Sulfuric acid is pumped from the tank truck to the storage tank; which type of pump is suitable for this purpose
Thread Content
As the title suggests: The pump is prone to damage during unloading, especially at the beginning and near the end of the pumping process, when there is a temporary shortage of liquid supply. Can damage be minimized by improving operational management? I’d like to hear everyone’s opinions.
A pneumatic pump can be used to prevent damage to the pump caused by vacuum pumping.
Agree with the person above; pneumatic pumps can operate without fluid, but fluoroplastic materials must be used
I agree with the views expressed by those above; it’s no problem to use pneumatic pumps for transferring methanol, propanol, and similar substances – just pay attention to the choice of material
Pneumatic diaphragm pump? What we unload is 98% concentrated sulfuric acid.
The hydrobromic acid that our unit unloaded was handled using dual-pneumatic diaphragms, and the system remained quite stable – it never broke down
What’s there to be afraid of? It’s just 98% sulfuric acid; there are many materials with higher corrosivity and toxicity than sulfuric acid that are transported using pneumatic pumps. The most important points are: 1, it is necessary to choose the right material; 2, any damage to the first membrane layer must be addressed promptly; 3, the pipeline connections during transportation must be secure. An automatic one-way valve can be used for connection
Then use a fluoroplastic-lined centrifugal pump
It’s not that I’m afraid of anything. I’m checking to confirm whether it’s a diaphragm pump, as there are other types of pumps that are driven by air pressure.
Fluoroplastic centrifugal pumps can suffer shaft burnout if proper care is not taken during operation. It’s better to have the person who delivers the material bring their own pump. To avoid all these troubles.
