Product Description
The fluoroplastic chemical pump is a centrifugal pump with PTFE/PFA-lined wetted components, offering exceptional corrosion resistance for handling highly aggressive chemicals. The fluoroplastic lining provides a barrier against acids, alkalis, oxidizers, and solvents that would attack standard metal pumps. The pump features a metal casing lined with fluoroplastic, combining the mechanical strength of metal with the chemical resistance of fluoropolymers.
Applications
- Sulfuric acid transfer
- Hydrochloric acid
- Nitric acid handling
- Caustic soda
- Oxidizing chemicals
- Pharmaceutical processing
Quality Assurance
All pumps are manufactured under ISO 9001 quality management system. Each pump undergoes rigorous testing including hydrostatic pressure test, performance test, NDT inspection, and dynamic balance verification before shipment. We provide comprehensive documentation including test reports, material certificates, and operation manuals.
Why Choose Our Chemical Centrifugal Pumps
Fluoroplastic Lined Corrosion Resistance
PTFE/PFA lined wetted parts handle strong acids (HCl, H2SO4, HNO3), alkalis, and halogenated solvents that would rapidly corrode stainless steel. Liner thickness 3-5 mm with spark test verification.
PFA Liner for High Temperature
PFA liner option rated for continuous operation up to 150°C, suitable for hot acid circulation and chlor-alkali process service beyond standard PTFE limits.
Back Pull-Out Maintenance
Rotating assembly removes without disturbing piping, with fluoroplastic lined impeller and casing cover. Liner integrity verified by high-voltage spark test after reassembly.
Zero Metal Contact
All wetted surfaces fully lined with fluoropolymer, ensuring no metal ion contamination for high-purity chemical and semiconductor applications.

Selection Guide
✅ When to Choose This Pump
- General chemical transfer and circulation
- Acids, alkalis, and solvents at moderate temperatures
- ISO 2858 standard dimension interchangeability
- Plants requiring easy maintenance and spare parts
⚠️ When NOT to Choose
- Highly abrasive slurries (use slurry pump)
- Zero-leakage requirements for toxic fluids (use magnetic drive)
- High viscosity above 500 cP (use PD pump)
- Self-priming needs (use self-priming pump)
💡 Common Selection Mistakes
- Selecting wrong material for chloride-containing fluids
- Not accounting for viscosity derating
- Using standard seal for crystallizing fluids
- Ignoring suction piping design for low NPSH
