This 6-pole cast iron unit manages municipal sewage and effluent within a liquid temperature range of 10°C to 40°C, supporting performance in treatment plants and high-flow stations. 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 varying liquid levels.\u003c\/p\u003e\n\u003cp\u003ePerformance is delivered by a 13 kW six-pole motor on a 415v three-phase supply, producing a rated current of 29 Amps. The system achieves a maximum flow of 18000 L\/min and reaches a maximum head of approximately 8.5 m for high-load discharge duties in large collection pits. Starting is managed via a star-delta method to protect the electrical assembly, while the 980 rpm rated speed ensures steady torque during high-volume duties. A 15-metre S1BN8-F power cable is provided for installation in deep collection pits and subsurface complexes across an ambient temperature range of -20 to 40°C.\u003c\/p\u003e\n\u003cp\u003eInternal centrifugal pathways utilize a high-efficiency DUAL S-TUBE impeller configuration to facilitate the passage of solids up to 125 mm without internal contact. This specialized hydraulic setup significantly reduces the risk of internal blockages during intensive sewage pumping cycles in municipal networks. By enabling large particles to pass freely 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 where maintaining throughput is critical for infrastructure maintenance.\u003c\/p\u003e\n\u003cp\u003eStructural integrity is anchored by a heavy-duty cast iron body with an IP68 protection rating for depths up to 20 m. Motor protection is provided by a double mechanical shaft seal utilizing silicon carbide faces in an oil bath to shield the assembly from liquid ingress. Integrated thermistors and moisture sensors are included to facilitate proactive monitoring of the Class H insulated motor assembly. Standard DN 300 inlet and DN 300 outlet connections ensure high-capacity integration into municipal wastewater pipework and standardized civil drainage systems.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-efficiency DUAL S-TUBE impeller manages solids up to 125 mm with significant resistance to internal clogging.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron housing and motor shell support installation in deep submerged pits up to 20 m.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with silicon carbide faces ensures the 13 kW motor remains shielded from ingress.\u003c\/li\u003e\n\u003cli\u003eIntegrated thermistors and moisture sensors enable real-time monitoring of the Class H insulated motor assembly.\u003c\/li\u003e\n\u003cli\u003eSix-pole motor operating at 980 rpm provides the starting torque required for high-volume sewage collection.\u003c\/li\u003e\n\u003cli\u003eDN 300 inlet and DN 300 outlet connections allow for high-capacity liquid transfer through standardized pipework.\u003c\/li\u003e\n\u003cli\u003eBuilt-in cooling jacket enables reliable performance in both dry and submerged installation environments.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880862355703,"sku":"99777006","price":33036.04,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se2125300130652en51dat-cast-iron-sewage-pump-for-sewage-transfer-with-dual-s-tube-impeller.png?v=1782125133","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se2125300130652en51dat-cast-iron-sewage-pump-for-sewage-transfer-with-dual-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
