The Bosch Rexroth PVQ21-1X/055-027LJ15DDMB (R987109917) is a high-performance hydraulic vane pump with a constant displacement design, optimized for mobile applications. This model features a robust construction with a rotor running in a stator ring, accommodating vanes that are pressed against the stator ring's internal surfaces to create efficient displacement chambers. The double-eccentric design of the stator ring establishes two pressure chambers opposite two suction chambers, ensuring hydraulic unloading of the shaft and transmitting only torque, thereby enhancing the pump's longevity and efficiency. The innovative control plates in this pump compensate for thermal expansion and respond effectively to sudden pressure changes, maintaining optimal volumetric efficiencies. The flexible discs and cover plates create counter-pressure chambers that balance against the displacer's pressure. This precise interplay between components results in low wear and reduced operating noise. Maintenance and repair are made convenient with this model, as the pump insert can be easily removed without detaching the housing from its carrier. The PVQ21-1X/055-027LJ15DDMB also permits easy configuration of pressure ports and accommodates both clockwise and counterclockwise rotation directions. Drive shaft options include cylindrical or splined variants. For applications requiring higher flow rates, this unit can be configured into a double pump setup by mounting two pump kits on a single shaft, with separate oil outlets for each kit. However, it is essential to note that only different frame sizes can be combined; identical frame sizes cannot be used as double pumps. Key specifications include long bearing life due to hydraulic relief of the shaft, exchangeable pump cartridges for straightforward servicing, high efficiency, very compact build for space-saving installations, and selectable position of the pressure ports for each installation kit.
