*Displacement (flow) values represented refer to "theoretical" flow, neglecting inefficiency resulting compressibility of water and expansion of pressure-bearing components. Specified maximum flow rates are based on selected input powers and working pressures and constrained by power end limitations (pump speed, frame load, maximum input power). Actual output may vary depending on the performance specifications of the engine (or motor), drive sheave ratio, and actual working pressure.
