In the chemical, pharmaceutical, and environmental sectors, reliable fluid transfer is critical to maintaining continuous production. Leveraging 26 years of deep experience serving the chemical industry, Yuanfang Group introduces the STFF Series Pneumatic Double Diaphragm Pump – a robust, maintenance-friendly solution designed to handle corrosive media, high-viscosity fluids, and particle-laden liquids.

Diaphragm Pump for Chemical is an air-operated positive displacement pump that uses the reciprocating motion of two flexible diaphragms to create suction and discharge. Its unique design completely isolates the pumped medium from the pump’s working parts, eliminating leakage risks and making it ideal for transferring acids, alkalis, solvents, resins, and sensitive pharmaceutical intermediates.

Diaphragm Pump for Chemical Key Features

1. Superior Corrosion Resistance & Material Flexibility
   All wetted parts are available in a range of high-performance materials – PTFE, Polypropylene (PP), 316L Stainless Steel, or custom alloys – to match your specific fluid chemistry. Whether handling hydrochloric acid, sulfuric acid, caustic soda, or organic solvents, the STFF ensures long service life.

2. Leak-Proof & Intrinsically Safe Design
   The sealless, closed structure eliminates the “run, leak, drip” problems common with centrifugal pumps. Powered by compressed air, it requires no electricity, making it inherently explosion-proof and safe for use in pharmaceutical workshops, solvent recovery areas, and other hazardous zones.

3. Excellent Self-Priming & Solids Handling
   With a dry self-priming capability of up to 7 meters, the STFF easily handles low sump levels. Optimized ball valves and flow paths allow passage of solids up to 10 mm, and the pump excels at transferring high-viscosity fluids without performance loss.

4. Gentle Pumping Action & Low Maintenance
   The diaphragm action minimizes shear, preserving the physical properties of shear-sensitive media like emulsions, latex, and biological slurries. The simple design (mainly diaphragms and ball valves) means easy maintenance – worn parts can be replaced quickly without special tools, reducing downtime.

5. Modular & Compact Construction
   The STFF series features a modular design for easy installation and integration into existing skids or systems. Its compact footprint saves valuable floor space.
