This reduces the instan- taneous rise and fall of the pressure. This does not show on a conventional flow bench due to the type of instrumentation being used. If an oscilloscope or very quick data acquisition system is used, you can see the pulses from the gears. Why a Tough Pump? This smoother wave cycle allows the relief valves to operate more consistently because the valves aren’t being hammered by the pressure variation. © 2024 Pump RPM PSI 200 300 350 400 450 500 700 800 900 1100 1300 1600 5 337 508 588 671 757 839 1170 1310 1574 1903 2241 GPM 0.97 1.46 1.71 1.93 2.18 2.41 3.36 3.76 4.52 5.47 6.44 50 324 489 552 654 744 820 1159 1301 1543 1877 2227 2775 GPM 0.93 1.40 1.59 1.88 2.14 2.36 3.33 3.79 4.43 5.39 6.40 7.97 100 312 479 539 637 724 804 1140 1286 1511 1846 2200 2750 GPM 0.90 1.38 1.56 1.83 2.08 2.31 3.28 3.76 4.34 5.31 6.32 7.90 150 306 467 534 627 709 794 1126 1273 1487 1815 2174 2725 GPM 0.74 1.34 1.54 1.80 2.04 2.29 3.23 3.73 4.27 5.22 6.20 7.83 100 549 843 949 1122 1275 1416 2007 2263 2660 3250 3873 4813 GPM 1.58 2.42 2.75 3.22 3.66 4.07 5.77 6.62 7.64 9.34 11.13 13.83 100 627 962 1084 1281 1456 1617 2292 2584 3038 3711 4423 5500 GPM 1.80 2.77 3.14 3.68 4.18 4.65 6.59 7.56 8.73 10.66 12.71 15.80 4000 3500 2000 2000 2000 2000 Pump Size (Gasoline .695 at 70 ° F specific gravity) Flows are in PPH (lb/hr) of Gasoline Series 1 Series 2 Kinsler Tough Pump Flows are at Pump Shaft RPM, --> NOT Engine RPM Kinsler Tough Pump 4/4/2024 Flows are at Pump Shaft RPM, --> NOT Engine RPM.
