This submersible wastewater pump is intended for sewage collection systems and municipal networks processing grey water with a pH between 4 and 10. The system handles contaminated liquids in both dry and submerged installation environments where liquid temperatures are managed between 0 and 40°C. This unit supports wastewater transfer and effluent pumping where reliable solids passage and hydraulic stability are necessary for infrastructure maintenance.\u003c\/p\u003e\u003cp\u003eHydraulic capacity is provided by a 3 kW motor operating on a 415v three-phase supply with a rated current of 6.6 Amps. This model achieves a maximum flow of 750 L\/Min and reaches a maximum head of 21.6 m to satisfy requirements in pressurized sewer mains. The motor operates at 2910 rpm, maintaining torque and circulation characteristics throughout the service cycle in drainage stations. Electrical connection is established via a 10-metre Lyniflex power cable, facilitating distribution for sub-surface wastewater handling and pump stations.\u003c\/p\u003e\u003cp\u003eInternal fluid paths feature a SuperVortex centrifugal impeller designed for the free passage of solids up to 65 mm in diameter. This configuration handles sewage and wastewater, maintaining volumetric throughput and preventing the internal clogging that could compromise the rotating assembly. By creating a vortex flow within the pump housing, the design reduces internal wear and vibration during continuous operation. The hydraulic setup facilitates the movement of contaminated fluids and effluent through drainage stations and municipal lift stations.\u003c\/p\u003e\u003cp\u003eMechanical stability is reinforced by an IP68 enclosure rating and a double mechanical shaft seal arrangement. The primary SiC\/SiC seal and secondary CER\/CARNBR seal in an oil bath protect the electrical heart from liquid ingress in submerged conditions. This A-version model utilizes integrated moisture and water-in-oil sensors for early fault detection. The architectural casting includes a DN 80 inlet and a DN 65 outlet, ensuring structural integrity for permanent wastewater infrastructure and treatment plant transfer duties in hazardous areas.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSuperVortex impeller configuration allows for the passage of solids up to 65 mm, reducing the risk of internal clogs in wastewater.\u003c\/li\u003e\n\u003cli\u003eCast iron pump housing and motor shell provide structural durability for permanent dry or submerged deployment in wastewater pits.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal with silicon carbide and ceramic\/carbon faces ensures motor protection in an oil bath.\u003c\/li\u003e\n\u003cli\u003eIntegrated water-in-oil and moisture sensors enable real-time monitoring to facilitate fault detection during service.\u003c\/li\u003e\n\u003cli\u003eEx-rated motor standard complies with IEC 60079-15 for safe operation in hazardous municipal and industrial environments.\u003c\/li\u003e\n\u003cli\u003eSynchronous speed of 2910 rpm provides fluid discharge for pressurized sewage mains and gravity drainage.\u003c\/li\u003e\n\u003cli\u003eLyniflex 10-metre oil-resistant power cable ensures a secure connection to the 415v three-phase power supply in contaminated liquids.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50874461192439,"sku":"92871089","price":6550.61,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-65-65-30-a-ex-2-50d-cast-iron-ex-rated-submersible-pump-for-sewage-with-supervortex-impeller.png?v=1781859567","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-65-65-30-a-ex-2-50d-cast-iron-ex-rated-submersible-pump-for-sewage-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
