This medium-head drainage pump is engineered to handle liquids with high sediment and grit concentrations without the risk of hydraulic blockage. It provides a robust and dependable solution for civil infrastructure sites and industrial facility managers needing rapid site dewatering in high-wear conditions.\u003c\/p\u003e \u003cp\u003eHydraulic delivery is driven by a 5.6 kW three-phase motor producing a maximum head of 27 m and a maximum flow rate of 2640 L\/Min. Operating at 415v with a rated current of 10 Amps, the induction motor provides the high torque needed for handling contaminated media. The squirrel cage motor is built for continuous duty and can support automated pumping cycles with up to 30 starts per hour in demand-driven systems.\u003c\/p\u003e \u003cp\u003eAt the heart of the pump is a specialized Hard-Iron® open impeller designed specifically for non-clogging performance in high-wear environments. This configuration works with a specialized suction cover to maintain hydraulic performance and resist the abrasive effects of site water. By ejecting debris from the hydraulic path during rotation, the pump ensures that efficiency remains high and energy consumption is minimized during prolonged dewatering cycles.\u003c\/p\u003e \u003cp\u003eConstruction features a rugged stainless steel outer casing for excellent corrosion resistance and mechanical strength. Sealing is managed by an aluminium Plug-in™ system with tungsten carbide faces to protect the motor from moisture ingress. Motor safety is reinforced by Class H stator insulation (180°C) and integrated thermal contacts that trigger an automatic safety shut-off if internal temperatures reached the 140°C threshold.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eOpen-hydraulic system with Hard-Iron® impeller optimized for abrasive site dewatering duties.\u003c\/li\u003e \u003cli\u003eSingle-screw impeller adjustment system allowing for precise maintenance of hydraulic clearances.\u003c\/li\u003e \u003cli\u003eReliable 5.6 kW three-phase induction motor with Class H insulation rating for safe operation.\u003c\/li\u003e \u003cli\u003eRugged stainless steel outer casing providing superior durability in contaminated industrial liquids.\u003c\/li\u003e \u003cli\u003eAdvanced Plug-in™ mechanical seal system with tungsten carbide faces for superior motor protection.\u003c\/li\u003e \u003cli\u003eInternal thermal protection contacts with a 140°C opening threshold embedded in the motor windings.\u003c\/li\u003e \u003cli\u003eStandardized 100 mm discharge connection optimized for high-volume liquid transfer and efficiency.\u003c\/li\u003e \u003cli\u003eDurable SUBCAB® submersible cable with screened control cores offering high mechanical safety.\u003c\/li\u003e \u003c\/ul\u003e ","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50888525938935,"sku":"2640.181.MT.K234","price":0.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0927\/0116\/3767\/files\/lowara-flygt-2640-stainless-steel-medium-head-free-flow-drainage-pump-civil-excavations-open-impeller.png?v=1782384930","url":"https:\/\/foundationpumps.com.au\/products\/lowara-flygt-2640-stainless-steel-medium-head-free-flow-drainage-pump-civil-excavations-open-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
