This submersible pump addresses the requirements of municipal wastewater networks and sewage collection systems where contaminated liquids are present. The unit is intended for wastewater transfer and effluent management with a pH range of 4 to 10. It maintains stable operation in dry or submerged installations prone to varying fluid ingress and temperatures up to 40°C to support sub-surface infrastructure and pump stations.\u003c\/p\u003e\u003cp\u003eHydraulic capacity is provided by a 7.5 kW motor operating on a 415v three-phase supply with a rated current of 15 Amps. This high-capacity model achieves a maximum flow of 1836 L\/Min and reaches a maximum total head of 31.6 m for discharge in pressurized sewer mains. Operating at 2940 rpm, the unit maintains consistent 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 wastewater collection pits and lift stations.\u003c\/p\u003e\u003cp\u003eInternal centrifugal design utilizes a SuperVortex impeller to facilitate the passage of solids in suspension without internal clogging. This configuration handles particles up to 80 mm in diameter, maintaining volumetric efficiency throughout prolonged service cycles in municipal and industrial environments. By utilizing a vortex flow path, the unit minimizes internal vibration and friction to protect the rotating assembly during grey water handling. The impeller configuration is intended for liquids containing organic materials in municipal wastewater handling.\u003c\/p\u003e\u003cp\u003eMechanical stability is achieved through a heavy-duty cast iron housing and motor shell with an IP68 protection rating for permanent immersion. The motor is shielded by a double mechanical shaft seal in an oil bath, utilizing a SiC\/SiC primary seal and CER\/CARNBR secondary seal for durability and insulation. This unit features an internal thermal sensor for motor protection and monitoring during continuous operation. The assembly includes a DN 80 inlet and DN 100 outlet connection 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 80 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 31.6 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 systems.\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 80 inlet and DN 100 outlet connections allow for high-volume wastewater transfer through standard plumbing.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50874461978871,"sku":"96780756","price":14654.26,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-80-100-75-2-50b-cast-iron-2-pole-submersible-pump-for-lift-stations-with-supervortex-impeller.png?v=1781859609","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-80-100-75-2-50b-cast-iron-2-pole-submersible-pump-for-lift-stations-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
