Sulfuric Acid Pump and API 610 Solutions for Petrochemical and Refinery Plants
Sulfuric Acid Pump for Petrochemical Desulfurization and Refinery Applications
Handling Concentrated Acid in Refinery Environments
Refinery desulfurization units generate large volumes of sulfuric acid that require continuous, leak-free transfer. Therefore, our sulfuric acid pump series uses JSB alloy construction to resist corrosion at 93–98% H₂SO₄ concentrations. Furthermore, API 610 compliance ensures safe integration into high-pressure refinery systems.
Reliable Performance in Catalytic and Cracking Circuits
Beyond desulfurization, these pumps also serve catalytic reforming, alkylation, and crude distillation units. As a result, plant engineers maintain stable acid circulation across multiple process stages without changing pump platforms. Moreover, the axially split casing design simplifies maintenance during scheduled turnarounds.
Concentrated Sulfuric Acid Pump for Alkylation and Acid Recovery Units
Designed for Fuming and Concentrated Acid Service
Our concentrated sulfuric acid pump handles both 93–98% H₂SO₄ and oleum at ≥105% concentration reliably. In addition, the JSB alloy material achieves a corrosion rate below 0.1 mm/a at 120°C. Consequently, refineries and petrochemical plants extend pump service life up to 300% compared to standard alloy alternatives.
Stable Flow for Acid Recovery and Neutralization
Acid recovery units require pumps that maintain consistent flow under variable feed concentrations. Furthermore, the vertical submerged design prevents external leakage and reduces fugitive emission risks. Therefore, environmental compliance teams specify this pump for acid recovery and spent acid transfer applications.
Acid Dosing Pump for Chemical Injection and pH Control in Petrochemical Plants
Precision Dosing for Process Chemical Management
Petrochemical plants use acid dosing systems to control pH, inhibit corrosion, and manage chemical reactions across multiple process units. Therefore, our acid dosing pump delivers precise, repeatable flow rates for sulfuric acid, hydrochloric acid, and chemical additives. Furthermore, the intelligent IoT-enabled version supports remote monitoring and automatic adjustment.
Compact and Reliable for Continuous Chemical Injection
These pumps integrate easily into existing DCS and SCADA systems without complex modifications. As a result, chemical engineers implement accurate dosing control with minimal installation time. Moreover, corrosion-resistant materials ensure long service life even when handling highly aggressive injection chemicals.
Why Petrochemical Plants Rely on Precision Acid Dosing Systems
Consistent Accuracy Under Variable Process Conditions
Dosing accuracy remains stable across a wide flow range, which is critical for pH control in wastewater and process streams. In addition, the diaphragm design eliminates seal leakage risk when handling toxic or volatile acids. Consequently, plant operators achieve tighter process control and lower chemical consumption.
Compliance with Safety and Environmental Standards
All acid dosing pump models comply with CE and API Spec Q1 certification requirements. Furthermore, leak-free construction reduces fugitive emission risks in enclosed refinery environments. Therefore, HSE teams approve these pumps as the preferred chemical injection solution for critical petrochemical applications.
