Proposed Hydraulic Pump Testing for Hydraulic Fluid Qualification


The current ASTM D-2882 hydraulic vane pump test does not provide the necessary correlation required for the prediction of the lubricating properties of a hydraulic fluid in various piston pump operations. All too often, a fluid will exhibit excellent wear properties in the Vickers V-104 vane pump used in the ASTM D-2882 test, yet produce catastrophic failure at various wear interfaces in a piston pump which may consist of different material pairs, contact loading, configuration or speed. In this paper, a new piston pump test, which is conducted under cycled pressure testing conditions, is proposed. The new test will provide an excellent assessment of the lubricating properties of a hydraulic fluid under a wide variety of wear conditions.
