This submersible pump is intended for the pumping of contaminated liquids in collection pits where a stable pH between 4 and 10 is maintained. The system addresses these environmental demands by providing a solution for wastewater and effluent containing organic solids. This unit supports wastewater transfer and pump station duties where solids passage and liquid temperature management up to 40°C are required.\u003c\/p\u003e\u003cp\u003eHydraulic capacity is provided by a 7.5 kW four-pole motor operating on a 415v three-phase supply with a rated current of 16.4 Amps. This model achieves a maximum flow of 2418 L\/Min and reaches a maximum head of 19.5 m to satisfy requirements in pressurized sewer mains and lift stations. The motor operates at 1455 rpm, maintaining torque and hydraulic stability throughout the service cycle in drainage stations. Electrical connection is established via a 15-metre Lyniflex power cable, facilitating distribution for sub-surface wastewater handling applications.\u003c\/p\u003e\u003cp\u003eInternal centrifugal design utilizes a SuperVortex impeller configuration to facilitate the passage of solids in suspension. This design handles particles up to 100 mm in diameter, preventing the internal clogging that could otherwise compromise volumetric efficiency over long-term service. By utilizing a vortex flow path, the unit minimizes internal friction and vibration to protect the rotating assembly during prolonged discharge. The impeller handles liquids containing organic materials to maintain operational flow behavior in wastewater collection pits and pump stations.\u003c\/p\u003e\u003cp\u003eMechanical stability is achieved through a heavy-duty cast iron body and motor shell with an IP68 protection rating for permanent dry or submerged installations. Longevity is anchored by a double mechanical shaft seal arrangement featuring a SiC\/SiC primary seal in an oil bath for motor insulation and durability. This unit includes integrated thermal sensors for motor monitoring and protection against overheating. The architectural casting features a DN 100 inlet and DN 100 outlet size for integration into standard wastewater infrastructure.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSuperVortex impeller configuration facilitates the passage of solids up to 100 mm without internal clogging.\u003c\/li\u003e\n\u003cli\u003eHeavy-duty cast iron housing and motor shell provide a durable foundation for dry and submerged site installations.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal in an oil bath with silicon carbide faces ensures protection for the 7.5 kW motor.\u003c\/li\u003e\n\u003cli\u003eMaximum head performance of 19.5 m allows for wastewater discharge in municipal and lift station applications.\u003c\/li\u003e\n\u003cli\u003eStandard 15-metre Lyniflex power cable provides a secure, oil-resistant connection for deep pit sewage pumping.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure rating ensures the motor remains protected during permanent immersion in contaminated liquids.\u003c\/li\u003e\n\u003cli\u003eDN 100 inlet and DN 100 outlet connections allow for high-volume wastewater transfer through standard pipework.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50874462175479,"sku":"96047411","price":15021.15,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-100-100-75-4-50b-cast-iron-4-pole-submersible-pump-for-drainage-with-supervortex-impeller.png?v=1781859627","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-100-100-75-4-50b-cast-iron-4-pole-submersible-pump-for-drainage-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
