This cast iron unit provides a durable solution for drainage stations and treatment plants where the liquid temperature range reaches 10°C to 40°C. Maintaining hydraulic throughput during continuous duty is essential for facility protection and long-term infrastructure maintenance. It is intended for submerged or dry installation in aggressive environments where consistent drainage infrastructure support is required for civil works and high-volume evacuation.\u003c\/p\u003e\u003cp\u003eThis model operates on a 415v three-phase supply and utilizes a 22 kW motor with a rated current of 41 Amps. The system achieves a maximum flow of 4986 L\/min and produces a maximum head of 29 m for high-load discharge duties. Starting is managed via a star-delta method to protect the electrical assembly, while the 1476 rpm rated speed ensures torque stability during intensive duty cycles. A 15-metre power cable is provided for installation in deep collection pits and large-scale wastewater networks across an ambient temperature range of -20°C to 40°C.\u003c\/p\u003e\u003cp\u003eInternal hydraulics are built around an S-TUBE impeller designed to facilitate the passage of solids up to 95 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 consistent volumetric throughput throughout its service life. This impeller setup is specifically engineered for municipal and industrial wastewater transfer duties where maintaining flow is critical for system reliability.\u003c\/p\u003e\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. 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. This pump features standardized DN 150 inlet and DN 100 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 facilitates solids handling up to 95 mm to prevent internal blockages in sewage systems.\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 22 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 1476 rpm provides the starting torque required for drainage infrastructure duties.\u003c\/li\u003e\n\u003cli\u003eDN 150 inlet and DN 100 outlet connections 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.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880854851831,"sku":"99776413","price":23512.24,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se195100220452hn51dat-cast-iron-sewage-pump-for-sewage-transfer-with-s-tube-impeller.png?v=1782125092","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se195100220452hn51dat-cast-iron-sewage-pump-for-sewage-transfer-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
