PRODUCTS ABOUT US contact

By self developing the tacloid tooth in our Daido Hailong (Shanghai) Co. Ltd. in the Waigiao Free Trade Zone (100% share held by Daido Machinery Corporation), we made possible the combination of high superior performance and low cost.

■Features

Higher fluid displacement per tooth

Less vibration and noise during operation due to smooth combination of rotor and idler.

Operation per lower electricity.
