Frequent failure issues with FY submersible pumps
Thread Content
Our plant’s submersible pumps are failing frequently. Can we use other pumps as alternatives, such as self-priming pumps? Are there any colleagues who have successful experience with this? I’m begging for advice!
What medium is being transported, and what are the specific operating conditions?
You can add me on WeChat at 13780933572; I can provide the detailed specifications as well as the self-priming height
Of course, a self-priming pump can be used as a substitute; we have many application examples. Contact me via my signature
First, we need to look at the reasons for the frequent failures
I mainly need to check whether your medium is flammable; in our unit’s submersible pumps, oil and gas leak out along the axis. So the cam rotor pump that we modified after design is not yet in use, but it should work very well. You can give it a try
Methanol, water; temperature at room temperature, with a maximum temperature of around 60 degrees; depth under liquid nearly 3.5 meters
A self-priming pump can be used as a substitute; feel free to contact me for the specifications.
It can self-priming; with strict environmental regulations nowadays, submersible pumps are prone to leaking oil and gas
It’s probably because methanol has a low density, which causes cavitation in your submersible pump and leads to ongoing problems with it
Install a high-position vacuum water tank, with water entering from the top and exiting from the bottom, to be used as a bottom valve for water
