Certified under CE EN12050-1, this cast iron model is intended for permanent installation in high-demand infrastructure. It is designed for untreated wastewater containing large solids in civil collection environments.\u003c\/p\u003e\u003cp\u003eA 4 kW 4-pole motor operating on a 3 x 415V supply with a rated current of 9.6 Amps powers the unit at 1464 rpm. It achieves a maximum flow up to 3816 L\/min and maximum head up to 11.7 m. The motor is calibrated 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 100 mm while helping reduce the risk of clogging. The hydraulic design features a DN 150 inlet and a 4\" (100 mm) outlet with DIN flange standards. This configuration supports consistent fluid handling in municipal wastewater networks.\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 integrated PTC sensors for motor protection. Integrated moisture sensors are used for seal and motor monitoring, along with 10 metres of LYNIFLEX power cable and an IP68 enclosure. 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 100 mm free passage for reliable transit of wastewater containing large solids.\u003c\/li\u003e\n\u003cli\u003e4 kW 4-pole motor operating at 1464 rpm on a 3 x 415V three-phase supply with 9.6 Amps rated current.\u003c\/li\u003e\n\u003cli\u003eDN 150 inlet and 4\" (100 mm) discharge connection for massive fluid trajectories in municipal networks.\u003c\/li\u003e\n\u003cli\u003eDouble mechanical SIC\/SIC shaft seals with an oil chamber for redundant moisture defence for the motor.\u003c\/li\u003e\n\u003cli\u003eIntegrated PTC sensors and moisture detection for advanced motor health and thermal monitoring.\u003c\/li\u003e\n\u003cli\u003eWinding-integrated thermal switches for automatic motor safety and overheating protection.\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 high-volume municipal wastewater transfer and collection systems.\u003c\/li\u003e\n\u003c\/ul\u003e\"","brand":"Grundfos","offers":[{"title":"Default Title","offer_id":50901322465527,"sku":"98625970","price":9767.01,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/grundfos-sl1-100-100-40-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-networks-with-s-tube-impeller.png?v=1782731405","url":"https:\/\/foundationpumps.com.au\/products\/grundfos-sl1-100-100-40-4-50b-c-cast-iron-4-pole-wastewater-pump-for-municipal-networks-with-s-tube-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
