Pumping Bleach&NaOH
Pumping Bleach&NaOH
(OP)
Hi all...
I am working on a project to size a pump for for the following application parameters:
Flow=120GPM
Head=120
Temp=120F
Press=atmospheric
here is the interesting thing: The fluid to be pumped is 10%vol. Caustic soda and 15%vol. Bleach. Is Specific Gravity of 1.2 conservatively good?
Now that I have to select the pump material, is 316SS good for this application?
I am new with the company and my supervisor has business background, so, he left me to decide what is good for this application.
Any comments on my unexperienced conclusions?
Thanks in advance:

What ever you find that works with bleach will probably work with caustic.

In our experience the vulnerable part will be the mechanical seal rather than the body material in a metallic pump.

Use non-metallics. I wouldn't used coated parts but solid polymers. With caustic you can't use glass reinforcement. Use other forms of loading to get the strength that you need.
For other parts use Ti and ceramic.
You may be using FRP piping. Be aware that if there is damage or failure of the inner resin layer you will start attacking the glass fibers and rapid deterioration may follow.
