4kw 5.5HP 2.5" Cast Iron Non-Cloggingr Submersible Sewage Pump

Structure Instructions:1.Pump body and impellerPump body and impeller are well matched by the repeated modifications and designs with AutoCAD technology. Hydraulic model is high efficient, curve of output is flat , chich can't easily lead to overload. The impeller is strictly balanced to reduce the minium degree and extend the life of bearing and mechanical seal to the greatest extent.2. MotorMotor with protection grade IP68 can work under water, making the best cooling effection. It is more endurable than common motor.3.Mechanical SealMechanical seal of motor is made of high quality double mechanical seal or 2 sets of individual single mechanical seal which makes reliabl sealing line of defense. Under normal usage, non-falilure operation time exceeds 8000h4.BearingBearings are all high quality deep groove ball bearings which constitute reliable support for shaft or motor and pump, leads larger baering margin of radial force, axial force and other forces produced when the pump is working and make sure smooth running and long life of the whole set.ApplicationFor waste water discharge of industry, shopping mall, hospital, hotel.For domestic sewage and storm-water drainage of uptown, parking lot and municipal engineering.For sewage discharge of sewage treatment plant and farm.For pumping muddy water and lye of construction factory and mine.For pumping clean water of agriculture and aquaculture.SpecificationInsulation class: FProtection class: IP68Starting method: reduced-voltage startingWater temperature: up to 40ºCPH: 6 -10Density of liquid: 1.3g/cm³Power supply: three-phase 380V±10%, 50Hz, 220V or 440v/60Hz                          three-phase 220V or 440v ±10%, 60Hz                          single-phase 220V±10%, 50Hz                          single-phase 110V±10%, 60HzCapacity: up to760m³/hHead: up to 44mMaximum immersion depth: 20mCable length: 8m/* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
