The Bosch Rexroth PVV51-1X/193-036RB15DDVC (R978915221) is a high-performance hydraulic vane pump with a constant displacement design, ensuring efficient operation across various applications. It features a robust construction where the rotor runs in a stator ring on the drive shaft's tooth profile, with vanes housed within the rotor slots. These vanes are pressed against the stator ring's internal surfaces by centrifugal force during rotation, creating displacer chambers that are sealed by control plates. The innovative double-eccentric design of the stator ring allows for two pressure chambers opposite two suction chambers, facilitating hydraulic unloading of the shaft which only needs to transmit torque. This model boasts low wear characteristics due to hydraulically unloaded vanes during suction range passage, significantly reducing wear and enhancing service life. The design also contributes to low operating noise levels and excellent efficiency. For maintenance convenience, the pump insert—comprising rotor, vane, stator ring, and control plates—can be swiftly removed after detaching the cover without dismounting the entire housing from its carrier. As a double pump configuration, it incorporates two pump installation kits on a shared shaft with a common suction port in the central housing while maintaining separate oil outlets for each kit. The larger of the two kits is mounted on the flange housing side; however, kits of identical frame sizes cannot be configured as double pumps. The PVV51-1X/193-036RB15DDVC offers flexibility in serviceability with easily exchangeable pump cartridges and customizable pressure port positions. It can operate with both clockwise and counterclockwise rotation directions and accommodates either cylindrical or splined drive shafts. This model is recognized for its compact build and very good efficiency while providing consistent performance under maximum operating pressures and displacements specific to its frame size and component series.
