The pump is suitable for permanent submerged installation in wet wells and basins where untreated wastewater containing solids must be handled.\u003c\/p\u003e\u003cp\u003eThe pump is powered by a 3 kW 2-pole motor with a rated speed of 2909 rpm. Operating on a 3 x 415V supply with a rated current of 6.4 Amps, it achieves a maximum head up to 22 m and a maximum flow up to 1164 L\/min. It is rated for continuous S1 submerged duty in 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 a 50 mm free passage for untreated wastewater containing solids while helping reduce the risk of clogging. Connection sizes include a DN 65 inlet and a DN 65 (2.5\") outlet with DIN flanges. The single-vane hydraulic design facilitates the conveying of raw effluents through discharge piping.\u003c\/p\u003e\u003cp\u003eConstruction includes an EN-GJL-250 cast iron pump housing and motor casing with double SIC\/SIC mechanical shaft seals. Integrated moisture and water-in-oil sensors are used for seal and motor monitoring. Winding-embedded thermal switches protect the stator, and the unit includes 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\u003eExplosion-proof EX certified motor housing for safe operation in hazardous environments and explosive atmospheres.\u003c\/li\u003e\n\u003cli\u003eS-tube impeller with 50 mm free passage for pumping untreated wastewater containing solids without clogging.\u003c\/li\u003e\n\u003cli\u003e3 kW 2-pole motor operating at 2909 rpm on a 3 x 415V three-phase supply with 6.4 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eHigh-head performance up to 22 m for demanding wastewater transfer applications in municipal infrastructure.\u003c\/li\u003e\n\u003cli\u003eDN 65 inlet and DN 65 (2.5\") discharge connection with DIN flanges for standard municipal piping systems.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC seals in an oil chamber providing redundant shaft protection against moisture ingress.\u003c\/li\u003e\n\u003cli\u003eIntegrated water-in-oil and moisture sensors for promonitoring of seal and motor integrity.\u003c\/li\u003e\n\u003cli\u003e10-metre heavy-duty LYNIFLEX power cable and IP68 enclosure for reliable submerged service in deep sumps.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901320892663,"sku":"98626554","price":6037.64,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-50-65-30-a-ex-2-50b-c-cast-iron-2-pole-wastewater-pump-for-high-head-transfer-with-s-tube-impeller.png?v=1782731362","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-50-65-30-a-ex-2-50b-c-cast-iron-2-pole-wastewater-pump-for-high-head-transfer-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
