Mr.Alex is our old customer. He has successfully purchased five sets of diaphragm vacuum pump here. This time, because the company needed to order a batch of vacuum pump again, he found us again. I am very happy that we can cooperate again this time. This time, Mr.Alex needed the rotary vane vacuum pump. According to their parameters, we recommended the 2XZ rotary vane vacuum pump to him. The 2XZ type vacuum pump has the advantages of small volume, light weight, low noise and easy to use. Through an in-depth understanding of this product, Mr.Alex ordered ten sets of rotary vane vacuum pump from our company. I hope we can cooperate again and again!
