Testing
Zigong Pump built a comprehensive pump testing center which is the largest and most powerful one in Southwest China. With the supports of material laboratory, physical and chemical laboratory,mould sands laboratory, and advanced instruments of dynamic balance machine,optical spectrum analyzer, the quality control can be refined in the material inspection,components check,performance test,etc.
