Functional diagram
Hydraulic pumps of type PVH 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.

General project planning notes
Intended use
Vane pumps are intended for the assembly of hydraulic drive systems in machine and system construction.
Technical data
The system or machine manufacturer must ensure compliance with the permissible technical data and operating conditions. The pump itself does not contain a device to prevent operation outside the permissible data. It is possible to operate the pump outside of the permissible technical data to a certain extent; the express written consent from Bosch Rexroth is, however, required. All specified technical performance features are median values and apply with the specified general conditions. In case of modifications to the general conditions (e.g., viscosity), the technical data may change as well. Scatter corresponding to the relevant state of technology is possible.
Hydraulic project planning
Air bleeding option for commissioning
For Rexroth PVH vane pumps, a manual or switchable air bleeding option for the initial commissioning or any recommissioning after maintenance and repair work is to be provided. The air bleeding point is to be set in the pressure line before the first valve or check valve. Air bleeding may be performed with a maximum counter pressure of 0,2 bar.
Examples of air bleeding circuits
Switchable bleeding
Manually operated bleeding
Suction line
The line cross sections are to be dimensioned for the specified flows such that an ideal suction speed of 0,6 to 0,6 m/s is achieved on average. The suction speed should not exceed a maximum value of 2 m/s.
The suction cross sections at the pump itself are designed for the maximum flow and therefore serve only as reference. In case of continuous operation at rotational speeds lower than the permissible maximum speed, the suction tube diameter is also to be dimensioned smaller than the suction port of the pump depending on the actual suction speed.
Overall, the suction line is to be designed so that the permissible inlet working pressure is maintained. Bends and a combination of suction pipes from several pumps are to be avoided. If the use of a suction filter is unavoidable, it must be ensured on the system side that the lowest permissible inlet working pressure is not exceeded even if the filter is contaminated.
Ensure the air tightness of the transitions and the pressure resistance of the suction hose with respect to the external air pressure.
The immersion depth of the suction pipe should be selected as large as possible (at least 100 mm at the lowest fluid level). Depending on the internal reservoir pressure, the viscosity of the operating medium and the flow conditions within the reservoir, no vortex may form even at maximum flow. There is otherwise a risk of air being drawn in. Return fluid and case drain fluid must not be immediately be drawn in again.
Dimensions in mm
Pressure line
Sufficient burst resistance of the pipes, hoses and connecting elements must be ensured for pressure lines. The cross sections should be based on the maximum flow in order to avoid additional excessive loading of the pump due to back-pressure. Here, you must also take into account the pipe losses over the entire pressure line length and other line resistances (e.g., bends, pressure filters).
Pressure safeguarding
The PVH vane pump does not include any devices for adherence to the maximum working pressure. The setting and safeguarding of the permissible working pressure must be ensured on the system side.
The pressure-relief valves necessary for this purpose are to be designed with consideration given to the maximum flow and the rate of pressure increase that will occur such that the permissible intermittent working pressure is not exceeded.
Mechanical project planning
Fastening
The screws must be accessible on the machine-side so that the required tightening torque can be applied. The tightening torque of the screws is based on the operating conditions and involved elements of the screw connection and must be specified by the manufacturer in the power unit, machine or system project planning.
Tank
In the tank construction or the selection of suitable standard tanks, the following requirements are to be observed:
Selection of the largest tank volume possible, dependent on the permanent or average flow, in order to allow for the separation of air bubbles by means of sufficient duration time of the medium in the tank. The air release capacity of the hydraulic fluid used is also of importance. Provision of settling zones for the hydraulic fluid in the tank in order to allow for air release. Provision of guiding plates in order to allowing for the deposit of contamination at the tank bottom outside the pump suction area. Large dimensioning of the tank surfaces dependent on the heat output to be dissipated via the tank walls.Required power unit functions
Hydraulic power units should at least be equipped with the following features:
Tanks, where internal pressure corresponds to the ambient pressure in accordance with the design, must be equipped with breathing filters for pressure compensation purposes. The hydraulic fluid should only be filled in using filling connections excluding filling with unfiltered fluid. The ingress of contamination or humidity must be avoided. In case of use in highly contaminated environments, the tank must to this end be pre-tensioned by means of air pressure. If cleansing of the external tank side is intended or to be expected during the period of use, select tank fittings for pipes, lines, or hoses, which ensure safe sealing against external pressurization with water jet.Place of installation and environmental conditions
With places of installation from a geodetic height of more than 1000 m, the pump is to be arranged in or below the tank or the tank is to be pre-tensioned by means of compressed air in order to comply with the admissible minimum inlet pressure. A short suction line with large cross-section must be selected, bends should not be used.
When installing the pump more than 10 m below the tank, the reduction of the inlet pressure to the maximum admissible value must be ensured by means of additional measures.
When operating the pump in salt-containing or corrosive environments or when pressure loading with strongly abrasive substances is possible, make sure on the system side that the shaft seal ring and the sealing area of the shaft do not make direct contact with the environment.

Maintenance schedule and operational safety
For safe operation and a long service life of the pump, a maintenance schedule must be prepared for the power unit, the machine, or the system. The maintenance schedule must ensure that the specified or permissible operating conditions of the pump are complied with over the entire period of use.
In particular, compliance with the following operating parameters has to be ensured:
The required oil cleanliness The operating temperature range The filling level of the operating mediumFurthermore, the pump and the system are to be checked for changes to the following parameters on a regular basis:
Vibrations Noise Temperature difference between pump – fluid in the reservoir Foaming in the reservoir Leak-proofnessChanges to these parameters indicate component wear (e.g., drive motor, coupling, pump, etc.). The cause has to be determined and remedied immediately. In order to achieve high operational safety of the pump in the machine or system, we recommend checking the aforementioned parameters continuously and automatically and the automatic shut-down in case of changes exceeding the usual fluctuations in the specified operating range.
Plastic components of drive couplings should be replaced regularly, though after no more than 5 years. The corresponding manufacturer's specifications are paramount. For preventive maintenance of the pump, we recommend having the seals replaced after an operating period of no more than 5 years by an authorized Bosch Rexroth service company.
Pump safety block
For limiting the working pressure and for the pump circulation at zero pressure, we recommend our pump safety blocks. Automatic air bleeding during commissioning is, however, not possible via DBA blocks. In this case, we recommend separate, manual air bleeding.
