Abstract
A test device and a process for determining the accuracy of positive displacement gear pumps includes hydraulic cylinders which are fluidly connected to the output fluid flow(s) from a test pump. Each outlet flow is directed to a separate hydraulic cylinder. The test pump is driven by a motor for a preset number of revolutions. The length of stroke of the piston in each hydraulic cylinder is then determined, which corresponds to the volume of fluid provided from each pump outlet during the revolution of the gears in the pump. It can then be determined if the volumetric accuracy and efficiency of the pump is within acceptable limits.
