A variable displacement pump is a type of hydraulic pump that can adjust its output flow rate and pressure based on the demands of the system it serves. Unlike a fixed displacement pump, which has a constant flow output regardless of the load, a variable displacement pump can change its displacement (the amount of fluid it displaces per revolution) to match the requirements of the hydraulic system.
