Teflon pneumatic diaphragm pump

Teflon pneumatic diaphragm pump

Teflon air-operated diaphragm pumps feature PTFE diaphragms and wetted parts, handle fluids with a pH range of 0–14, operate at air pressures up to 7 bar (100 psi), deliver flow rates up to 60 m³/h, and allow 100% dry-running without damage.

Main Structural Features

• Center air valve system ensures smooth shifting and reduces air consumption by 20–30%.
  
• Flexible diaphragm stroke handles solids up to 3–5 mm without clogging.
  
• Low-shear pumping protects sensitive or volatile chemicals during transfer.
  
• Self-priming up to 5–6 m for reliable suction-lift operation.

 Materials

• Diaphragm: PTFE (Teflon)
  
• Wetted Parts: PTFE, PFA, PVDF, or corrosion-resistant plastics.
  
• Air Valve & Housing: Teflon,Aluminum or stainless steel (depending on model).

 Applications

• Chemical Transfer: Strong acids, alkalis, and solvents.
  
• Wastewater Treatment: Sludge, slurry, and corrosive effluents.
  
• Electroplating & Surface Treatment: Chemical dosing and circulation.
  
• Pharmaceutical & Food Processing: Safe transfer of sensitive chemicals with low contamination risk.

FAQ for Teflon pneumatic diaphragm pump:

Q: What is the typical lifespan of the PTFE diaphragm in these pumps?

A: Under normal operating conditions, PTFE diaphragms can last 10,000–20,000 hours, depending on chemical type and duty cycle.

Q: Can Teflon pneumatic diaphragm pumps handle volatile or flammable chemicals?

A: Yes, because they are air-driven and electrically safe, making them suitable for transferring volatile or flammable chemicals in hazardous environments.
