In February 2026, Changyu Pump completed a sulfuric acid transfer pump project for a material manufacturing company in Indonesia. The project focused on upgrading the sulfuric acid pumping system in the customer’s sulfuric acid workshop by replacing the existing equipment with a CYQ series magnetic drive chemical pump. The customer required a safer and more reliable pumping solution for concentrated sulfuric acid transfer. The previous equipment had leakage risks, high maintenance requirements, and unstable operating performance, which affected continuous production.
After installation and commissioning, the new pumping system achieved stable operation with no leakage issues and significantly reduced maintenance requirements.

Project Background
The customer is a material manufacturing company in Indonesia. Its sulfuric acid workshop plays an important role in the production process and requires a reliable pumping system for continuous and safe sulfuric acid handling.
Concentrated sulfuric acid has strong corrosiveness and oxidizing properties. Therefore, pumping equipment must provide excellent corrosion resistance, reliable sealing performance, and long-term operating stability.
During operation, the customer’s original pumping equipment experienced several challenges:
- Leakage Risk from Mechanical Seals
- The traditional mechanical seal pump required regular seal maintenance. After long-term operation, seal wear could cause sulfuric acid leakage, creating potential safety risks for operators and the working environment.
- High Maintenance Cost
- Due to the corrosive nature of sulfuric acid, the original pump required frequent replacement of sealing components and wetted parts. This increased spare parts costs and extended maintenance downtime.
- Unstable Operating Performance
- The previous equipment showed fluctuations in flow rate and head performance, affecting the stability of downstream processes and production control. To solve these problems, the customer needed a more reliable sulfuric acid transfer pump solution with better corrosion resistance and sealing performance.
Changyu’s Sulfuric Acid Transfer Pump Solution
Based on the customer’s operating conditions, Changyu recommended the CYQ series magnetic drive chemical pump.
This pump is designed for transferring corrosive chemical media where leakage prevention and long-term reliability are critical. The magnetic drive structure eliminates the traditional shaft seal design and provides a safer solution for concentrated sulfuric acid transfer applications.

Why CYQ Magnetic Drive Pump Was Selected
The CYQ pump was selected based on the customer’s sulfuric acid operating conditions and the requirements for safe and stable operation.
- Eliminating Leakage Risk
- The CYQ magnetic drive pump uses a seal-less structure and removes the need for a traditional mechanical shaft seal.
- For concentrated sulfuric acid transfer, this design significantly reduces the possibility of leakage caused by seal wear and helps create a safer operating environment.
- This makes it an ideal magnetic drive pump for sulfuric acid applications where leakage control is a key requirement.
- Excellent Corrosion Resistance
- The pump wetted components use FEP-lined construction, with lining thickness reaching 8-15 mm.
- FEP lining provides excellent corrosion resistance and is suitable for demanding sulfuric acid applications. It helps maintain stable pump performance during long-term operation and extends service life in corrosive environments.
- Lower Maintenance Requirements
- Because the magnetic drive design eliminates mechanical shaft seals, regular seal replacement is no longer required.
- Combined with corrosion-resistant materials, the CYQ pump reduces spare parts consumption and maintenance frequency, helping customers lower operating costs and improve production continuity.
Comparison Before and After Implementation
| Comparison | Previous Equipment | CYQ Magnetic Drive Pump |
| Safety | Mechanical seal leakage risk existed during operation | Sealless structure reduces leakage risk and improves workplace safety |
| Maintenance Cost | Frequent seal replacement and high maintenance requirements | Low maintenance demand with no mechanical seal replacement |
| Operating Stability | Flow and head fluctuations affected process control | Stable operation with reliable performance |
| Production Efficiency | Unplanned downtime affected production schedules | Longer continuous operation time and improved production reliability |
| Overall Cost | High spare parts, maintenance, and downtime costs | Lower lifecycle cost and improved return on investment |
