Using a Pump Curve <br />A pump curve helps you determine the best pump for your system. Pump curves show the relationship between flow and pressure (total dynamic <br />head, or TDH), providing a graphical representation of a pump's optimal performance range. Pumps perform best at their nominal flow rate. These <br />graphs show optimal pump operation ranges with a solid line and show flow rates outside of these ranges with a dashed line. For the most accurate <br />pump specification, use Orenco's PumpSelect`" software. <br />Pump Curves <br />800 <br />700 <br />w <br />as <br />c 600 <br />500 <br />Its <br />400 <br />CE 300 <br />200 <br />w <br />F� <br />100 <br />400 <br />350 <br />w <br />as <br />e 300 <br />250 <br />200 <br />v <br />150 <br />100 <br />w <br />1° <br />50 <br />�•.., - PF10 Series, 60 Hz, 0.5 - 2.0 hp <br />PF1005-FC <br />W/1/4" flow <br />controller <br />7— <br />0 2 4 6 8 10 12 14 16 <br />Flow in gallons per minute (gpm) <br />PF20 Series, 60 Hz, 0.5 -1.5 hp <br />0 5 10 15 20 25 30 35 40 <br />Flow in gallons per minute (gpm) <br />160 <br />140 <br />w <br />as <br />e 120 <br />100 <br />�n <br />= 80 <br />60 <br />40 <br />20 <br />a <br />0L <br />0 <br />?/A7 <br />PF15 Series, 60 Hz, 0.3 hp <br />3 6 9 12 15 18 21 24 <br />Flow in gallons per minute (gpm) <br />�0 5 10 15 20 25 30 35 40 45 <br />Flow in gallons per minute (gpm) <br />NTD-PU-PF-1 Orenco Systems* Inc. , 814 Airway Ave., Sutherlin, OR 97479 USA • 800-348-9843 • 541-459-4449 • www.orenco.com <br />Rev. 5.0, m 03/17 <br />Page 4 of 5 <br />
