The SEV.80.100.40.4.50B addresses these requirements by providing a solution for wastewater and effluent transfer duties in subsurface pits. 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.\u003c\/p\u003e\u003cp\u003eHydraulic capacity is provided by a 4 kW four-pole motor operating on a 415v three-phase supply with a rated current of 9.6 Amps. This assembly generates a maximum flow of 1500 L\/Min and achieves a maximum head of 16.5 m for gravity drainage and lift station applications. The motor operates at a synchronous speed of 1460 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 networks and treatment plant transfer duties.\u003c\/p\u003e\u003cp\u003eInternal centrifugal design utilizes a SuperVortex impeller configuration to facilitate the passage of solids up to 80 mm in diameter. This design handles wastewater in suspension, preventing the internal clogging that could otherwise compromise volumetric efficiency over long-term service. By utilizing the vortex principle, 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 heavy-duty cast iron housing and motor shell with an IP68 enclosure rating for protection against environmental ingress. 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 model includes an internal thermal sensor for motor monitoring and protection in aggressive submerged environments. The casting 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 4 kW motor.\u003c\/li\u003e\n\u003cli\u003eFour-pole motor configuration operating at 1460 rpm provides torque for processing wastewater in municipal networks.\u003c\/li\u003e\n\u003cli\u003eStandard 15-metre Lyniflex power cable provides a secure, oil-resistant connection for sewage pumping applications.\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 plumbing.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50874461913335,"sku":"96780759","price":10252.28,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-80-100-40-4-50b-cast-iron-4-pole-submersible-pump-for-sewage-collection-with-supervortex-impeller.png?v=1781859606","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-80-100-40-4-50b-cast-iron-4-pole-submersible-pump-for-sewage-collection-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
