This cast iron unit handles contaminated liquids within a liquid temperature range of 10°C to 40°C, supporting performance in lift stations and treatment plants. The heavy-duty design facilitates permanent submerged service while maintaining high volumetric throughput in aggressive environments. It is intended for civil infrastructure requiring reliable wastewater management across an ambient temperature range of -20°C to 40°C.\u003c\/p\u003e\n\u003cp\u003eTechnical capacity is driven by a 22 kW four-pole motor operating on a 415v three-phase supply with a rated current of 41 Amps. This configuration generates a maximum flow of 8340 L\/min and achieves a maximum head of 23 m to satisfy high-load evacuation requirements. The motor operates at 1476 rpm and utilizes a star-delta starting method to manage peak electrical loads during initial activation. Power is distributed through a 15-metre power cable to facilitate deployment in deep subsurface wastewater handling pits and high-capacity municipal complexes prone to high ingress.\u003c\/p\u003e\n\u003cp\u003eInternal centrifugal pathways utilize an S-TUBE impeller configuration to facilitate the passage of solids up to 110 mm without internal contact. This hydraulic design ensures high efficiency and reliable wastewater transfer, reducing the risk of internal blockages during continuous duty in municipal networks. The S-TUBE impeller is engineered for durability, maintaining volumetric efficiency throughout thousands of operating hours in aggressive sewage. This configuration is specifically intended for municipal wastewater transfer where system reliability is critical for infrastructure maintenance and civil works.\u003c\/p\u003e\n\u003cp\u003eMechanical integrity is reinforced by a heavy-duty cast iron housing and an IP68 protection rating for depths up to 20 m. Reliability is anchored by a double mechanical shaft seal with silicon carbide faces in an oil bath to protect the motor from liquid ingress. This model includes integrated thermistors and moisture sensors for proactive monitoring of the Class H insulated motor assembly. Standardized DN 200 inlet and DN 200 outlet connections allow for standardized integration into municipal wastewater pipework and civil drainage infrastructure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eS-TUBE impeller design enables the passage of solids up to 110 mm with significant resistance to internal clogging.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron housing and motor shell provide the structural durability required for submerged installations up to 20 m.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal utilizing silicon carbide faces ensures the 22 kW motor remains shielded from ingress.\u003c\/li\u003e\n\u003cli\u003eInternal moisture sensors and thermistors provide monitoring to safeguard the Class H insulated motor assembly.\u003c\/li\u003e\n\u003cli\u003eFour-pole motor configuration operating at 1476 rpm provides the torque needed for high-flow wastewater transfer.\u003c\/li\u003e\n\u003cli\u003eDN 200 inlet and DN 200 outlet connections allow for high-capacity liquid transfer through standardized plumbing.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure rating confirms the system is suitable for permanent immersion in aggressive submerged environments.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880859209975,"sku":"99776639","price":28578.02,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se1110200220452mn51dat-cast-iron-sewage-pump-for-wastewater-handling-with-s-tube-impeller.png?v=1782125116","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se1110200220452mn51dat-cast-iron-sewage-pump-for-wastewater-handling-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
