    Designed on the basic of IS single stage centrifugal.
    Take advantage of virtues of ISG pump, performance date according to ISO2858 standard and product quality performs JB/T53062-93 standard so the technical performance is advanced in domestic congener products.
    The motor and pump are joined directly without transmission parts. So they operate smoothly. Compared with common horizontal pump. PTW series can decrease 30 percent floor space. The shaft seal is made with hard alloy mechanical seal whose working life is long-Besides, the pump features low noise, convenient maintenance and light shake.

    With compact structure,be applicable especially formodern construction.  
    Pump casting:it is a kind of pipes-joined spirai pump casing,adpot the best hydraulic model to design. The suction and discharge nozzles have the diameter of same dimension,and the centers of the  circles are in the same line.        
    Impeller:it is a kind of enclosed cast iron inpeller ,and its best hydraulic model guarantees the efficiency and reliability of pump. 
   Mechanical seal :it is free of  mainfenance and free to rotation if used in the water below 80º or 120º. The special  design for dynamic ring can guarantee the reliability of seal.

     Directly connected with the motor ,a center for the motor ,the pump and shaft and so has less  vibration and low noise. 
     The outlet and inlet are the same in diameter and  the diameters are in the same line ,so ,the pump can mounted wherever on the pipeline ,just like valves .  
     Use the circulation-enforced way to improve the running environment of menchanical seal ,which canprolong the life of mechanical seal.
     Special type of mechnaical seal enforcing cirulation regaardless of rotation directions can improve the working environment and elongate the life.
      Vertical installation reduces occupation of pump ,which saves the  invest cost  by 40%~60%. 
      Perfect design  ensures its no leakage and long life ,which can save the operation cost by 50%~70%.  
      Adopt the high-quality casting off ,which results in high accuracy in dimension and nice-looking appearance.
      The motor is made by domestic famous factory ,which can ensure the quality of motor. 
      This series is of pumps are specially designed to bo mounted directly onto pipeline .During the installation ,it is effective to any direction except the head of motor downward .For pumps with the matching power more than 7.5KW , suggest you use the pulley in the installation  and maintenance.
