DCZ Series Phosphoric Acid Pump – Engineered for Safe & Efficient H₃PO₄ Transfer
The DCZ series Phosphoric Pump by XJY Pump is a specialized corrosion-resistant centrifugal pump designed for the reliable handling of phosphoric acid (H₃PO₄) across concentrations from 10% to 85% and temperatures up to 120°C. Built with PTFE or PVDF lining and available in sealless magnetic drive or double mechanical seal configurations, this pump ensures zero leakage, long service life, and compliance with stringent safety standards in fertilizer, chemical, food additive, and metal treatment industries.
Why Standard Pumps Fail with Phosphoric Acid?
Phosphoric acid-especially at elevated temperatures or concentrations-rapidly corrodes carbon steel, cast iron, and even some stainless steels. Impurities like fluorides or sulfates accelerate wear. The DCZ series phosphoric acid pump solves this with:
* Full wetted parts lined with PTFE or PVDF – inert to H₃PO₄ at all common industrial concentrations
* No exposed metal in fluid path – eliminates pitting, cracking, and contamination
* Leak-proof design – critical for toxic fumes and environmental compliance
Key Features of DCZ Phosphoric Acid Pump
* Material Options: PTFE-lined (up to 120°C), PVDF-lined (up to 90°C), or solid PVDF construction
* Sealless Magnetic Drive: Ideal for high-purity or hazardous applications (no seal maintenance)
* Mechanical Seal Version: For high-pressure systems requiring ANSI/API compatibility
* Flow Range: ≤ 2000 m³/h | Head: Up to 160 meters
* Horizontal End-Suction Design: Easy installation, maintenance, and pipeline integration
* ISO 9001 Certified Manufacturing with full material test reports (MTRs)
