Abstract: A hydraulic fracturing system with pump failure detection includes an engine, transmission, hydraulic fracturing pump and a driveshaft coupled between the transmission and the hydraulic fracturing pump to transfer torque from the engine to the hydraulic fracturing pump. A torque sensor is positioned and configured to measure torque acting on the driveshaft, with the torque sensor generating torque measurement data. A controller is programmed to analyze the torque measurement data and identify a pump failure mode based on the torque measurement data.
