Pneumatic diaphragm pump has a small volume, is easy to move, occupies less space, and is simple and economical to install Pneumatic diaphragm pumps can pass particles and have adjustable flow rates Due to the use of air as a power source, the flow rate will automatically adjust with changes in back pressure (outlet resistance), making it suitable for medium to high viscosity fluids When dealing with hazardous and corrosive materials, pneumatic diaphragm pumps can isolate the materials from the outside world It can be used to transport fluids with relatively unstable chemical properties, such as photosensitive materials and flocculants. This is because the shear force of pneumatic diaphragm pumps is low and has little physical impact on the material
