The SE2.110.250.100.4.52L.N.51D.A.T Submersible Wastewater Pump provides a robust solution for large-scale municipal networks managing liquid temperatures from 10°C to 40°C. Maintaining network stability during peak ingress periods requires consistent volumetric throughput and reliable submerged operation for facility protection. This cast iron unit is intended for permanent installation in aggressive environments.\u003c\/p\u003e\u003cp\u003eTechnical specifications for this four-pole assembly include a 10 kW motor operating on a 415v three-phase supply with a rated current of 21 Amps. The system achieves a maximum flow of 12480 L\/min and reaches a maximum head of approximately 8.2 m to satisfy large-bore drainage requirements. Starting is managed via a star-delta method to optimize electrical consumption at a rated speed of 1481 rpm. A 15-metre power cable is included to facilitate deployment in deep subsurface pits and collection stations.\u003c\/p\u003e\u003cp\u003eInternal fluid paths utilize a high-efficiency DUAL S-TUBE impeller configuration to facilitate the passage of solids up to 110 mm without contact. This hydraulic setup significantly reduces the risk of internal blockages during intensive sewage pumping cycles in municipal complexes. By enabling large particles to move freely through the cast iron housing, the unit maintains its volumetric efficiency over thousands of service hours. This impeller setup is specifically engineered for high-volume liquid handling where system durability is critical for maintenance.\u003c\/p\u003e\u003cp\u003eStructural integrity is anchored by a heavy-duty cast iron body with an IP68 protection rating for depths up to 20 m and an ambient temperature range of -20 to 40°C. Motor protection is provided by a double mechanical shaft seal utilizing silicon carbide faces in an oil bath to shield the motor. Integrated thermistors and moisture sensors enable proactive monitoring of the Class H insulated motor assembly. Standard DN 250 inlet and DN 250 outlet connections ensure high-capacity pipework compatibility in municipal wastewater systems.\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 protected 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 10 kW motor operating at 1481 rpm provides the torque needed for processing high-volume effluent 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":50880859406583,"sku":"99776678","price":24283.55,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se2110250100452ln51dat-cast-iron-sewage-pump-for-civil-drainage-with-dual-s-tube-impeller.png?v=1782125118","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se2110250100452ln51dat-cast-iron-sewage-pump-for-civil-drainage-with-dual-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
