This model is suitable for permanent installation in collection reservoirs and sumps for handling untreated wastewater.\u003c\/p\u003e\u003cp\u003eThe model features a 4 kW 2-pole motor running at 2930 rpm. Operating on a 3 x 415V supply with a rated current of 8.2 Amps, it provides a maximum head up to 25.8 m and a maximum flow up to 1164 L\/min. The motor is rated for continuous S1 duty in untreated wastewater at temperatures between 0°C and 40°C. The motor is cooled by the surrounding pumped liquid during normal submerged operation.\u003c\/p\u003e\u003cp\u003eThe S-tube impeller is designed for untreated wastewater containing solids up to 50 mm while helping reduce the risk of clogging. It utilises a DN 65 inlet and a DN 65 (2.5\") outlet with DIN flange standards. This design supports the transfer of solids through high-resistance discharge piping in industrial facilities.\u003c\/p\u003e\u003cp\u003eThe pump housing and motor casing are constructed from EN-GJL-250 cast iron. Protection includes a double SIC\/SIC mechanical seal and integrated PTC sensors for motor protection. Integrated moisture and water-in-oil sensors are used for seal and motor monitoring, and the unit features a 10-metre 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\u003eExplosion-proof EX certified construction for safe deployment in hazardous processing zones and industrial environments.\u003c\/li\u003e\n\u003cli\u003eS-tube impeller with 50 mm free passage for reliable processing of wastewater with high solids content.\u003c\/li\u003e\n\u003cli\u003e4 kW 2-pole motor operating at 2930 rpm on a 3 x 415V three-phase supply with 8.2 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eHigh-head performance up to 25.8 m for high-pressure wastewater relocation in industrial facilities.\u003c\/li\u003e\n\u003cli\u003eDN 65 inlet and DN 65 (2.5\") discharge connection with DIN flange standards for industrial piping systems.\u003c\/li\u003e\n\u003cli\u003eDouble SIC\/SIC mechanical shaft seals with oil chamber providing redundant protection for the motor and shaft.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTC sensors and moisture detection for advanced motor health and seal monitoring.\u003c\/li\u003e\n\u003cli\u003e10-metre rugged LYNIFLEX power cable and IP68 enclosure for continuous submerged operation in industrial sumps.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901320990967,"sku":"98626551","price":6699.91,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-50-65-40-a-ex-2-50b-c-cast-iron-2-pole-wastewater-pump-for-industrial-effluent-with-s-tube-impeller.png?v=1782731365","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-50-65-40-a-ex-2-50b-c-cast-iron-2-pole-wastewater-pump-for-industrial-effluent-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
