When and How to Adjust a Load-sensing Hydraulic PumpVariable-displacement pumps are used in hydraulic systems where the flow requirements vary. This usually means the system has several actuators and, 

The Basics of Variable-Displacement Pump Controls - Fluid Nov 14, 2016 — The amount of flow that each pump can provide is dependent on a rotating group of pistons. By varying the stroke of the pistons, we adjust the Pressure Compensated Hydraulic Pumps - Womack Machine Radial piston pumps can sometimes be built with variable displacement but do PSI higher than the pressure adjustment of the compensator piston spring to
