Lower Noise Intra—Vane Pumps are developed by our company in order to suit the low noise demands in machine——tool industry．Altogether there are four series，nineteen breeds．The displacement range of it is 18—193mL／rev，and the highest continuous working—pressure is 17．2 MPa，and the range of revolution is 600一]80t}rpm．Using composite blade construction can

make it a long life to use and low noise．Together with high pressure and big rate of flow．Working steadily and higher compacity efficiency are the intrinsic attributes of the blade pump．Twelve—blade pump construction assures the little amplitude of the pulsating flow，and the low noise of the system．The shell design is of quality shock absorption，which makes the noise the lowest and aduances the comfort of operation．The main specification of technique achive the advanced level among the same soft of products around the world．This series of pump using the insert construction．Can be repaired on the spot’，which compresses the time of repairation and raise working efficiency．The machine core module tested in the factories can supply the performance of new pumps ofter instauation．The mouths of oil input and Output can make various positions，which supply great flexibility of installation and is convenient to design．
    This series blade pump is of complete variety sperification and excellent and reliable function．Its simple and rational construction makes the installation and repairation more convenient．The connection of installation accords with ISO/SAE standard，which can be used widely for machine—tool and plastic machinery and variety hydraulic pressure systems．
