H2SO4 Plant pumps
H2SO4 Plant pumps
(OP)
All,
I need to source some new pumps used to pump liquid sulphur at 130 - 145C. Can you suggest any specialist suppliers for this type of equipment.
Also, 96 to 99% H2SO4 at temps up to 90C.
Are submerged pumps the best way to handle these types materials. I have found Lewis pumps, are ther any others.
Recommendations appreciated

If you get away from pumps specifically designed for those services, then you can expect to quadruple your engineering involvement in the details of the pump designs being furnished.

You could talk to Monsanto Enviro-Chem about other manufacturers - they design sulfuric acid plants. They are in St. Louis at 314 275 5700 or www.enviro-chem.com
RE: H2SO4 Plant pumps
The pumps for hot (90C) sulfuric acid are going to be metallic and expensive. Premium, expensive materials such as Carpenter's "Alloy 20" or titanium may be required.
Is there a way to cool the sulfuric acid to ambient temperature, or must the heat be conserved ?
NACE has a guideline for handling Sulfric acid at ambient temperature.... it is:
"RP0391 - Materials for the Handling and Storage of Concentrated (90 to 100%) Sulfuric Acid at Ambient Temperatures"
I would ask a bulk chemical supplier about his recommendations on hot H2SO4 materials
Check this link for a Krupp alloy that seems to withstand your design conditions....

Please post again to let us know about what you have learned and what your decision is....
Good Luck....
