit embeds sophisticated moisture switches and active motor-protection thermistors directly into its core. These defensive barriers relentlessly monitor the sealed cavity environment for microscopic seal leaks or sudden thermal spikes. By delivering immediate reactive oversight, the system alerts facility engineers early, dramatically lowering reliance on external diagnostic safeguards and minimizing costly manual repair interventions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntegrates an advanced double shaft seal constructed in an easily accessible cartridge layout to ensure rapid field replacements without requiring specialized tools.\u003c\/li\u003e\n\u003cli\u003eFeatures a modular cable entry connector configuration that permits the waterproof fifteen-meter power cord to be detached completely without unbolting the motor top.\u003c\/li\u003e\n\u003cli\u003eEngineered with a robust secondary shaft seal utilizing a highly durable silicon carbide and carbon mechanical friction material combination.\u003c\/li\u003e\n\u003cli\u003eConstructed utilizing a primary fluid housing and motor casing cast exclusively from EN 1561 EN-GJL-250 grade iron to guarantee maximum submerged resilience.\u003c\/li\u003e\n\u003cli\u003eFully rated to handle continuous operations in dense liquid temperature ranges spanning from ten up to forty degrees Celsius within permanent municipal installations.\u003c\/li\u003e\n\u003cli\u003eConfigured to safely process heavy contaminated fluids at a maximum installation depth of twenty meters while preserving a strictly controlled eight bar operating pressure boundary.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880433094903,"sku":"99776095","price":19879.97,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-85-100-130-4-52h-n-51d-a-t-cast-iron-4-pole-sewage-pump-for-garages-with-s-tube-impeller.png?v=1782109742","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-85-100-130-4-52h-n-51d-a-t-cast-iron-4-pole-sewage-pump-for-garages-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
