This explosion-proof model holds CE EN12050-2 and IECEX certifications for use in hazardous environments. It is intended for permanent submerged installation in wet wells using an auto-coupling system or for wastewater transfer in municipal networks.\u003c\/p\u003e\u003cp\u003eA 2.2 kW 2-pole motor powers the unit at 2900 rpm on a 3 x 415V supply with a rated current of 4.7 Amps. It achieves a maximum head up to 17.7 m and a maximum flow up to 1248 L\/min. The motor is designed 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 hydraulic design utilises an S-tube impeller providing a 50 mm free passage for untreated wastewater containing solids while helping reduce the risk of clogging. The unit is equipped with a DN 65 inlet and a DN 65 (2.5\") outlet connection with DIN flange standards. This configuration supports consistent fluid discharge in civil wastewater systems.\u003c\/p\u003e\u003cp\u003eBuilt with an EN-GJL-250 cast iron pump housing and motor casing, the unit includes a double SIC\/SIC mechanical shaft seal arrangement. Integrated moisture and water-in-oil sensors are used for seal and motor monitoring. Protection includes winding-embedded thermal switches, 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 suitable for operation in hazardous municipal utility environments.\u003c\/li\u003e\n\u003cli\u003eS-tube impeller providing a 50 mm free passage for reliable transit of wastewater containing solids.\u003c\/li\u003e\n\u003cli\u003e2.2 kW 2-pole motor operating at 2900 rpm on a 3 x 415V three-phase supply with 4.7 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eDN 65 inlet and DN 65 (2.5\") discharge connection with DIN flange standards for municipal infrastructure.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC shaft seals with an oil chamber providing redundant protection against moisture ingress.\u003c\/li\u003e\n\u003cli\u003eIntegrated moisture and water-in-oil sensors for monitoring of seal integrity and motor protection.\u003c\/li\u003e\n\u003cli\u003eWinding-embedded thermal switches for automatic electrical safety and overheating protection.\u003c\/li\u003e\n\u003cli\u003e10-metre LYNIFLEX power cable and IP68 enclosure rating for continuous submerged wet well service.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901320827127,"sku":"98626553","price":5470.11,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-50-65-22-a-ex-2-50b-c-cast-iron-2-pole-wastewater-pump-for-municipal-networks-with-s-tube-impeller.png?v=1782731358","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-50-65-22-a-ex-2-50b-c-cast-iron-2-pole-wastewater-pump-for-municipal-networks-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
