Product Features
Energy efficient: Applying the most advanced NRCE design software and CFD fluid simulation software to develop and design the high efficiency hydraulic model,through the analysis of pump flow field,temperature field and strength,thermal deformation,fracture,rotor dynamics,etc,to achieve high efficiency ,reliability and wide efficiency zone,we have made the pump satisfy the efficiency and reliability requirements of centrifugal pump operating under design conditions and non-design conditions, reaching the international advanced level.
Rear opening type structure:The maintenance is convenient,It is not necessary to disassemble the suction and discharge pipes during maintenance to pull out the rotor parts for maintenance
Quality assurance:Before casting,the imported chemical analysis of the materials was carried out by the direct reading spectrum analyzer introduced from Britain to ensure that the material composition meets the requirement.The pump impeller and rotor components are tested by precise dynamic balance test,so the pump can run more smoothly, have less vibration and noise and longer service life.
