Customers’ Satisfaction is Our Pursuit

Leaders of Jiang Su Petroleum Exploration Bureau of Sinopec Group go to Hunan Changhe pump co.,Ltd to inspect and test the pumps for the brine transport pump project from December 30th to December 31st. In the morning of December 30th,our pumps successfully pass the test with every technique data meet or exceed the requirement of the contract, especially the vibration of pump reach 1.5mm/s. From the picture above, we can see a coin can be solidly placed on the pump. In the afternoon of December 31st,the dynamic balance testing begins. Although the test is not required for the pump which rotating speed is less than 3000, in order to assure the customers, we still proceed the test and enhance test standard from level 2.5 to level 1.6. Customers’ favorable comment greatly inspired us., and customers’ satisfaction is our pursuit.
