This submersible pump is intended for the handling of contaminated liquids and grey water with a pH value between 4 and 10 in collection pits. The system addresses these environmental demands by providing reliable solids passage in liquids with temperatures up to 40°C. This unit maintains consistent performance in both dry and submerged installations where reliable wastewater transfer and effluent pumping are required for maintenance.\u003c\/p\u003e\u003cp\u003eHydraulic behavior is driven by a 3 kW motor operating on a 415v three-phase supply with a rated current of 6.3 Amps. This model achieves a maximum flow of 750 L\/Min and reaches a maximum head of 21.4 m to satisfy elevation requirements in pressurized sewer mains. The motor operates at 2910 rpm, maintaining torque and hydraulic stability during continuous duty cycles. Electrical connection is established via a 15-metre Lyniflex power cable, facilitating distribution for drainage stations and treatment plant transfer duties through an 80 mm outlet.\u003c\/p\u003e\u003cp\u003eInternal fluid paths utilize a SuperVortex impeller configuration designed for the free passage of solids up to 65 mm in diameter. This centrifugal configuration handles sewage and wastewater, preventing the internal clogging that could compromise volumetric throughput over long-term service. By utilizing a vortex flow path, the unit minimizes internal wear and vibration for the rotating assembly during prolonged discharge. The impeller is intended for grey water handling and wastewater transfer in municipal and industrial wastewater handling applications.\u003c\/p\u003e\u003cp\u003eMechanical construction features a cast iron housing and motor shell with an IP68 enclosure rating for protection against liquid ingress. Longevity is anchored by a double mechanical shaft seal arrangement with a SiC\/SiC primary seal and a CER\/CARNBR secondary seal in an oil bath. This unit includes a DN 80 inlet connection for integration into standard wastewater infrastructure and pump stations. The architectural casting features a stable base for firm positioning in deep subsurface pits and municipal collection systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSuperVortex impeller design handles solids up to 65 mm without risk of internal blockages during wastewater disposal.\u003c\/li\u003e\n\u003cli\u003eCast iron pump housing and motor shell provide a rigid foundation for dry or submerged pit installations.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal in an oil bath with silicon carbide faces ensures protection for the 3 kW motor.\u003c\/li\u003e\n\u003cli\u003eDN 80 inlet and DN 80 outlet connections are sized for wastewater transfer through standard plumbing networks.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure rating ensures the motor remains protected during permanent immersion in contaminated liquids.\u003c\/li\u003e\n\u003cli\u003eMaximum head performance of 21.4 m supports discharge in municipal sewage collection and lift stations.\u003c\/li\u003e\n\u003cli\u003eLyniflex 15-metre power cable provides a secure electrical connection for three-phase 415v wastewater service.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50874461356279,"sku":"96047293","price":5946.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-65-80-30-2-50b-cast-iron-2-pole-submersible-pump-for-effluent-transfer-with-supervortex-impeller.png?v=1781859573","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-65-80-30-2-50b-cast-iron-2-pole-submersible-pump-for-effluent-transfer-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
