This unit holds CE EN12050-1 approval and is intended for handling untreated wastewater containing large solids. It is designed for high-flow fluid transfer in municipal networks.\u003c\/p\u003e\u003cp\u003eThis model features a 5.5 kW 4-pole motor operating at 1463 rpm. Operating on a 3 x 415V supply with a rated current of 10.9 Amps, it achieves a maximum flow up to 3282 L\/min and a maximum head up to 19.4 m. The motor is rated for continuous S1 duty in untreated wastewater at temperatures up to 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.\u003c\/p\u003e\u003cp\u003eThe S-tube impeller provides an 80 mm free passage for untreated wastewater containing solids while helping reduce the risk of clogging. The unit is equipped with a DN 100 inlet and a DN 80 (3\") outlet connection. This single-vane hydraulic configuration supports the discharge of raw effluents in municipal collection sumps.\u003c\/p\u003e\u003cp\u003eThe pump housing and motor casing are constructed from EN-GJL-250 cast iron for durability in submerged service. Protection includes a double mechanical SIC\/SIC seal arrangement and integrated PTC sensors for motor monitoring. Integrated moisture sensors are included for seal and motor monitoring, along with a 10-metre LYNIFLEX cable and IP68 rating. The pump is suitable for installation depths up to 7 metres.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eS-tube impeller with 80 mm free passage for processing wastewater with high solids content without clogging.\u003c\/li\u003e\n\u003cli\u003e5.5 kW 4-pole motor operating at 1463 rpm on a 3 x 415V three-phase supply with 10.9 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eDN 100 inlet and DN 80 (3\") discharge connection for high-volume municipal wastewater relocation.\u003c\/li\u003e\n\u003cli\u003eDouble SIC\/SIC mechanical seal arrangement with an oil chamber for redundant motor shaft protection.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTC sensors and moisture detection for advanced motor and seal health monitoring.\u003c\/li\u003e\n\u003cli\u003eWater-in-oil sensor included to provide early warning of potential fluid ingress into the internal oil chamber.\u003c\/li\u003e\n\u003cli\u003e10-metre rugged LYNIFLEX power cable and IP68 protection classification for deep-well operation.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in high-capacity municipal transfer and collection systems.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901321908471,"sku":"98626061","price":10147.56,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-80-80-55-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-transfer-with-s-tube-impeller.png?v=1782731384","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-80-80-55-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-transfer-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
