This cast iron unit is built for intensive duty in large municipal complexes, handling contaminated fluids within a liquid temperature range of 10°C to 40°C. Maintaining network stability during peak ingress periods is essential for facility protection and infrastructure management. It provides a robust solution for subsurface collection pits where performance must remain stable across high volumes.\u003c\/p\u003e\u003cp\u003eTechnical performance is delivered by a 22 kW four-pole motor on a 415v three-phase supply, producing a rated current of 41 Amps. The pump generates a maximum flow of 14160 L\/min and reaches a maximum head of approximately 13.3 m for efficient evacuation of municipal wastewater and effluent. Starting is managed via a star-delta method to protect the motor assembly, while the 1476 rpm rated speed ensures torque stability. Deployment in deep subsurface pits is supported by a 15-metre power cable and an IP68 protection rating for depths up to 20 m.\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 contact. This specialized hydraulic configuration significantly reduces the risk of internal blockages during intensive sewage pumping duties. By enabling large suspended particles to move freely through the housing, the unit maintains its volumetric efficiency over thousands of operational hours. This impeller configuration is specifically engineered for high-capacity municipal wastewater transfer where maintaining throughput is a critical priority.\u003c\/p\u003e\u003cp\u003eStructural integrity is reinforced by a heavy-duty cast iron body with 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 assembly from liquid ingress. Integrated thermistors and moisture sensors are included to facilitate proactive monitoring of the Class H insulated motor assembly in aggressive environments. This pump features standardized DN 250 inlet and DN 250 outlet connections to ensure compatibility with high-capacity municipal wastewater pipework.\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 22 kW motor configuration operating at 1476 rpm provides the torque needed for high-volume effluent pumping.\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\u003eIP68 enclosure rating confirms the system is suitable for permanent immersion in aggressive wastewater environments.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880861503735,"sku":"99776926","price":29004.34,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se2110250220452ln51dat-cast-iron-sewage-pump-for-wastewater-handling-with-dual-s-tube-impeller.png?v=1782125130","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se2110250220452ln51dat-cast-iron-sewage-pump-for-wastewater-handling-with-dual-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
