Diaphragm pump is a dry operated vacuum pump that completely solves the problem of chemical corrosion resistance of vacuum pumps. It is particularly suitable for situations that require resistance to chemical corrosion or long-term uninterrupted operation. All parts in contact with the gas are treated with polytetrafluoroethylene (PTFE) and reinforced with carbon fiber, fully ensuring the pump's resistance to chemical corrosion. The diaphragm adopts a sandwich structure (i.e. multi-layer structure) to increase its toughness and strength. Diaphragm pumps are currently at the forefront of international vacuum pump development and are increasingly being used in China. The main advantages of diaphragm pumps are:
·Vacuum stability and easy control
·Complete resistance to chemical corrosion
·No water consumption, strong environmental performance
·Small size, light weight
·Easy to use, clean
·Can work sustainably and stably
Maintenance and repair are both very convenient

The main application scenarios of diaphragm pumps are:
·vacuum distillation
·reaction kettle
·vacuum filtration
·Vacuum concentration
·vacuum drying
