Gas-Liquid Two-Phase Flow Endurance Test: Suofu Micro Magnetic Gear Pump Performance

Collaborating with Top University Research Capabilities to Empower Future Technology.

Suofu's micro magnetic gear pump has been successfully applied in a key research project of the School of Energy and Power Engineering at Huazhong University of Science and Technology—a long-term endurance testing system for gas-liquid two-phase flow. It provides a stable and reliable fluid delivery solution for this demanding and rigorous research environment.

▍ Project Challenge: Stringent Requirements of Gas-Liquid Two-Phase Flow Testing

This project at Huazhong University of Science and Technology aims to simulate the flow characteristics and equipment endurance under extreme industrial conditions involving gas-liquid mixed media, placing extremely high demands on the core fluid equipment:

• Media Complexity:​ Requires stable delivery of gas-liquid two-phase fluid with dynamically varying gas content.

• Long-Term Continuity:​ Testing must run continuously for thousands of hours, demanding pump equipment operate without failure.

• Pressure Stability:​ Outlet pressure must remain stable to avoid pulsation interference with data acquisition.

• Zero-Leakage Safety:​ The experimental environment strictly prohibits media leakage, ensuring safety and data accuracy.

▍ Suofu Solution: NP Series Micro Magnetic Gear Pump

To address the aforementioned requirements, Suofu provided customized NP series magnetic gear pumps, whose core advantages perfectly match the experimental needs:

• Gas-Liquid Two-Phase Delivery Capability:​ Special cavity design allows handling of gas-liquid mixed media with gas content up to 100% within specified speed ranges.

• Long-Term Endurance:​ Ceramic shaft combined with PEEK gears results in extremely low wear, enabling continuous operation for >20,000 hours maintenance-free.

• Fully Sealed Structure:​ Magnetic drive mechanism completely eliminates leakage, meeting laboratory safety and cleanliness requirements.
