1. Because air is used as power, the flow rate is automatically adjusted with the change of back pressure (outlet resistance), which is suitable for medium and high viscosity fluids. The working point of centrifugal pump is set on the basis of water. If it is used for fluid with slightly higher viscosity, it needs to be matched with reducer or variable frequency governor, which greatly increases the cost, and the same is true for gear pump.
2. Pneumatic diaphragm pump is reliable and low-cost in flammable and explosive environment. Third, the fluid will not overheat because the diaphragm pump has the smallest disturbance to the fluid.
3. In harsh places, such as construction sites, industrial and mining wastewater discharge, because of the many impurities and complex components in sewage, the pipeline is easy to plug, thus forming a situation of excessive load on the pump, and the motor is vulnerable to heat. Pneumatic diaphragm pump can be adjusted by particles and flow rate. When the pipeline is blocked, it stops automatically until it is unobstructed.
4. Pneumatic diaphragm pump is small and easy to move, does not need foundation, occupies a very small area, and is easy to install and economical. It can be used as a mobile material delivery pump.
5. In the hazardous and corrosive material treatment, the diaphragm pump can completely separate the material from the outside world.
6. Pneumatic diaphragm pump can be used to transport fluids with unstable chemical properties.
The role of pneumatic diaphragm pump in the industrial field is huge, many difficult to be completed by human hand can be completed by pneumatic diaphragm pump, indirectly ensuring the safety of employees.
