The Bosch Rexroth PVV52-1X/193-068RA15LLMC (R978933903) is a high-quality hydraulic vane pump with constant displacement, designed for efficient and reliable operation. This model features a robust construction where the rotor, running within a stator ring, engages with the drive shaft's tooth profile. The inclusion of vanes within the rotor slots allows for centrifugal force to press them against the stator ring's internal surfaces during rotation, creating displacer chambers that are sealed by control plates. This pump is engineered with a double-eccentric design of the stator ring that establishes two pressure chambers opposite two suction chambers, facilitating hydraulic unloading of the shaft which only needs to transmit torque. The design significantly reduces wear and enhances efficiency by unloading vanes in the suction range. Maintenance and repair are made convenient through an easily removable cover that provides access to the pump insert without needing to detach the housing from its carrier. The PVV52-1X/193-068RA15LLMC can be configured as a double pump by mounting two pump kits on a single shaft, sharing one suction port while providing separate oil outlets. The larger kit is always mounted flange-side with pressure ports in customizable positions for both kits. However, identical frame size kits cannot be paired as double pumps. This model boasts long bearing life due to its hydraulic shaft relief, low operating noise, easy serviceability due to exchangeable cartridges, and excellent efficiency. It can operate in both clockwise or counterclockwise directions and offers options for either cylindrical or splined drive shafts. Its very compact build makes it suitable for applications where space is at a premium but performance cannot be compromised. With its maximum operating pressure and displacement capabilities, this Bosch Rexroth vane pump stands out for its durability and versatility in various hydraulic applications.

Hydraulic pumps of type PVV 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.

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.

1)	Bold figure specifies the stage for which the flange (with double pumps) is intended.

The material numbers comprise the flange, the O-ring and the mounting screws.

Pipe thread "G" according to ISO 228/1

Comprehensive information and suggestions are contained in the Hydraulics Trainer, volume 3, RE 00281, “Project planning information and design of hydraulic systems".

When using vane pumps, we recommend particularly observing the information specified below.

Technical data

All specified Technical data depend on production tolerances and are valid at certain boundary conditions.

Please note that consequently, fluctuations are possible and that with certain boundary conditions (e.g. viscosity), the Technical data may also change.

Characteristic curves

When designing the drive motor, please observe the maximum application parameters possible shown by the presented characteristic curves.

Noise

The values for sound pressure level shown on page 8 have been measured based on DIN 45635, sheet 26. That means that only the sound emission of the pump is shown.

Environmental influences (place of installation, piping, etc.) have not been considered.

These values are in each case only valid for one pump.

With unfavorable influences at the place of installation of the power unit, the sound pressure level may, however, still be 5 to 10 db(A) higher than the values of the pump itself.

Drive

Electric motor + pump carrier + coupling + pump

Attention!

no radial and axial forces on the pump drive shaft admissible! Motor and pump must be exactly aligned! use a torsionally flexible coupling

Fluid tank

Adjust useful volume of the tank to the operating conditions.

Attention!

The admissible fluid temperature must not be exceeded use coolers, if necessary!

Lines and connections

Cut with an inclination of 45° Remove the protective plug at the pump We recommend using seamless precision steel pipes according to DIN 2391 and releasable pipe connections. Select the inner width of the pipes according to the connections Pipelines and fittings must be carefully cleaned before assembly. – min. distance 120 mm to the tank bottom Dirt deposits are not sucked in or raised min. 50 mm immersion depth, also with lowest fluid level admissible Foam formation is avoided Leakage and return fluid must not be directly sucked in again under any circumstances! Liquid temperature remains low For the inlet pressure refer to the Technical data

Recommendation for pipe-laying

Return fluid must not be directly sucked in again under any circumstances, i.e. select the largest distance possible between suction and return line Return flow outlet must always lie below the oil level Ensure suction-tight assembly of the pipelines

Filter

Use return flow or pressure filter if possible. (Suction filters only in connection with underpressure switch/clogging indicator).

Hydraulic fluid

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. In this connection, it is also necessary to clean the fluid tank from residues.

Commissioning

Check whether the system has been assembled carefully and properly. Only fill in hydraulic fluid through filters with the required minimum retention rate. Observe the arrow indicating the direction of rotation. Start up the pump without load and allow to pump at zero pressure for some seconds in order to allow for sufficient lubrication. Do not operate the pump without oil under any circumstances. If the pump does not deliver medium without bubbles after approx. 20 seconds, the system must be checked once again. After the operating values have been reached, check the pipe connections for leak-tightness. Check the operating temperature.

Bleeding

Before the initial commissioning, we recommend filling the housing and the suction line of the pump with oil. This increases the operational safety and prevents wear in case of unfavorable installation conditions. During the initial commissioning, the foaming oil has to be discharged in circulation at zero pressure by carefully opening the pressure flange (provide splashguard, if necessary). Only re-tighten the fitting applying the specified torque if bubble-free oil exits.

General information

The pumps delivered by us have been checked for function and performance. Changes of any kind at the pump are not admissible; otherwise, the warranty will become void! Repair works may only be carried out by the manufacturer or their authorized dealers and agencies. No warranty is accepted for independently performed repairs.

Notice!

Assembly, maintenance and repair of the pump may only be carried out by authorized, trained and instructed personnel. Pump may only be operated with the admissible data (see Technical data)! The pump may only be operated if it is in an unobjectionable condition. For all works at the pump, depressurize the system! Unauthorized modifications or changes which affect the safety and function are not admissible! Apply protective devices (e. g. coupling guard) and/or do not remove existing protective devices! Always ensure tight seat of all mounting screws! (Observe the specified tightening torque) The generally valid safety and accident prevention regulations must be imperatively complied with!

For limitation of the operating pressure or (and) for the solenoid-actuated unloading of the operating pressure, we recommend our pump safety blocks according to RE 25880 and RE 25890.
