Tocalculate approximate horsepower for the other conditions,use the following formula:[ ]HP = Q x (PSI) + (CHp)1714Actual GPM is directly proportional to drive speed and maximumvolume setting. Flow loss, however, is a function of pressureonly.WHERE:Q = Actual Output Flow in GPMPSI = Pressure At Pump OutletCHp = Input Horsepower @ Full Compensation @ 1800RPM (from graph read at operating pressure)LPM GPM106.0 28.0Flow vs. SpeedPVP 23/33Inlet Characteristics at Full DisplacementInlet PressureVacuumbar.41.28.14PSI642bar In-Hg0 0.17.34.5151015(Graph only valid at sea level)RecommendedOperating ConditionDO NOT OPERATEIN THIS REGIONOutlet Flow @ Max.
