Hydraulic pump

A hydraulic pump to provide fluid to a hydraulic tool to perform an operation on a workpiece, the hydraulic pump comprising:

• a work port that supplies fluid to the hydraulic tool;
• a high-flow piston that supplies fluid along a first flow path to the work port;
• a plurality of high-pressure pistons that supply fluid along a second flow path to the work port;
• an unloading valve positioned along the first flow path, the unloading valve actuating from an open state to a closed state when a pressure level of fluid in the second flow path exceeds a first threshold pressure;
• and
• a controller to allow a user to select a mode of operation, the controller setting a second threshold pressure of the hydraulic pump based on the mode of operation, the second threshold pressure corresponding to an end operation of the hydraulic tool.
