Flow rate of pump
Flow rate of pump
(OP)
We are doing our PSM for the facility and the question came up about flow rates of our solvent pumps. All our pumps are rated below 80 gpm. This was done years ago and what I remember was that over 80 gpm will start to cause staic buildup in some of the solvents. My question is where can I find what the correct /safe flow rates for different solvents are.





RE: Flow rate of pump
If you look at the pumps alone as the first step, the (or any good) pump supplier could give the answer if any other or new construction has the limitation you mention.
For existing pumps and pipelines you need to consider both pumps and pipelines, start with the original pump manufacturor.
RE: Flow rate of pump
I don't know what static build-up is, but if the solvent is not Newtonian, then the flow rate will affect the viscosity of that solvent.
After you get the material specifications of the solvent, then it's a matter for a pipeline engineer

It gives a table with flow rates through schedule 40 pipe.
At 15ft/sec and 3ft/sec at what GPM not to exceed.
The 15 & 3 ft/sec flows are based upon the conductivity of the particular solvents being used.
Thanks again.
