Flygt F-pump Series

Flygt F-pump seriesSelf-cleaning chopper pumps with sustained high efficiency

IntroductionFlygt chopper pumps cut sumpproblems down to sizeBroad range capacity Ratings from 1.7to 47 kW Flow up to 200 l/s Heads up to 81 mRough and rugged, Flygt F-pumpstackle the toughest wastewater challenges. By cutting solids or fibersdown to size, Flygt chopper pumpsensure reliable, trouble-free operation that’s energy efficient, too.Buy a ready-to-use Flygt F-pump orupgrade your Flygt N-pump for outstanding performance in heavy-dutywastewater applications.Well proven performanceFlygt F-pumps demonstrate unmatched reliability in installationsworldwide. These chopper pumpsperform like no other, handling whatever goes down the drain – from plastic bottles and wood to clothing andmotor cables.2Cost-effective operationFlygt F-pumps transport tough solidsand reduce operation and maintenance costs, too. Under extreme conditions, our energy-efficient chopperpumps run continuously with sustained hydraulic efficiency in heavyduty applications such as: Heavy-duty wastewater applications Food processing facilities Pulp and paper mills Heavy-duty sludge pumping Aqua culture Agricultural facilities Correctional facilities Public access facilitiesThe F-pump advantage Cuts tough solids Patented N-technology Innovative design Sustained highefficiency Self-cleaning ability Fewer unplanned service calls Factory-tested for highperformance

DesignChop it up with the provenN-impellerAdvanced N-technologyFlygt F-pumps feature patented Flygt N-technology,which is renowned for its self-cleaning capabilitiesand sustained high efficiency.N-impellerVirtually maintenance freeFlygt F-pumps feature the patented FlygtN-impeller, which rotates inside a chopper insertring. This rotation cuts all types of hard-to-pumpsolids, such as fibrous material, textiles and otherdebris into small, easy-to-pump pieces.Chopperinsert ringReliefgroovesGuide pinSelf-cleaning componentsTo prevent clogging, the Flygt N-impeller featuresa backswept design which together with the reliefgroove in the insert ring sweeps solid objects alongthe leading edge.Sustained high efficiencyAll components work together without sacrificingthe pump’s overall hydraulic performance. Pumpefficiency consistently remains high while keepingenergy costs low.Pump housingWear-resistant materialFlygt F-pump components consist of Hard-Iron material (HRC 60), which has proven to have exceptional wear resistance in tough wastewater applications.The Flygt cutting knife effortlessly chops food and fishmatter, including whole fish,into small, easy-to-pump solids.Available for 3127 and 3153.The Flygt feeding screwhandles material with a highdry-solid content with ease.Available for 3153.The Active Seal system, a patented zeroleakage double-seal system, actively preventsliquid from entering the motor cavity, therebyreducing the risk for bearing and stator failure.3

DesignEngineered for long lifeBETTER HEAT TRANSFEROur specially designed and manufactured motor provides enhanced cooling because heat losses are concentrated around the stator. Trickle impregnated inresin (Class H insulation), the stator windings are ratedat 180 C (355 F) and enable up to 30 starts per hour.Cable entryWater-resistant cable entry provides both sealing and strainrelief functions to ensure a safeinstallation.EFFICIENT COOLINGThese pumps are cooled either by the surrounding liquid or with an internal closed-loop coolingsystem.SENSORSThermal sensors embedded inthe stator windings prevent overheating, and an optional leakagesensor minimizes the risk for bearing and stator failure.INSPECTION CHAMBERTo increase operational reliability, an inspectionchamber between the seal unit and the bearingsenables rapid spot checks and maintenance. In thecase of a seal failure, a built-in sensor provides anearly warning of any fluid build-up, thus reducing the risk of expensive repair work. Standard for3153 and above.Long-life bearingsDurable bearings provide a minimum service life of 50,000 hours.ENDURING SEALSThe Flygt Plugin seal with the ActiveSeal system or Griploc seal offers increased sealing reliability and reducedrisk of bearing and statorfailure.complianceEach pump is tested and approved in accordance withnational and internationalstandards, including IEC34-1 and CSA. Pumps areavailable in explosion-proofversions for use in hazardous environments, and areapproved by the FactoryMutual, European Standardand IEC.Methods of installationFPFSFor semi-permanentwet well installations.The pump is installedwith twin guidebars on a dischargeconnection.4A semi-permanentfree standing installation.
