This cast iron unit provides a durable solution for sewage collection and effluent transfer where the liquid temperature range is 10°C to 40°C. Maintaining hydraulic throughput during continuous duty is essential for facility protection and long-term civil infrastructure maintenance. It is intended for submerged or dry installation in aggressive environments where reliable performance is a critical operational priority for treatment plant duties.\u003c\/p\u003e\n\u003cp\u003eHydraulic capacity is driven by a 17 kW four-pole motor operating on a 415v three-phase supply with a rated current of 36 Amps. This configuration generates a maximum flow of 4986 L\/min and achieves a maximum head of 24 m to satisfy specific site discharge requirements. The motor operates at 1480 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 lift stations across municipal complexes.\u003c\/p\u003e\n\u003cp\u003eInternal hydraulics are built around an S-TUBE impeller designed to facilitate the passage of solids up to 85 mm without internal contact. This specialized hydraulic configuration offers high efficiency and significantly reduces the risk of blockages during intensive sewage pumping cycles. By enabling the free passage of suspended solids through the housing, the unit maintains volumetric throughput throughout its service life. This impeller setup is specifically engineered for municipal and industrial wastewater transfer duties where clog resistance is a priority for system maintenance.\u003c\/p\u003e\n\u003cp\u003eMechanical construction features 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 from liquid ingress. Integrated thermistors and moisture sensors are included to facilitate proactive monitoring of the Class H insulated motor assembly. Standardized DN 150 inlet and DN 150 outlet connections allow for high-capacity integration into municipal wastewater pipework and civil drainage stations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-efficiency S-TUBE impeller facilitates solids handling up to 85 mm to prevent internal blockages in sewage networks.\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 17 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\u003eFour-pole motor operating at 1480 rpm provides the starting torque required for high-volume sewage handling.\u003c\/li\u003e\n\u003cli\u003eDN 150 inlet and DN 150 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":50880854393079,"sku":"99776278","price":20893.56,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se185150170452hn51dat-cast-iron-sewage-pump-for-effluent-handling-with-s-tube-impeller.png?v=1782125085","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se185150170452hn51dat-cast-iron-sewage-pump-for-effluent-handling-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
