It is intended for permanent installation in wet wells and is designed for handling untreated wastewater containing large solids in municipal and industrial infrastructure.\u003c\/p\u003e\u003cp\u003ePerformance is driven by a 2.2 kW 4-pole motor drawing 5.4 Amps at 415V while operating at 1462 rpm. It achieves a maximum flow up to 2214 L\/min and a maximum head up to 11.3 m. The motor is rated for continuous S1 duty in untreated wastewater with a temperature range of 0°C 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. It features a DN 100 inlet and a DN 80 (3\") outlet with DIN flange standards. This single-vane hydraulic path supports the transfer of solids during prolonged dewatering in treatment plants.\u003c\/p\u003e\u003cp\u003eConstruction consists of an EN-GJL-250 cast iron pump housing and motor casing. Shaft protection is provided by a double SIC\/SIC mechanical seal system and winding-integrated thermal switches. The unit also includes moisture sensors, a 10-metre 07RN8-F power cable, and an IP68 enclosure rating for submerged operation. 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 in treatment plant sumps.\u003c\/li\u003e\n\u003cli\u003e2.2 kW 4-pole motor operating at 1462 rpm on a 3 x 415V three-phase supply with 5.4 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eDN 100 inlet and DN 80 (3\") discharge connection for efficient fluid relocation in treatment plants.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC shaft seals with an oil chamber providing redundant moisture defence for the stator.\u003c\/li\u003e\n\u003cli\u003eIntegrated moisture sensors for monitoring of internal mechanical components during deep submersion.\u003c\/li\u003e\n\u003cli\u003eWinding-embedded thermal switches for automatic electrical safety and protection against overheating.\u003c\/li\u003e\n\u003cli\u003e10-metre 07RN8-F power cable and IP68 moisture protection for reliable submerged operation in deep basins.\u003c\/li\u003e\n\u003cli\u003eCE EN12050-1 certified for use in wastewater treatment plants and large-scale utility infrastructure.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901321613559,"sku":"98626024","price":5907.16,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-80-80-22-4-50b-c-cast-iron-4-pole-wastewater-pump-for-treatment-plants-with-s-tube-impeller.png?v=1782731377","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-80-80-22-4-50b-c-cast-iron-4-pole-wastewater-pump-for-treatment-plants-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
