3. Free head and free flow through the valve opening level adjustment ( pneumatic adjustment between 1-7bar );


4. No rotating parts of the pump, no seal. diaphragm pumps and pumping media, such as moving parts, the pumping media such as diaphragms are totally separated from the moving parts,and the workpiece. the transmission medium will not leak out. Therefore, when pumping toxic, volatile or corrosive medium, it won't cause environmental pollution and will keep men safe;


5. You don't need electricity. They are safe and reliable to use in flammable, explosive places;

7. Easy to use, reliable work,for start and stop you can simply turn on and turn off the gas valve. Even if no media running for a long time due to unforeseen circumstances or suddenly shut down, pumps will not be damaged. Once overloaded, the pump will automatically shut down, with a protective performance; when the load is restored, it can automatically start running again;


8. Unlike other types of pump, simple structure, low spare parts and simple structure make it easy to install and to maintenance. Media would have had access to the distribution of the pump valves, connecting rod and other moving parts;
