Air-Operated Double Diaphragm Pump, PVDF body, PTFE diaphragm， highly corrosive chemical pump 1 inch 17GPM (QBZ-25PVDF)

The molecular formula of PVDF is Poly (vinylidene-fluoride), which has extremely high tolerance to most acids, bases, and organic solvents, and has high mechanical strength, wear resistance, and impact resistance

• Differences between PVDF and PP: PVDF withstands highly corrosive acidic and alkaline liquids, while PP withstands mildly corrosive acidic and alkaline liquids.
• APPLICATIONS: Pumps for transporting highly concentrated chemical liquids such as hydrochloric acid, sulfuric acid, hydrofluoric acid, nitric acid, aqua regia, etc. Zinc and copper prohibited. Dosage pumps.
• Seals feature： Teflon + TPE diaphragms and PVDF balls, offering corrosion resistance and extended service life through enhanced tensile and shrinkage tolerance. Maximum Temperature: 120°C Maximum Pressure: 100 psi Maximum Flow Rate: 17.6 GPM Maximum Head: 50 m
• Key Features: Lubrication-free operation with self-priming capability Capable of continuous 24-hour operation Dry-running without pump damage Complete separation between pumped medium and pump components Suitable for handling toxic substances Resistant to corrosion and leakage Low energy consumption with minimal gas usage Modular design Low maintenance costs and extended service life
• Advantages: Spark-free, anti-static, flow rate and head adjustable via air source pressure switch.
