fatigue test for gauges

[mifeguerra]

I am selecting a high pressure low-volume cycling testing unit (fatigue) for pressure gauges ( up to 10,000 psi). The standard ASME B40.1 doesn't say much. I looked into a hydraulic pump but also considering pneumatic. The flow rate is very low < 1 lt/min. I supposely must do between 20 to 60 cycles/min ( the guge will be subjected to 15,000 cycles)

Has anybody done something like this?

Thanks in advance for helping me out.
