Technical Data Sheet Orenco <br /> e W AT E R <br /> Using a Pump Curve <br /> A pump curve helps you determine the best pump for your system.Pump curves show the relationship between flow(gpm or Usec)and pressure <br /> (total dynamic head or TDIO,providing a graphical representation of a pump's optimal performance range.Pumps perform best at their nominal <br /> flow rate-the value,measured in gpm,expressed by the first two numerals in an Orenco pump's product code.The graphs on the following <br /> page use solid lines to show the optimal pump operation range.Dashed lines indicate flow rates outside of the optimal range for each pump.For <br /> the most accurate pump specifications,use Orenco's PumpSelect114 software. <br /> Pump Curves <br /> Flow in liters per second(!,/sec) Flow in liters per second(L/sec) <br /> 0.13 0.25 0.38 0.50 0.63 0.76 0.88 1.00 0.32 0.63 0.95 1.26 1.58 <br /> 270 1 1 i I i , i 240 1 1 i I <br /> P-Series,60Hz, P-Series,60Hz, <br /> 240 0.5hp 10gpm pump 73.2 4 0.5hp 20gpm pump co <br /> m <br /> p 210 P100511 64.0TS 2 200 • I P200511 j 61.0 m <br /> E E <br /> p180 54.9Z p160 48.8= <br /> p i. p <br /> to 45.7-- 1120 <br /> 36.6120 36.6.e .GI c <br /> v <br /> M 90 :r:! <br /> M.
