This cast iron unit handles municipal sewage transfer while processing effluent within a liquid temperature range of 10°C to 40°C. Maintaining stable performance in submerged pits, the system ensures reliable effluent management for treatment plants and industrial complexes. The technical configuration is intended for high-capacity liquid movement where efficient service is critical for facility protection and infrastructure stability.\u003c\/p\u003e\n\u003cp\u003eTechnical 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 15300 L\/min and achieves a maximum head of approximately 11 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 power cable to facilitate deployment in deep subsurface wastewater handling pits prone to high ingress.\u003c\/p\u003e\n\u003cp\u003eInternal hydraulics are built around a DUAL S-TUBE impeller designed to facilitate the passage of solids up to 110 mm without internal contact. This specialized hydraulic configuration offers high efficiency and significantly reduces the risk of blockages during intensive service in municipal networks. By enabling the free passage of large suspended solids through the housing, the unit maintains volumetric throughput throughout its service life. This impeller setup is specifically engineered for municipal wastewater transfer duties where clog resistance is a critical operational priority.\u003c\/p\u003e\n\u003cp\u003eThe mechanical construction features a heavy-duty cast iron body and motor shell with an IP68 protection rating for depths up to 20 m across an ambient temperature range of -20 to 40°C. Long-term reliability is supported by a double mechanical shaft seal featuring silicon carbide faces in an oil bath to shield the motor. Integrated thermistors and moisture sensors are included to facilitate proactive monitoring of the Class H insulated motor assembly. This pump features standardized DN 250 inlet and DN 250 outlet connections for seamless integration into municipal infrastructure.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDUAL S-TUBE impeller configuration ensures efficient solids handling up to 110 mm and reduces the risk of internal blockages.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron housing and motor shell provide the structural durability required for submerged installations up to 20 m.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal utilizing silicon carbide faces ensures the 17 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 1480 rpm provides the torque needed for high-volume drainage duties.\u003c\/li\u003e\n\u003cli\u003eDN 250 inlet and DN 250 outlet connections allow for high-capacity liquid transfer through standardized plumbing.\u003c\/li\u003e\n\u003cli\u003eBuilt-in cooling jacket enables reliable performance in both dry and submerged installation environments.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880860225783,"sku":"99776811","price":26385.65,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se2110250170452ln51dat-cast-iron-sewage-pump-for-civil-drainage-with-dual-s-tube-impeller.png?v=1782125124","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se2110250170452ln51dat-cast-iron-sewage-pump-for-civil-drainage-with-dual-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
