Chemical Pump
Engineered to handle aggressive acids, alkalis, solvents, and reactive fluids under extreme pressure and temperature, DEFU chemical transfer pumps deliver precision, safety, and corrosion-resistant durability.
Constructed from robust SS316, PVDF, PP, or PTFE, these pumps ensure leak-free operation in hazardous environments—from high-viscosity slurries to volatile compounds.
DEFU offers two core solutions:
- AODD (air-operated diaphragm) pumps, ideal for solids handling, shear-sensitive fluids, and dry-run conditions.
- Centrifugal pumps, known for energy-efficient, high-flow performance in continuous processing.
Both designs are engineered for precision dosing, batching, and mixing, minimizing environmental risks and downtime across:
- Chemical manufacturing
- Petrochemical refining
- Wastewater treatment
These pumps prioritize operational safety, material resilience, and hydraulic accuracy—ensuring long-term, reliable performance in the most corrosive and demanding applications.
