Flow loss, however, is a function of pressureonly.<strong>PVP</strong> 41/48Inlet Characteristics at Full DisplacementInlet PressureVacuum79.568.160.645.434.122.711.4bar.55.41.27PSI864.14 2bar In-Hg0 0.34.681.03211816129630BarPSI05101500LPM GPM90.9 2479.568.160.645.434.122.711.4211816129630BarPSI000Flow691000EfficiencyFull Flow PowerCompensated Power1382000Pressure(Graph only valid at sea level)RecommendedOperating Condition2073000<strong>PVP</strong>48 @ 1200 RPMFlow691000EfficiencyFull Flow PowerCompensated Power13820002073000[ ]HP = Q x (PSI) + (CHp)1714DO NOT OPERATEIN THIS REGION33.622.411.202754000KW44.833.622.411.20275400045.030.015.00HP60.045.030.015.00PowerPowerPressureWHERE:Q = Actual Output Flow in GPMPSI = Pressure At Pump OutletCHp = Input Horsepower @ Full compensation@ 1800 RPM (from graph read atoperating pressure)<strong>PVP</strong> 41/48Flow vs. Shaft Speed1.38 200 00 1000 2000 3000 0 1000 2000 3000hpm102-1.p65, lw, jkShaft Speed - RPMShaft Speed - RPMEfficiency - %Efficiency - %90807060501009080706050Outlet Flow @ Max.
