This unit facilitates stable liquid movement in environments where consistent ingress and varying demand levels are the norm. It supports permanent submerged service and is capable of processing effluent with a liquid temperature range of 10°C to 40°C. For facilities managing high-volume discharge, this cast iron assembly provides a durable solution for drainage stations and treatment plant duties.\u003c\/p\u003e\u003cp\u003eThis four-pole configuration operates on a 415v three-phase supply, delivering 10 kW of power with a rated current of 21 Amps. The pump achieves a maximum flow of 4986 L\/min and reaches a maximum head of 19 m for high-load evacuation. Initial activation is managed via a star-delta starting method to optimize electrical consumption and ensure torque stability at a rated speed of 1482 rpm. Electrical deployment is facilitated by a 15-metre power cable suitable for installation in deep collection pits and large-scale industrial complexes.\u003c\/p\u003e\u003cp\u003eInternal centrifugal pathways utilize a high-efficiency S-TUBE impeller designed to manage the passage of solids up to 85 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 efficiency over prolonged operation. The S-TUBE impeller is specifically engineered for municipal wastewater transfer where maintaining throughput is critical for infrastructure stability.\u003c\/p\u003e\u003cp\u003eMechanical construction consists of a heavy-duty cast iron body and motor shell with an IP68 protection rating for depths up to 20 m. Long-term reliability is anchored by a double mechanical shaft seal featuring silicon carbide faces in an oil bath to shield the motor assembly. Integrated thermistors and moisture sensors are included to facilitate proactive monitoring of the Class H insulated motor assembly. This assembly features standardized DN 150 inlet and DN 150 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 S-TUBE impeller manages solids up to 85 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 1482 rpm provides the torque needed for processing high-volume effluent transfer.\u003c\/li\u003e\n\u003cli\u003eDN 150 inlet and DN 150 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":50880853115127,"sku":"99776042","price":17516.97,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se185150100452hn51dat-cast-iron-sewage-pump-for-effluent-handling-with-s-tube-impeller.png?v=1782125078","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se185150100452hn51dat-cast-iron-sewage-pump-for-effluent-handling-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
