Pumping Liquid Refrigerant- what will work?
So im working on a new project, and trying to pump liquid refrigerant(134A) with a Delta P of 375 PSI, up to 510 +- Flow rate will be between 14-18 GPM. I am having a difficult time tracking down a pump. At first thoughts, i was looking for a gear pump, but people advised me that would not be the best. I received a quote on a Regen turbine pump for 16K USD. That is way too much for this project. I know vane pumps are used regularly at lower pressures, but i believe that may be the best for my application, if one can accommodate high pressures.
Any thoughts you may have are appreciated.
