The SL1.110.200.200.4.52M.N.51D.A.T tackles these extreme loads via an enormous 200 mm inlet paired with a 200 mm outlet. Operating within deeply flooded pits, this submersible pump rapidly clears raw sewage, effectively neutralizing bottleneck risks across municipal complexes.\u003c\/p\u003e\u003cp\u003eForged from thick EN 1561 EN-GJL-250 cast iron, the chamber securely houses an S-Tube impeller accurately calibrated to guarantee a massive 110 mm free passage. This expanded internal clearance effortlessly permits solid-laden sludge to pass without stalling. By permanently eliminating mechanical choke points, the circulation loop safely secures directional flow purity.\u003c\/p\u003e\u003cp\u003eGenerating immense kinetic force is a durable 20 kW Grundfos 4-pole motor drawing cleanly from a 415v three-phase grid. This assembly converts raw power into heavy fluid motion, reaching a maximum head of approximately 21 m and an incredible 8340 L\/Min peak flow rate. Highly optimized interior pathways smoothly dissipate intense thermodynamic heat loads.\u003c\/p\u003e\u003cp\u003eGuarding against submersed failures, the system incorporates moisture switches and active motor-protection thermistors directly into its core. These autonomous safety mechanisms relentlessly scan the sealed cavity, providing an immediate reactive defense if unwanted liquid breaches the primary casing boundaries.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFeatures a remarkably accessible double shaft seal configured inside a dedicated, modular cartridge design, actively permitting rapid primary maintenance interventions.\u003c\/li\u003e\n\u003cli\u003eUtilizes a highly advanced external cable entry connector plug that safely allows the heavy-duty fifteen-meter waterproof cord to be disconnected without unbolting the top.\u003c\/li\u003e\n\u003cli\u003eBuilt using incredibly thick, premium EN 1561 EN-GJL-250 cast iron across the main primary pump housing and exterior protective motor shell to physically ensure absolute resilience.\u003c\/li\u003e\n\u003cli\u003eManufactured with a highly durable secondary shaft seal heavily built from an ultra-tough silicon carbide and carbon friction material configuration to protect the internal core.\u003c\/li\u003e\n\u003cli\u003eDesigned to seamlessly process immense raw fluid volumetric loads continuously at dense temperature ranges actively spanning from exactly ten to forty degrees Celsius.\u003c\/li\u003e\n\u003cli\u003eEngineered to safely endure a thoroughly tested maximum continuous underwater installation depth of exactly twenty meters while maintaining a strict eight bar internal operating pressure.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880434307319,"sku":"99776616","price":27720.91,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-110-200-200-4-52m-n-51d-a-t-cast-iron-4-pole-sewage-pump-for-municipal-with-s-tube-impeller.png?v=1782109789","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-110-200-200-4-52m-n-51d-a-t-cast-iron-4-pole-sewage-pump-for-municipal-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
