The Oxygenics shower head flows 2.0 GPM at 80 PSI. Lower pressures result in lower flow rates.

Your onboard pump will not supply anywhere near 80 PSI. This graph is for the Shur Flo 4008, a common pump. Note that as pressure rises, flow rate decreases.

Bottom line is I would be surprised if your actual flow rate when running off the onboard pump was even half of the shower head's rated 2.0 GPM.
