Radial piston pump disturbing frequency

Relatively simple question, but not one I can find an answer for. For a radial piston pump, what should I term the frequency seen on an FFT equal to all pistons having moved? This would be analogous to the vane passing frequency for a vane pump. I don't want to call it the piston rate, because that could get confused with the rate of a single piston - much like cylinder firing rate/engine firing rate for diesels.

I use "Piston Pass Frequency".

Using a throw back to an internal combustion engine, perhaps somehow introduce the term "rate".  For example the "firing rate" of a 2-stroke or 4-stroke diesel.  With the diesel of course the number differs 2-stroke vs. 4-stroke, but it is still a "rate" of occurrence of the firing rate.
