The Bosch Rexroth PVQ21-1X/068-046RJ15LDMB (R901255119) is a high-quality hydraulic vane pump with constant displacement, designed for robust performance and efficient operation. The PVQ21-1X/068-046RJ15LDMB features a rotor running within a stator ring on the tooth profile of the drive shaft, with vanes housed in the rotor slots. These vanes are pressed against the stator ring's inner surfaces by centrifugal force during rotation, creating displacer chambers sealed by control plates. This pump benefits from a double-eccentric stator ring design that establishes two pressure chambers opposite two suction chambers, enabling hydraulic unloading of the shaft which only needs to transmit torque. The innovative design facilitates wear reduction and promotes high efficiency by partially unloading the vanes in the suction range. Maintenance and repair are streamlined as the pump insert—comprising rotor, vane, stator ring, and control plates—can be easily removed without detaching the housing from its carrier. Particularly suited to mobile applications due to its structural design, this model compensates for rotor thermal expansion and effectively responds to sudden pressure changes through specialized control plates. These plates divide into flexible discs and cover plates, forming balanced counter pressure chambers that ensure optimal rotor play and volumetric efficiency. As a double pump configuration, it features two 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 kit is positioned on the flange housing side and cannot be combined with another of the same frame size to form double pumps. The Bosch Rexroth PVQ21-1X/068-046RJ15LDMB offers long bearing life due to its hydraulic shaft relief and reduced wear from hydraulically unloaded vanes. It operates quietly, is easy to service thanks to exchangeable cartridges, provides good efficiency, and allows flexible positioning of pressure ports. It can be driven clockwise or counterclockwise with either cylindrical or splined drive shaft options. Its compact build makes it an excellent choice for space-constrained applications where separate pressure port positioning is advantageous.
