Pump type suggestion
Pump type suggestion
(OP)
Hi all,
I have an application for boiler refeed that we are designing and require a small booster pump. We have high TDS (not exactly sure what the number is as yet though as it is going through a settling tank), and a high solids content. The fluid is water, the temperature is 85C (185F) and the flow requirement is 5gpm (30m3/day). Pi = 15 psi, Pout = 200 psi.
I am considering a PC pump to move the fluid, but am modestly concerned about the temperature. The client does not want to lose the heat content of the fluid, so any cooling is out. We have considered a centrifugal pump, but discarded that idea because of the solids content. So...
Is a PC pump applicable for this procedure?
Thanks in advance for your attention.

As a chem eng/metallurgist the first part of any answer I give starts with "It Depends"

If you can tell us what TSS (and/or TDS) consists of (concentration, hardness, reactivity etc), you might have a chance of someone being able to give you a better answer.

If a vendor says it is OK at the temperature on the data sheet then I can't see any reason to doubt him. 5GPM is relatively low flow but make sure you have enough length on your skid - they are very long things.
My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way
