This medium-head drainage pump is specifically engineered to handle liquids with high solid content in civil engineering zones where handling abrasive wastewater is a frequent requirement. It serves as a dependable solution for utility infrastructure, where high operational uptime and resistance to grit are essential.\u003c\/p\u003e \u003cp\u003eDriving the hydraulic curve of this 2640 MT variant is a robust 5.6 kW motor achieving a maximum head of 27.5 m and a maximum flow rate of 2460 L\/Min. Drawing a rated current of 10 Amps at 415v, the three-phase induction motor provides consistent power for large-scale waste management. The IP68 encapsulation allows for continuous immersion up to 20 meters, offering versatility for installation in diverse infrastructure sumps.\u003c\/p\u003e \u003cp\u003eEfficiency remains optimized through Dura-Spin™ technology, which uses a unique closed Hard-Iron® impeller and specialized suction cover to significantly reduce wear. This system is paired with the Spin-Out™ design that clearing abrasive grit dynamically from the seal chamber during rotation, protecting the mechanical seals. These engineering advancements ensure that energy consumption remains optimized and unplanned manual maintenance is kept to a minimum.\u003c\/p\u003e \u003cp\u003eMechanical protection is prioritized via a specialized Plug-in™ seal arrangement featuring tungsten carbide faces to safeguard the internal electrical assembly. Physical construction utilizes high-grade stainless steel for the outer casing and an aluminium stator housing for optimal thermal management under high load. Safety is further enhanced by Class H stator insulation and winding-embedded thermal contacts that safeguard against overheating during extended duty cycles.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFEATURES\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eAdvanced Spin-Out™ design expelling abrasive particles from the seal chamber to protect mechanical seals.\u003c\/li\u003e \u003cli\u003eDura-Spin™ unique closed impeller system made from Hard-Iron® for superior wear resistance.\u003c\/li\u003e \u003cli\u003eDurable stainless steel outer casing and aluminium stator housing for superior structural integrity.\u003c\/li\u003e \u003cli\u003ePowerful 5.6 kW three-phase induction motor with Class H insulation for reliable continuous service.\u003c\/li\u003e \u003cli\u003eLarge 100 mm discharge outlet optimized for high-volume transfer and minimal hydraulic turbulence.\u003c\/li\u003e \u003cli\u003eAdvanced Plug-in™ mechanical seal design with tungsten carbide faces for maximum motor protection.\u003c\/li\u003e \u003cli\u003eInternal thermal protection contacts with a 140°C opening temperature to prevent stator damage.\u003c\/li\u003e \u003cli\u003eHeavy-duty SUBCAB® power cable offering maximum mechanical strength and chemical compatibility.\u003c\/li\u003e \u003c\/ul\u003e ","brand":"Lowara","offers":[{"title":"Default Title","offer_id":50888525906167,"sku":"2640.181.MT.B226","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-dura-spin-drainage-pump-industrial-sumps-closed-impeller.png?v=1782384928","url":"https:\/\/foundationpumps.com.au\/products\/lowara-flygt-2640-stainless-steel-medium-head-dura-spin-drainage-pump-industrial-sumps-closed-impeller","provider":"Foundation Pumps","version":"1.0","type":"link"}
