This series achieves a maximum submerged depth of 3.6 meters. It employs a dual-support structure: above the liquid level, two rows of angular contact ball bearings bear axial loads; below the liquid level, one or two pairs of sliding bearings (i.e., shaft sleeves and bushings) bear radial loads. The flow-through components are crafted from high-quality JSB alloy material, resistant to high-temperature sulfuric acid corrosion, ensuring long service life.

Application Scope:

Used in drying and absorption cycle systems of sulfuric acid production, as well as for conveying finished concentrated sulfuric acid. Suitable for transporting sulfuric acid at temperatures ≤120°C with concentrations ranging from 93% to 98%, or fuming sulfuric acid at temperatures ≥105°C.

This makes them ideal for processes such as acid recovery systems, chemical dosing lines, and finished product transfer in heavy industrial settings.

Corrosion‑Resistant Concentrated Sulfuric Acid Pump with Enhanced Materials

A corrosion‑resistant concentrated sulfuric acid pump with enhanced materials is specifically built to tackle the challenges of pumping strong corrosive liquids. Utilizing high‑performance alloys, special cast iron, or fluoroplastic‑lined components, these pumps resist chemical attack and maintain structural integrity over extended service cycles. The use of advanced seal designs, such as silicon carbide or ceramic seal rings, enhances leak prevention and improves operational safety. In addition, these pumps support a wide operating temperature range, making them suitable for applications involving both ambient and elevated temperatures in industrial acid handling. Their corrosion‑resistant construction not only ensures improved reliability and reduced downtime but also helps maintain performance in demanding environments where concentrated sulfuric acid and other aggressive chemicals are present. These features make corrosion‑resistant concentrated acid pumps indispensable in chemical processing, wastewater treatment systems, and acid circulation workflows.

High-Performance Concentrated Sulfuric Acid Pump for Continuous Industrial Operation

The concentrated sulfuric acid pump series is specifically engineered for the continuous handling and transfer of high-concentration sulfuric acid, including solutions ranging from 93% to 98% and fuming sulfuric acid at temperatures exceeding 105°C. Designed for industrial chemical processes, these pumps are ideal for drying towers, absorption cycle systems, and finished acid transfer operations in chemical plants, refineries, and industrial facilities. The pump’s design ensures stable performance under high-temperature and highly corrosive conditions, minimizing downtime and maintenance requirements.

This series features a maximum submerged depth of 3.6 meters, allowing continuous operation below the liquid level and eliminating priming issues. The dual-support bearing structure is engineered for durability: above the liquid level, two rows of angular contact ball bearings manage axial loads efficiently, while below the liquid level, sliding bearings (shaft sleeves and bushings) provide robust radial load support. This combination guarantees optimal load distribution, extended service life, and reliable long-term operation under heavy-duty industrial conditions.

All wetted components are manufactured from high-quality JSB corrosion-resistant alloy, selected for its superior resistance to sulfuric acid attack and high-temperature degradation. The materials maintain structural integrity while preventing erosion, wear, and chemical damage, ensuring the pump’s reliability in both continuous and batch operations. Advanced mechanical seals and precision-engineered flow-through components further reduce leakage risk, allowing for safe and efficient acid transfer across a variety of industrial applications.

This pump series also functions effectively as a high-temperature acid pump, chemical transfer pump, and industrial chemical pump, offering precise fluid handling for both concentrated acid and fuming sulfuric acid. Its centrifugal design optimizes hydraulic performance, providing smooth flow, low vibration, and consistent pressure under varying operational conditions. These features make the pump ideal for acid recovery systems, chemical dosing lines, and circulation processes in high-concentration sulfuric acid production.

In summary, this concentrated sulfuric acid pump combines deep-submerged design, dual-support bearing structure, advanced corrosion-resistant materials, and precise hydraulic engineering to deliver exceptional durability, operational safety, and high efficiency. It is a reliable solution for chemical industries requiring long-term, continuous operation in challenging acidic and high-temperature environments, making it indispensable for industrial sulfuric acid processing, transfer, and circulation applications.
