Corrosive handling pump choices
Corrosive handling pump choices
(OP)
My problem is frequent pump wear due to corrosion. Would someone be able to provide advise on the pump type options needed to move caustic (na persulfate in Naoh as an example, oxidizes or reducing agents) with pH >10. I need a flow rate between 3 and 10 gpm. I need to pump the liquid <300 feet with minimal change in elevation (<30 feet). It is essentially a spray system similar to pesticide application but capable of handling more corrosive liquid. The pumped liquid would be at temps near 85celcius. Distance is important to operate in explosive atmosphere. End use flushing is routine but Perhaps there is a pump that is simple enough to repair internal components as needed.
The design includes a system mounted on a trailer. Fresh water tank with water heater, mixing tank for caustic sol'n, pump and hose reel with spray wand.
Thanks for any tips...

RE: Corrosive handling pump choices
If you're not using copper/zinc then your corrosion is more likely to be due to the oxidising agents. What sort of corrosion are you seeing and what are you flushing with at the end?
As a chem eng/metallurgist the first part of any answer I give starts with "It Depends"
