The Grundfos SE1.85.100.130.4.52H.N.51D.A.T Submersible Wastewater Pump provides a professional solution for collection pits and drainage stations. This unit operates within a temperature range of 10 to 40°C, ensuring reliable performance in municipal networks and industrial transfer duties. The cast iron construction is intended for high-volume sewage handling across intensive service cycles.\u003c\/p\u003e\u003cp\u003eTechnical capacity is driven by a 13 kW four-pole motor on a 415v three-phase supply, generating a maximum head of 23 m and a maximum flow of 4986 L\/min. Operating with a rated current of 25 Amps at 1483 rpm, the pump maintains stable pressure for high-load evacuation duties. A star-delta starting method is utilized to manage peak electrical loads and ensure consistent torque during activation. Power is distributed through a 15-metre S1BN8-F power cable to support integration into deep-pit wastewater handling infrastructure and municipal lift stations.\u003c\/p\u003e\u003cp\u003eInternal fluid pathways utilize an S-TUBE impeller configuration to facilitate the passage of solids up to 85 mm without internal clogging. This hydraulic design ensures high efficiency and reliable wastewater transfer, reducing the risk of internal blockages during continuous duty in municipal networks. The S-TUBE impeller is engineered for durability, maintaining volumetric efficiency throughout thousands of operating hours in aggressive fluids. This configuration is specifically intended for grey water and sewage handling where system reliability is critical for infrastructure protection.\u003c\/p\u003e\u003cp\u003eMechanical construction features a heavy-duty cast iron body and motor shell with an IP68 protection rating for depths up to 20 m. Reliability is supported by a double mechanical shaft seal with silicon carbide faces in an oil bath to protect the motor from ingress. This model includes integrated thermistors and moisture sensors for proactive monitoring of the Class H insulated motor assembly. Standard DN 150 inlet and DN 100 outlet connections allow for standardized integration into municipal wastewater and civil drainage pipework.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eS-TUBE impeller design enables the passage of solids up to 85 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 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\u003eFour-pole 13 kW motor configuration operating at 1483 rpm provides the torque needed for municipal sewage transfer.\u003c\/li\u003e\n\u003cli\u003eStandardized DN 150 inlet and DN 100 outlet connections allow for seamless integration into municipal pipework.\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":50880852623607,"sku":"99776096","price":19205.26,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-se185100130452hn51dat-cast-iron-sewage-pump-for-effluent-handling-with-s-tube-impeller.png?v=1782125070","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-se185100130452hn51dat-cast-iron-sewage-pump-for-effluent-handling-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
