The advantages of pneumatic diaphragm pump are: 1. Because it is powered by air, the flow is automatically adjusted with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. The working point of the centrifugal pump is set based on water. If it is used for the fluid with higher viscosity, it needs to be equipped with a reducer or a frequency converter, which will greatly increase the cost. The same is true for gear pumps. 　　

We should also make it clear that the pneumatic ball valve should be properly inspected and maintained when it is used. The main purpose of this is to timely lubricate the areas lacking lubrication and clean the dirty areas. And another aspect is to really ensure that small problems can be found in time to avoid these problems becoming big problems. Taking the actual situation of this aspect into consideration, it is a guarantee that you can solve many small problems reasonably, and finally deal with the situation better.
