Abstract
Analyzes a flow pulsation of parallel gear pump with 3-idlers,derives formulae for calculating displacement,average flow velocity,instantaneous flow and pulsation flow rata.It is pointed out that this sort of gear pump can provide higher flow pulsation frequency when taking teeth number z=3K±1.
