This submersible unit addresses requirements for the removal of contaminated liquids with a pH value between 4 and 10. The pump is intended for drainage stations and wastewater transfer duties where reliable solids passage and continuous operation are **required** for 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 2.2 kW four-pole motor operating on a 415v three-phase supply with a rated current of 5.6 Amps. This assembly generates a maximum flow of 1398 L\/Min and achieves a maximum head of 12.4 m to satisfy discharge requirements in municipal lift stations. The motor operates at 1445 rpm, ensuring consistent pressure behavior and circulation characteristics during the service cycle. Power is distributed through a 15-metre Lyniflex cable to support sub-surface wastewater handling and gravity drainage networks.\u003c\/p\u003e\u003cp\u003eInternal fluid velocity paths utilize a SuperVortex impeller configuration to facilitate the passage of solids in suspension. This centrifugal design handles particles up to 80 mm in diameter, preventing internal clogging that could compromise volumetric efficiency over thousand of hours of operation. By utilizing a vortex flow path, the unit minimizes internal friction and vibration to protect the rotating assembly during prolonged service. The impeller handles liquids containing organic materials to maintain operational flow behavior in wastewater 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 permanent dry or submerged installations. Motor protection is anchored by a double mechanical shaft seal in an oil bath featuring a SiC\/SiC primary seal and CER\/CARNBR secondary seal. This unit includes an integrated thermal sensor for operational monitoring and protection against electrical fluctuations. The architectural casting features a DN 80 inlet and DN 80 outlet 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.\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 2.2 kW motor.\u003c\/li\u003e\n\u003cli\u003eFour-pole motor operating at 1445 rpm provides torque for processing wastewater containing dense organic materials.\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 wastewater.\u003c\/li\u003e\n\u003cli\u003eDN 80 inlet and DN 80 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":50874461520119,"sku":"96047497","price":7946.94,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-80-80-22-4-50b-cast-iron-4-pole-submersible-pump-for-sewage-collection-with-supervortex-impeller.png?v=1781859582","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-80-80-22-4-50b-cast-iron-4-pole-submersible-pump-for-sewage-collection-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
