Incorporating a 150 mm inlet and 100 mm outlet, this pump locks in structural integrity for municipal treatment plants. Operating within flooded pits, the asset manages severe fluid surges without compromising infrastructure.\u003c\/p\u003e\u003cp\u003eBuried at the center of this thick metallic housing lies a precision-cast S-Tube impeller governed to maintain a massive 95 mm free passage. This internal clearance proves critical for capturing and relocating solid-heavy municipal sewage without stalling. By neutralizing dense blockage risks at the transfer layer, the circulation loop safely spares public facilities from overflow events.\u003c\/p\u003e\u003cp\u003eSupplying kinetic force is an efficient 22 kW Grundfos 4-pole motor wired into a standard 415v three-phase grid. This assembly outputs an impressive maximum head of approximately 29 m, accompanied by capacities peaking at 4986 L\/Min. The carefully structured fluid velocity paths efficiently harness this energy.\u003c\/p\u003e\u003cp\u003eSolidifying its highly protective profile, the system houses sensitive moisture sensors and motor-protection thermistors natively within the core. These reactive monitoring components constantly trace the sealed motor cavity, building a defensive wall against submersed breaches or thermal overloads.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUtilizes a state-of-the-art cable entry connector that allows the fifteen-meter heavy waterproof cord to be fully disconnected without removing the upper motor casing.\u003c\/li\u003e\n\u003cli\u003eFeatures an easily accessible double shaft seal configured in a dedicated cartridge design, permitting rapid maintenance interventions without heavy specialized equipment.\u003c\/li\u003e\n\u003cli\u003eManufactured with a highly durable secondary shaft seal built from an ultra-tough silicon carbide and carbon friction material configuration to isolate the internal core.\u003c\/li\u003e\n\u003cli\u003eBuilt using premium EN 1561 EN-GJL-250 cast iron across the main pump housing and exterior motor shell to ensure maximum mechanical resilience in flooded environments.\u003c\/li\u003e\n\u003cli\u003eDesigned to seamlessly process immense fluid loads continuously at dense temperature ranges from ten to forty degrees Celsius within permanent municipal networks.\u003c\/li\u003e\n\u003cli\u003eEngineered to safely endure a maximum continuous installation depth of twenty meters while preserving an absolute eight bar internal operating pressure tolerance.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880433848567,"sku":"99776402","price":24536.27,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-95-100-220-4-52h-n-51d-a-t-cast-iron-4-pole-wastewater-pump-for-intake-with-s-tube-impeller.png?v=1782109766","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-95-100-220-4-52h-n-51d-a-t-cast-iron-4-pole-wastewater-pump-for-intake-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
