***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth PVQ2-1X/068RA15UMB (R901002931) is a high-efficiency displacement pump specifically designed for mobile and industrial applications that operate in an open circuit. This robust double-stroke vane pump features axial gap compensation, which contributes to its reliable performance and longevity. Internally force compensated without hydraulic bearing load, the PVQ2-1X/068RA15UMB ensures a long service life with minimal wear.
Constructed with either aluminum or cast iron housing, this fixed displacement pump is equipped with NBR seals and designed for use with various hydraulic fluids including HLP, HLPD, HVLP, and HVLPD types. The pump operates at a maximum pressure and has a cylindrical shaft measuring .mm with a fitting key. It supports a speed range from minimum to maximum RPM, capable of delivering a maximum flow rate.
The design ensures clockwise rotation of the rotor within the stator ring, utilizing vanes that are pressed against the stator by centrifugal force during operation. The unique double-eccentric design of the stator ring creates pressure chambers that hydraulically unload the shaft, transmitting only torque while reducing wear. The innovative control plate design compensates for thermal expansion and reacts swiftly to pressure changes, maintaining high volumetric efficiency.
Servicing this model is streamlined due to its construction; by removing the cover, the entire pump insert can be quickly replaced without detaching the housing from its carrier. The PVQ2-1X/068RA15UMB's structural design makes it particularly well-suited for mobile applications where compactness and reliability are paramount.
Additionally, this model can be configured as part of a double pump setup by mounting two pump kits on one shaft—though kits of the same frame size cannot be combined—offering flexibility in system design. Each installation kit has separate oil outlets: one through the flange housing for the front kit and another through the cover for the back kit.
Overall, Bosch Rexroth's PVQ2-1X/068RA15UMB provides durable performance with low noise operation and excellent serviceability for demanding applications requiring reliable hydraulic power delivery.

Hydraulic pumps of type PVQ are vane pumps with constant displacement. The rotor (2) running in a stator ring (3) is located on the tooth profile of the drive shaft (1). The slots of the rotor accommodate the vanes (4) which are pressed against the internal surfaces of the stator ring by the centrifugal force upon rotation of the rotor. The displacer chambers are laterally sealed by the control plates (5). Due to the double-eccentric design of the stator ring, there are in each case two pressure chambers opposite of two suction chambers, which provides for hydraulic unloading of the shaft. So it only has to transmit the torque. The vanes are partially unloaded upon passage through the suction range. This unloading has a wear-reducing effect and ensures high efficiency. By simply removing the cover (6), the pump insert (consisting of rotor, vane, stator ring and control plates) can be removed without the need of removing the housing (7) from the pump carrier. This allows for fast maintenance and repair of the pump. Due to the structural design, type PVQ is particularly suitable for mobile applications. The special design of the control plates allows for compensation of the thermal expansion of the rotor and perfect counteraction to sudden pressure changes. Due to the division of the control plates into flexible discs (7) and cover plates (8), counter pressure chambers (9) are formed which are balanced against the pressure in the displacer. This ensures the perfect play between rotor and flexible discs and thus best volumetric efficiencies.
Double pumps are formed by installing two pump installation kits on one joint shaft. The oil inlet is realized by one joint suction port in the central housing (10). The oil outlet is realized separately by both pump installation kits. For the front pump installation kit, the pressure port is located in the flange housing, for the back pump installation kit in the cover. The larger pump installation kit is always located on the flange housing side. Pump installation kits of the same frame size cannot be used as double pumps.

Please observe our provisions according to catalog sheet RE 07075. We recommend brand hydraulic fluids. Different hydraulic fluid types must not be mixed as this might result in degradation and deterioration of the lubricity. According to the operating conditions, the liquid must be renewed at certain time intervals.
