WebbThe principal curves that define a pump’s operating characteristics are the performance curve (blue), the power curve (green), and the efficiency curve (red). The relationship between head and flowrate for a single pump is called its characteristic curve or performance curve ( Figure 2 ). WebbUsing the same formula, we estimate that the pumping speed of the Roots pump will be 61 l s -1 = 220 m³ h -1, and select an Okta 500 with a pumping speed $S_0$ = 490 m³ h -1 and an overflow valve pressure differential of $\Delta p_d$ …
