The SE.150.100.4.52H.N.51D.A.T addresses these environmental demands by providing a solution for effluent transfer where fluid temperatures range between -10 and 40 degrees Celsius. This four-pole pump maintains stable performance in drainage stations and lift stations. The system is intended for permanent installation in subsurface collection pits prone to varying liquid ingress.\u003c\/p\u003e\u003cp\u003eHydraulic capacity is driven by a 10 kW four-pole motor operating on a 415v three-phase supply with a rated current of 21 Amps. This assembly generates a maximum flow of 6000 L\/Min and achieves a maximum head of 21.1 m for wastewater transfer. Operating at 1482 rpm, the motor provides the starting torque necessary for processing fluids in high-volume collection systems. Power is distributed through a 15-metre power cable to support integration into gravity drainage networks.\u003c\/p\u003e\u003cp\u003eInternal fluid paths feature an Open S-Tube centrifugal impeller designed for the free passage of solids in suspension. This configuration facilitates the movement of wastewater without the internal clogging that could otherwise compromise volumetric throughput over prolonged service. By utilizing a high-efficiency hydraulic profile, the unit minimizes internal friction and vibration to protect the rotating assembly during high-volume discharge. The Open S-Tube design is intended for municipal wastewater handling where reliable flow behavior is required.\u003c\/p\u003e\u003cp\u003eMechanical construction features a heavy-duty cast iron housing and motor shell with an IP68 enclosure rating for immersion up to 20 m. Motor insulation is maintained by a Class H assembly shielded by double mechanical shaft seals in an oil bath for maximum durability. Integrated moisture sensors and thermistors allow for proactive monitoring and early fault detection. The casting includes DN 150 inlet and DN 150 outlet connections for high-volume liquid transfer through standardized plumbing networks.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eFour-pole motor configuration operating at 1482 rpm provides the hydraulic torque needed for processing high-volume wastewater.\u003c\/li\u003e\n\u003cli\u003eOpen S-Tube impeller design enables the passage of solids through the pump casing without compromising hydraulic throughput.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron housing and motor shell provide a rigid structural foundation for installations up to 20 m deep.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal utilizing silicon carbide faces in an oil bath ensures the motor remains shielded from liquid ingress.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure rating confirms the unit is suitable for permanent immersion in wastewater environments up to 20 m deep.\u003c\/li\u003e\n\u003cli\u003eIntegrated thermistors and moisture sensors enable real-time monitoring to safeguard the Class H insulation assembly.\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\u003eIntegral cooling jacket supports operational integrity in both dry and submerged installation environments.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50877280977143,"sku":"99958946","price":17757.39,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se-150-100-4-52h-n-51d-a-t-cast-iron-4-pole-sewage-pump-for-municipal-wastewater-with-open-s-tube-impeller.png?v=1781949696","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se-150-100-4-52h-n-51d-a-t-cast-iron-4-pole-sewage-pump-for-municipal-wastewater-with-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
