This unit facilitates stable liquid movement in environments where consistent ingress and high flow levels are the norm. It is capable of processing contaminated effluent with a liquid temperature range of 10°C to 40°C and supports permanent submerged service. For facilities managing high-volume discharge, this assembly provides a durable solution for lift stations and treatment plant duties.\u003c\/p\u003e\n\u003cp\u003eTechnical capacity is provided by a 20 kW four-pole motor operating on a 415v three-phase supply with a rated current of 39 Amps. This configuration generates a maximum flow of 14160 L\/min and achieves a maximum head of approximately 12.4 m to satisfy specific site evacuation requirements. The motor operates at 1478 rpm and utilizes a star-delta starting method to manage peak electrical loads during initial activation. Power is distributed through a 15-metre S1BN8-F power cable to facilitate deployment in deep subsurface wastewater handling pits and large complexes.\u003c\/p\u003e\n\u003cp\u003eInternal hydraulics utilize a high-efficiency DUAL S-TUBE impeller designed to manage the passage of solids up to 110 mm without inducing internal blockages. This specialized configuration provides significant clog resistance compared to traditional hydraulics, ensuring reliable wastewater transfer during intensive service cycles. By enabling the free movement of suspended particles through the housing, the unit maintains its volumetric throughput over thousands of operational hours. This impeller setup is specifically engineered for high-capacity municipal wastewater transfer duties.\u003c\/p\u003e\n\u003cp\u003eMechanical construction features a heavy-duty cast iron pump body and motor shell with an IP68 protection rating for depths up to 20 m and an ambient temperature range of -20 to 40°C. Reliability is anchored by a double mechanical shaft seal featuring silicon carbide faces in an oil bath for motor protection. This model includes integrated thermistors and moisture sensors for proactive monitoring of the Class H insulated motor assembly. Standard DN 250 inlet and DN 250 outlet connections allow for seamless integration into municipal wastewater infrastructure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDUAL S-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.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal utilizing silicon carbide faces ensures the 20 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 1478 rpm provides the torque needed for high-volume wastewater handling.\u003c\/li\u003e\n\u003cli\u003eDN 250 inlet and DN 250 outlet connections allow for high-capacity liquid transfer through standardized pipework.\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":50880860750071,"sku":"99776890","price":28073.94,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se2110250200452ln51dat-cast-iron-sewage-pump-for-effluent-handling-with-dual-s-tube-impeller.png?v=1782125128","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se2110250200452ln51dat-cast-iron-sewage-pump-for-effluent-handling-with-dual-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
