Hydraulic pump applications sometimes require the pump to be able to provide relatively low pressure with larger amounts of fluid moved, while other applications call for relatively higher pressures but less fluid moved. The multi-speed hydraulic pump can operate at multiple speeds so as to provide multiple outputs of pressure and flow. In a two-mode version, the pump has one mode of operation that provides for lower pressure/more fluid moved and another mode of operation that provides for higher pressure/less fluid moved. Having multiple modes of operation in the pump allows for a single pump to provide greater movement or greater pressure while working within the limits of the force or speed at which the pump is actuated.
