Feature
-
StonyLab diaphragm pump operates in two stages and handles gas media, while being both pollution-free and maintenance-free.
-
All components that come in contact with gas are constructed using polytetrafluoroethylene (PTFE) material, which is highly resistant to corrosion and suitable for a wide range of applications.
-
To enhance the pump's corrosion resistance, special diaphragms with composite PTFE coatings and pump head designs are employed.
