Section TECH-A Centrifugal Pump Fundamentals

A centrifugal pump imparts velocity to a liquid. This velocity energy is then transformed largely into pressure energy as the liquid leaves the pump. Therefore, the head developed is approximately equal to the velocity energy at the periphery of the impeller This relationship is expressed by the following well-known formula: H = v2 2g

The head is constant, even if the density (and therefore pressure) changes. The head of a pump can be expressed in metric units as: h = (p2 - p1) / (ρ g) + v22 / (2 g) (1) where h = total head developed (m) p2 = pressure at outlet (N/m2) p1 = pressure at inlet (N/m2) ρ = density (kg/m3) g = acceleration of gravity (9.81) m/s2
