Question: What kind of pump is generally used to transport acidic mortar?
Thread Content
Medium conditions: Solid content of 30-40%, particle size
Screw pumps with rubber linings could be considered
Recommended pumps specifically for Y L series filters (leak-free): http://www.jsyamei.com/product/pump_yl.htm
It falls under the category of slurry pumps. There are many manufacturers of pumps specifically designed for filter presses in China; it is recommended to search on Baidu.
Are there any successful cases for 2# mantoman?
It can be pumped using the fluoroplastic mortar pump developed by our company, which ensures that the required standards are met. There are many successful cases; for example, a customer in Quzhou, Zhejiang, has used it. It would be best to provide information on flow rate and head pressure
The lined screw pumps produced by Lanzhou Naichi Pump Industry should work fine; the original poster can get in touch with that manufacturer, and they will help with the selection.
Screw pumps can be used, Lxn_663; the higher the solid content, the more likely a screw pump will be employed.
Solid particles can be transported using a screw pump. So, isn’t the stator rubber severely worn out? It has less contact with the screw pump; I still can’t figure it out. Please provide more details. I know screw pumps are used to transport a large amount of sludge.
At the beginning, screw pumps were mainly used to drive filter presses in wastewater treatment, but they were gradually phased out over time. More and more people started using diaphragm pumps instead. In my opinion, screw pumps can handle materials containing particles without any problems; however, after prolonged use, the stator suffers significant wear, which reduces efficiency. The main reason is that when the filter press is compressing sludge, the system resistance increases, leading to a rise in liquid temperature and making it easier for mechanical seals to get damaged. Diaphragm pumps, on the other hand, stop automatically when the system resistance becomes too high. Hehe, it’s just my personal opinion.
As long as it is a fluid being transported, the movement of solid particles in the liquid inevitably causes wear on the equipment; the stator can be made of other materials, not necessarily rubber. The poster is referring to a sulfuric acid suspension; frankly, this is a very problematic situation. The wear caused by solids on the surface accelerates the acidic corrosion. It’s best to consult the relevant manufacturers, as they have more experience in this area.
