  • What is the difference between pressure and head?

    2016-5-31 · The pump selection of a pump is driven by the following main parameters: – Head (H) – Flow rate (Q) – Fluid characteristics (ρ, γ, T ….) Sometimes head can be confused with pressure during pump choice. As a matter of fact there is a strict relation between them which is defined by the fluid specific gravity, so the relation is fluid dependent.
