The SL1.85.100.110.4.52H.N.51D.A.T tackles these severe demands via its 150 mm inlet and 100 mm outlet. This submersible configuration removes raw sewage rapidly, shielding valuable municipal infrastructure from flooding.\u003c\/p\u003e\n\u003cp\u003eA central mechanical advantage rests in its cast iron fluid chamber containing a balanced S-Tube impeller. By scaling the internal clearance to permit an 85 mm free passage, the pump prevents thick solid-laden waste from accumulating. This capability is absolutely crucial for preventing devastating system bottlenecks across the grid.\u003c\/p\u003e\n\u003cp\u003ePowering this extreme internal velocity is a durable 11 kW Grundfos 4-pole motor running on a 415v three-phase grid. This assembly converts electrical energy into heavy fluid motion, reaching a maximum head of approximately 21 m and an immense 4986 L\/Min flow. Such raw power builds exceptional thermodynamic stability across long cycles.\u003c\/p\u003e\n\u003cp\u003eProtecting this asset against submersed threats, the pump incorporates vital moisture sensors and motor-protection thermistors directly into its core. These defensive barriers track the sealed casing for leaks or thermal overloading, proactively isolating the system before severe mechanical failure disrupts the primary distribution loop.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFeatures an advanced double shaft seal constructed in a highly modular cartridge format to permit safe fluid replacements without requiring specialized heavy tools.\u003c\/li\u003e\n\u003cli\u003eIncorporates a dedicated quick-release cable entry connector that actively allows the main power cord to be fully disconnected without removing the upper motor cover.\u003c\/li\u003e\n\u003cli\u003eConstructed using an EN 1561 EN-GJL-250 cast iron motor casing and pump volute to assure maximum mechanical resilience and passive heat dissipation in submersed settings.\u003c\/li\u003e\n\u003cli\u003eUtilizes a profoundly durable secondary shaft seal constructed from a tough silicon carbide and carbon friction material combination to shield the internal core.\u003c\/li\u003e\n\u003cli\u003eRated to safely operate at a maximum continuous installation depth of twenty meters while preserving an absolute eight bar maximum internal operating pressure tolerance.\u003c\/li\u003e\n\u003cli\u003eEngineered to easily endure extreme continuous submerged fluid temperatures ranging from ten up to forty degrees Celsius within unyielding municipal processing setups.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50877323018487,"sku":"99776058","price":18124.72,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-85-100-110-4-52h-n-51d-a-t-cast-iron-4-pole-wastewater-pump-for-intake-with-s-tube-impeller.png?v=1781953997","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-85-100-110-4-52h-n-51d-a-t-cast-iron-4-pole-wastewater-pump-for-intake-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
