The SEV.100.100.30.4.50B addresses these operational requirements by handling grey water and effluent where reliable solids passage is necessary. This unit supports service in drainage stations and lift stations, maintaining stable performance in dry or submerged installations with liquid temperatures from 0 to 40°C. Installation is possible in subsurface collection pits prone to varying liquid levels and environmental service demands.\u003c\/p\u003e\u003cp\u003eHydraulic behavior is defined by a 3 kW four-pole motor operating on a 415v three-phase supply with a rated current of 7.4 Amps. This assembly generates a maximum flow of 1914 L\/Min and reaches a maximum head of 11.3 m to satisfy specific site discharge requirements. The model operates at a synchronous speed of 1455 rpm, ensuring consistent pressure behavior and circulation characteristics during the pumping cycle. Power is distributed through a 15-metre Lyniflex cable to support infrastructure in gravity drainage networks and pump stations.\u003c\/p\u003e\u003cp\u003eInternal fluid paths utilize a SuperVortex impeller configuration to facilitate the passage of solids in suspension. This centrifugal design allows for the free movement of particles up to 100 mm in diameter, preventing internal contact that could compromise volumetric efficiency over long-term service. By utilizing a vortex flow path, the unit minimizes internal friction and vibration to protect the rotating assembly during prolonged wastewater handling. The impeller handles liquids containing organic materials without internal clogging to maintain operational flow behavior in municipal collection pits.\u003c\/p\u003e\u003cp\u003eMechanical construction features a cast iron pump housing and motor shell with an IP68 enclosure rating for protection against liquid ingress. The motor is shielded by a SiC\/SiC primary shaft seal and a CER\/CARNBR secondary seal in an oil bath for insulation and durability. This unit includes an internal thermal sensor for motor protection and is intended for wastewater handling where reliable transfer is required for infrastructure maintenance. The casting includes a DN 100 inlet and a 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 design facilitates the passage of solids up to 100 mm through the pump casing to maintain hydraulic throughput.\u003c\/li\u003e\n\u003cli\u003eCast iron pump housing and motor shell provide the structural rigidity required for dry or submerged installation depths up to 20 m.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical shaft seal arrangement with silicon carbide and ceramic\/carbon faces in an oil bath ensures motor protection.\u003c\/li\u003e\n\u003cli\u003eIP68 enclosure rating confirms the unit is suitable for permanent immersion in wastewater with a pH range of 4 to 10.\u003c\/li\u003e\n\u003cli\u003eDN 100 inlet and DN 100 outlet ports are sized for standard connection to wastewater collection pits and infrastructure.\u003c\/li\u003e\n\u003cli\u003eLyniflex 15-metre power cable provides a secure electrical connection to three-phase 415v supplies in wastewater environments.\u003c\/li\u003e\n\u003cli\u003eFour-pole motor configuration operating at 1455 rpm provides torque for processing wastewater in municipal networks.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50874462077175,"sku":"96047443","price":9838.83,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sev-100-100-30-4-50b-cast-iron-4-pole-submersible-pump-for-sewage-collection-with-supervortex-impeller.png?v=1781859622","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sev-100-100-30-4-50b-cast-iron-4-pole-submersible-pump-for-sewage-collection-with-supervortex-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
