This PTFE diaphragm pump is widely used across multiple industries including:
- Waste water treatment plants
- Chemical and petrochemical processing
- Painting and coating applications
- Ceramics manufacturing
- Environmental protection systems
- Printing and dyeing operations
Ideal for handling corrosive, volatile, flammable, toxic fluids with particles and high viscosity.
The pump features two symmetrical pump chambers equipped with PTFE diaphragms connected by a center couplet stem. Compressed air enters through the inlet valve, driving diaphragm movement in alternating chambers to create continuous synchronized reciprocating motion. This design ensures reliable fluid transfer while preventing backflow through integrated ball valve systems.
