The SEV.80.100.13.4.50B addresses these requirements by providing a solution for wastewater and effluent transfer duties. This unit is intended for drainage stations where reliable solids passage and continuous operation are necessary for infrastructure maintenance. The system maintains stable performance in dry or submerged installations prone to varying fluid ingress and temperatures up to 40°C in subsurface pits.\u003c\/p\u003e\u003cp\u003eHydraulic capacity is provided by a 1.3 kW four-pole motor operating on a 415v three-phase supply with a rated current of 3.7 Amps. This assembly generates a maximum flow of 1098 L\/Min and achieves a maximum head of 8.4 m for pressurized sewer mains or gravity drainage. The motor operates at 1440 rpm, ensuring consistent pressure behavior and circulation characteristics during service cycles. Power is distributed through a 15-metre Lyniflex cable to support infrastructure in municipal wastewater networks and lift stations.\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 80 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 without internal clogging to maintain operational flow behavior in municipal collection pits.\u003c\/p\u003e\u003cp\u003eMechanical integrity is reinforced by a cast iron pump body and motor shell with an IP68 enclosure rating for protection against environmental contamination. Motor protection is anchored by a double mechanical shaft seal arrangement featuring a SiC\/SiC primary seal and CER\/CARNBR secondary seal in an oil bath. This unit includes an internal thermal sensor for motor monitoring and protection in submerged conditions. The casting includes a DN 80 inlet and DN 100 outlet connection for integration into standard wastewater infrastructure and treatment plants.\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 during wastewater handling.\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 1.3 kW motor.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure rating ensures the motor remains protected during permanent immersion in wastewater.\u003c\/li\u003e\n\u003cli\u003eDN 80 inlet and DN 100 outlet connections allow for wastewater transfer through standard industrial pipework.\u003c\/li\u003e\n\u003cli\u003eFour-pole motor configuration provides torque for processing wastewater in municipal collection systems.\u003c\/li\u003e\n\u003cli\u003eLyniflex 15-metre power cable provides a secure, oil-resistant connection for deep pit sewage pumping.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50874461782263,"sku":"96780762","price":7873.64,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-80-100-13-4-50b-cast-iron-4-pole-submersible-pump-for-grey-water-with-supervortex-impeller.png?v=1781859597","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-80-100-13-4-50b-cast-iron-4-pole-submersible-pump-for-grey-water-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
