This cast iron unit manages contaminated liquids within a liquid temperature range of 10°C to 40°C, supporting performance in municipal lift stations and treatment plants. Maintaining steady flow behavior during continuous duty is necessary for infrastructure protection and facility maintenance. It is intended for submerged or dry installation in aggressive environments where consistent drainage is required.\u003c\/p\u003e\u003cp\u003ePerformance is driven by a 15 kW four-pole motor on a 415v three-phase supply, producing a rated current of 29 Amps. The system achieves a maximum flow of 15300 L\/min and reaches a maximum head of approximately 10.5 m to satisfy high-volume discharge requirements. Starting is managed via a star-delta method to optimize electrical consumption at a rated speed of 1480 rpm. Electrical deployment is facilitated by a 15-metre S1BN8-F power cable and an IP68 protection rating for depths up to 20 m across an ambient temperature range of -20 to 40°C.\u003c\/p\u003e\u003cp\u003eInternal hydraulics utilize a high-efficiency DUAL S-TUBE impeller designed to facilitate the passage of solids up to 110 mm without internal contact. This specialized hydraulic configuration offers significant clog resistance compared to traditional setups, ensuring reliable wastewater transfer during prolonged service cycles. By enabling the free movement of suspended particles through the housing, the unit maintains its volumetric efficiency throughout its operational life. This impeller configuration is specifically engineered for high-capacity municipal wastewater transfer duties.\u003c\/p\u003e\u003cp\u003eMechanical integrity is reinforced by a heavy-duty cast iron housing and a double mechanical shaft seal utilizing silicon carbide faces in an oil bath. The assembly includes integrated thermistors and moisture sensors to monitor the Class H insulated motor assembly in aggressive environments. Standardized DN 250 inlet and DN 250 outlet connections ensure high-capacity integration into municipal wastewater pipework. This assembly provides the durable foundations necessary for large-scale effluent handling and infrastructure protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHigh-efficiency DUAL S-TUBE impeller manages solids up to 110 mm with significant resistance to internal clogging.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron housing and motor shell ensure structural durability for submerged duty up to 20 m deep.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal utilizing silicon carbide faces ensures the motor remains shielded from ingress.\u003c\/li\u003e\n\u003cli\u003eIntegrated thermistors and moisture sensors enable monitoring of the Class H insulated motor assembly.\u003c\/li\u003e\n\u003cli\u003eFour-pole 15 kW motor operating at 1480 rpm provides the torque needed for high-volume sewage transfer.\u003c\/li\u003e\n\u003cli\u003eDN 250 inlet and DN 250 outlet ports allow for high-capacity liquid transfer through standardized plumbing.\u003c\/li\u003e\n\u003cli\u003eCertified for operation in ambient temperature environments ranging from -20°C to 40°C.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880859996407,"sku":"99776772","price":25541.06,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se2110250150452ln51dat-cast-iron-sewage-pump-for-effluent-handling-with-dual-s-tube-impeller.png?v=1782125121","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se2110250150452ln51dat-cast-iron-sewage-pump-for-effluent-handling-with-dual-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
