With compact structure,be applicable especially formodern construction.    
      Pump body: the spiral casing with pipe connecting is designed and manufactured by the most superior bydraulic model nowadays ,with inlet an outlet in a straight line and of the same diameters . Flanges conform to GB4216.5,and are equipped with Rp1/4 or Rp3/8 pressure testing hole..   
      Impeller:closed cast iron impeller and excellent hydraulic model to ensure high efficiency and dependability.
     Mechanical seal :maintenance-free and no limit to rotation direction under the water below 80℃or 120℃. The special  design of rotation seal ring to ensure high seal dependability.


     Directly connected by motor ,complete concentricity of moter and punp shaft ,little vibration and low noise.   
     Same diameters of inlet and outlet diameters in a straight line ,so that it can ,just like a valve ,be mounted at any a position in pipeline .  
     Specially structure bearing using a whloe shaft for dependable operation.  
     The operating conditions of mechanical seal improved by compulsory circulating flow ,thus to lengthen the operation life of mechanical seal .  
     Vertical installation structure to greatly lessen the floor occupation of pump ,saving construction investment by 40%~60%.  
     Perfect design to ensure leak-tightness and long-time operation,saving operatiing management cost by 50%~70%.   
     Quality castings,high dimensional accurcy and elegant outline.
     Motor supplied  by famous motor manufactuer at home to ensure goog quality.  
     This series is of pumps are specially designed to bo mounted directly onto pipeline .Upon installation ,except that the head of motor cannot be turned downward ,all other installation  postions will be no problem .For pumps over 7.5KW power ,it is suggested to use hoisting pulley in installation  and maintenance.
