When its a peristaltic pump the rate should depend on primary pressure. Rossi has the water container below the pump and this creates subpressure and should reduce the rate. The secondary pressure should not influence the rate too much, as long as the hose doesnt leak, because all water that was sucked in must be finally pressed out. Of course the strength of the motor has also influence. I think these pumps are calibrated for zero input pressure. The rate also depends on the hoses and their wear.
