Due to the varying engine speeds and fluctuating loads in the hydraulic and fuel systems, aviation piston pumps must also operate across a wide range of rotational speeds and load flow rate conditions. The pressure, flow rate, temperature, and vibration signals at different ports of a piston pump are critical indicators reflecting its operational health. Utilizing these limited metrics for fault diagnosis of piston pumps under multiple working conditions is a research field of significant importance and considerable challenge. Based on the operational characteristics of aviation piston pumps, this paper designs a feasible standardized test procedure and introduces a dataset comprising four types of signals—pressure, flow rate, temperature, and vibration—collected during the standardized tests. The dataset includes test data from the standard pump under normal conditions, as well as data collected under three typical fault conditions: wear of the servo piston, wear of the regulation valve, and wear of the swashplate bearing bush. Based on this dataset, researchers can validate the effectiveness of proposed fault diagnosis and health evaluation methods.  \n© 2025 The Author(s). Published by Elsevier Inc.
