This 6-pole cast iron assembly manages massive liquid movement in municipal networks while processing fluids within a liquid temperature range of 10°C to 40°C. For facilities requiring high-capacity drainage with minimal turbulence, this unit provides stable performance in permanent submerged or dry environments. Its robust construction is specifically intended for large-scale municipal complexes prone to high ingress.\u003c\/p\u003e\u003cp\u003eTechnical capacity is driven by an 11 kW six-pole motor operating on a 415v three-phase supply with a rated current of 26 Amps. This configuration generates a maximum flow of 16320 L\/min and achieves a maximum head of approximately 7.6 m to satisfy requirements in large collection complexes. The motor operates at a stable 983 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 pits across an ambient temperature range of -20 to 40°C.\u003c\/p\u003e\u003cp\u003eInternal hydraulics utilize a high-efficiency DUAL S-TUBE impeller designed to manage the passage of solids up to 125 mm without contact. This specialized configuration provides significant clog resistance and ensures reliable wastewater transfer, reducing the risk of downtime during intensive municipal service cycles. By enabling the free movement of large suspended particles through the housing, the unit maintains its volumetric efficiency throughout its operational life. This impeller setup is specifically engineered for high-volume municipal wastewater handling where system durability is critical.\u003c\/p\u003e\u003cp\u003eMechanical integrity is reinforced by a heavy-duty cast iron housing and an IP68 protection rating for depths up to 20 m. 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 integrated thermistors and moisture sensors for proactive monitoring of the Class H insulated motor assembly. Standardized DN 300 inlet and DN 300 outlet connections allow for standardized integration into municipal wastewater pipework and high-capacity drainage infrastructure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDUAL S-TUBE impeller design enables the passage of solids up to 125 mm with significant resistance to internal clogging.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron housing and motor shell provide the structural durability required for submerged installations.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal utilizing silicon carbide faces ensures the 11 kW motor remains shielded from liquid 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\u003eSix-pole motor configuration operating at 983 rpm provides the torque needed for high-volume effluent transfer.\u003c\/li\u003e\n\u003cli\u003eDN 300 inlet and DN 300 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 submerged environments.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50880861667575,"sku":"99776971","price":32105.65,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se2125300110652en51dat-cast-iron-sewage-pump-for-civil-drainage-with-dual-s-tube-impeller.png?v=1782125132","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se2125300110652en51dat-cast-iron-sewage-pump-for-civil-drainage-with-dual-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
