Which submersible sewage pump is resistant to salt corrosion?
Thread Content
May I ask, which material of submersible sewage pumps is more resistant to salt corrosion? A submersible pump is intended to pump wastewater containing 5 g/L of sodium chloride. How long can an iron-cast pump last, and how long can 304 and 316 stainless steel pumps last? Those who have had similar experiences, please share your insights. Suggestions and brand names of pumps are also welcome. Thank you.
Why not use a surface pump? Fluorinated liner centrifugal pumps are safe and reliable.
With a water depth of 5.5 meters, the price of above-surface pumps must be quite high, right?
In terms of price, submersible pumps are cheaper, but if performance is important, then self-priming pumps are the better choice; a fluorocarbon-lined self-priming pump will suffice. . .
Land-based pumps are not allowed to be used; only submersible pumps can be employed. :L
If specified, pick it up after each use and wash it with clean water.
Since the wastewater is salty, the submersible pump remains submerged in it, making any cleaning efforts pointless. :Q
Due to the high salt content and the need for corrosion resistance, it is recommended to use fluoroplastic pumps.
Are there fluoroplastic pumps that are submersible pumps? Could you provide the manufacturers?
Is a submersible pump really necessary? Submersible pumps should be good too; there are many manufacturers of this type of pump.
Only submersible sewage pumps can be used; submersible pumps are not suitable. :dizzy:
