It is suitable for permanent submerged installation and developed for handling untreated wastewater containing large solids in civil infrastructure.\u003c\/p\u003e\u003cp\u003eThe pump is powered by a 7.5 kW 4-pole motor operating at 1462 rpm on a 3 x 415V supply with a rated current of 14.4 Amps. It achieves a maximum flow up to 3300 L\/min and a maximum head up to 23.6 m. The motor is designed for continuous S1 duty in untreated wastewater containing solids between 0°C and 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.\u003c\/p\u003e\u003cp\u003eFluid handling is managed by an S-tube impeller providing an 80 mm free passage while helping reduce the risk of clogging. Hydraulic connections include a DN 100 inlet and a DN 80 (3\") outlet with DIN flanges. This design facilitates the transfer of large suspended solids in demanding civil wastewater networks.\u003c\/p\u003e\u003cp\u003eConstruction features an EN-GJL-250 cast iron pump housing and motor casing. Protection includes a double SIC\/SIC mechanical shaft seal and integrated PTC thermal sensors for motor protection. The unit features moisture sensors for seal and motor monitoring, 10 metres of LYNIFLEX power cable, and an IP68 enclosure 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 reliable transit of large solids-laden wastewater in municipal networks.\u003c\/li\u003e\n\u003cli\u003e7.5 kW 4-pole motor operating at 1462 rpm on a 3 x 415V three-phase supply with 14.4 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eDN 100 inlet and DN 80 (3\") discharge connection for high-volume extraction in municipal networks.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC seals in an oil chamber providing a redundant moisture defence for the motor.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTC sensors and moisture detection for advanced motor health and active thermal monitoring.\u003c\/li\u003e\n\u003cli\u003eBuilt-in water-in-oil sensor for proactive early warning of moisture ingress into the internal oil chamber.\u003c\/li\u003e\n\u003cli\u003e10-metre rugged LYNIFLEX power cable and IP68 moisture protection for deep submerged service.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in demanding municipal wastewater transfer and collection networks.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901321974007,"sku":"98625985","price":11567.82,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-80-80-75-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-transfer-with-s-tube-impeller.png?v=1782731386","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-80-80-75-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-transfer-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
