The Grundfos SE.100.150.2.52S.N.51D.A.T addresses environmental demands by providing a solution for effluent transfer where fluid temperatures range between -10 and 40 degrees Celsius. Designed for deployment in drainage stations and collection pits, the assembly supports continuous service for infrastructure protection. The heavy-duty housing is intended for wastewater pumping in subsurface civil works.\u003c\/p\u003e\u003cp\u003eHydraulic performance is provided by a 15 kW motor on a 415v three-phase supply, generating a maximum flow of 4314 L\/Min and a maximum head of 39.2 m. Operating with a rated current of 29 Amps at 2966 rpm, the unit maintains consistent torque and hydraulic stability during high-load evacuation cycles. A star-delta starting method is utilized to optimize electrical consumption and manage start-up loads in deep-pit applications. Electrical distribution is established via a 15-metre power cable to facilitate deployment in subsurface networks.\u003c\/p\u003e\u003cp\u003eInternal fluid velocity paths feature a high-efficiency Open S-Tube impeller designed for the movement of solids in suspension without internal clogging. This centrifugal setup facilitates the free passage of particles through the housing, preventing the contact that could compromise volumetric throughput during prolonged service. By utilizing the Open S-Tube principle, the unit reduces internal wear and vibration for the rotating assembly during high-head discharge. The hydraulic configuration is intended for high-volume wastewater handling.\u003c\/p\u003e\u003cp\u003eMechanical integrity is reinforced by a cast iron pump body and motor shell with an IP68 protection rating for depths up to 20 m. Longevity is anchored by a Class H motor assembly shielded by a double mechanical shaft seal arrangement in an oil bath for maximum insulation. This model includes integrated moisture sensors and thermistors for proactive monitoring and early fault detection in submerged conditions. The architectural casting features a 299 kg net weight and DN 100 ports for integration into standardized municipal infrastructure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOpen S-Tube impeller configuration facilitates high-efficiency liquid handling and prevents internal blockages in municipal networks.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron housing and motor shell provide the structural durability needed for permanent submerged installations up to 20 m deep.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal featuring silicon carbide faces in an oil bath ensures the 15 kW motor remains shielded.\u003c\/li\u003e\n\u003cli\u003eIP68 protection rating confirms the unit is suitable for continuous duty in submerged 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 insulated motor assembly.\u003c\/li\u003e\n\u003cli\u003eTwo-pole motor operating at 2966 rpm provides the high-velocity discharge required for wastewater collection systems.\u003c\/li\u003e\n\u003cli\u003eStandardized DN 100 inlet and DN 100 outlet connections allow for seamless integration into municipal wastewater 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":50877280420087,"sku":"99965281","price":16900.28,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se-100-150-2-52s-n-51d-a-t-cast-iron-2-pole-sewage-pump-for-sewage-with-open-s-tube-impeller.png?v=1781949663","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se-100-150-2-52s-n-51d-a-t-cast-iron-2-pole-sewage-pump-for-sewage-with-open-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
