This submersible pump addresses the requirements of municipal wastewater networks and sewage collection systems where grey water with a pH range of 4 to 10 is present. The unit is intended for wastewater transfer and effluent management in collection pits. It maintains stable operation in dry or submerged installations prone to varying fluid ingress and temperatures up to 40°C to support sub-surface infrastructure and pump stations.\u003c\/p\u003e\u003cp\u003eHydraulic performance is driven by a 4 kW motor on a 415v three-phase supply, generating a maximum flow of 1002 L\/Min. This model achieves a maximum total head of 29.6 m, making it suitable for discharge in pressurized sewer mains and treatment plant transfer duties. Operating with a rated current of 8.2 Amps at 2925 rpm, the unit maintains consistent torque for processing fluids in drainage stations. Rapid evacuation is achieved through the DN 65 discharge port using a 10-metre power cable for secure electrical distribution.\u003c\/p\u003e\u003cp\u003eInternal centrifugal design utilizes a SuperVortex impeller to facilitate the passage of solids up to 65 mm in diameter without internal clogging. This configuration handles wastewater in suspension, maintaining volumetric efficiency throughout prolonged service cycles. By utilizing a vortex flow path, the unit minimizes internal vibration and friction to protect the rotating assembly during grey water handling. The impeller configuration is intended for liquids containing soft solids and organic materials in municipal and industrial wastewater handling.\u003c\/p\u003e\u003cp\u003eMechanical stability is achieved through a heavy-duty cast iron housing and motor shell with an IP68 protection rating for permanent dry or submerged installations. The motor is shielded by a double mechanical shaft seal in an oil bath, utilizing a SiC\/SiC primary seal for abrasive resistance and a CER\/CARNBR secondary seal. This A-version model features an Ex-rated motor with integrated moisture and water-in-oil sensors for fault detection. The assembly includes a DN 80 inlet for integration into wastewater 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 transfer.\u003c\/li\u003e\n\u003cli\u003eCast iron pump housing and motor shell provide a stable foundation for dry or submerged pit installations up to 20 m deep.\u003c\/li\u003e\n\u003cli\u003eMaximum head performance of 29.6 m allows for wastewater discharge in municipal and treatment plant applications.\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\u003eEx-rated explosion protection standard enables deployment in hazardous zones according to IEC 60079-15 requirements.\u003c\/li\u003e\n\u003cli\u003eIntegrated moisture and water-in-oil sensors facilitate proactive monitoring and detection of seal ingress.\u003c\/li\u003e\n\u003cli\u003eLyniflex 10-metre power cable provides a secure, chemical-resistant electrical connection for wastewater handling service.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50874461225207,"sku":"92871090","price":7239.95,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-65-65-40-a-ex-2-50b-cast-iron-ex-rated-submersible-pump-for-grey-water-with-supervortex-impeller.png?v=1781859569","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-65-65-40-a-ex-2-50b-cast-iron-ex-rated-submersible-pump-for-grey-water-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
