Recommendations for selecting low-flow sulfur pumps
Thread Content
Current status: The submersible gear pump is installed in the sulfur melting tank; each time it is used, waiting is required until the solid sulfur in the tank has melted (to 140°) before transportation can take place. The transfer rate is 30 L/h (which is relatively low), and fluctuations in this flow rate occur after about 3 months of use! Please, experts, give me some advice! Is it wear of the pump head gear set or some other cause? Any good recommendations?
In your case, the submersible gear pump may experience wear of the gear components due to high temperatures and solid sulfur, which can lead to fluctuations in flow rate. The following options can be considered: 1. **Replace with a wear-resistant material**: Use materials that are resistant to high temperatures and corrosion for manufacturing gears, such as special alloy steels designed for high-temperature and wear resistance. 2. **Check the pump’s maintenance and installation**: Ensure that the pump is maintained on schedule and is installed correctly, to avoid additional wear caused by installation issues. 3. **Consider using other types of pumps**: Given the issue of flow stability with the gear pump currently chosen, screw pumps or magnetically driven pumps could be considered; these pumps generally have a higher tolerance for solid particles and are easier to maintain. 4. **Increase monitoring frequency**: Regularly check the operation of the pump to identify issues early and make adjustments or replace components as necessary. It is recommended to consult a professional pump supplier to obtain more detailed advice and product specifications based on your specific usage conditions. .
