This assembly is engineered for municipal sewage transfer where structural durability prevents damage from suspended debris in large collection pits. Maintaining performance during permanent immersion, the cast iron build ensures resistance to wear while processing effluent within a liquid temperature range of 10°C to 40°C. The unit is built for intensive drainage service where material integrity is a primary requirement for infrastructure protection.\u003c\/p\u003e\u003cp\u003eHydraulic capacity is provided by an 11 kW four-pole motor on a 415v three-phase supply, producing a rated current of 22 Amps. The system generates a maximum flow of 6180 L\/min and reaches a maximum head of 15 m for efficient evacuation of contaminated liquids. A star-delta starting method manages electrical loads during initial activation, while the 1481 rpm rated speed ensures torque stability. Power is distributed through a 15-metre power cable to support deployment in deep-pit infrastructure and subsurface wastewater handling networks prone to high ingress.\u003c\/p\u003e\u003cp\u003eInternal centrifugal pathways utilize a cast iron S-TUBE impeller designed to facilitate the passage of solids up to 110 mm without clogging. This specialized hydraulic design provides high efficiency and significant resistance to blockages, ensuring reliable wastewater transfer in intensive municipal service. By enabling particles to pass freely through the housing, the unit maintains volumetric throughput during prolonged service cycles. The S-TUBE impeller is specifically engineered for sewage handling where maintaining consistent flow is critical for system maintenance and network stability.\u003c\/p\u003e\u003cp\u003eMechanical construction consists of a cast iron pump housing with an IP68 protection rating for immersion up to 20 m deep and an ambient temperature range of -20°C to 40°C. Reliability is anchored by a double mechanical shaft seal featuring silicon carbide faces in an oil bath to protect the motor from liquid ingress. This model includes internal moisture sensors and thermistors for real-time monitoring of the Class H insulated motor assembly. Standardized DN 200 inlet and DN 200 outlet connections 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\u003eCast iron S-TUBE impeller provides 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 ensure structural durability for submerged duty up to 20 m deep.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with silicon carbide faces ensures the 11 kW motor remains shielded from liquid ingress.\u003c\/li\u003e\n\u003cli\u003eIntegrated thermistors and moisture sensors facilitate monitoring of the Class H insulated motor assembly.\u003c\/li\u003e\n\u003cli\u003eFour-pole motor operating at 1481 rpm provides the torque required for high-volume municipal wastewater transfer.\u003c\/li\u003e\n\u003cli\u003eDN 200 inlet and DN 200 outlet ports 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":50880857342199,"sku":"99776480","price":23426.44,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se1110200110452mn51dat-cast-iron-sewage-pump-for-sewage-transfer-with-s-tube-impeller.png?v=1782125104","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se1110200110452mn51dat-cast-iron-sewage-pump-for-sewage-transfer-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
