The Bosch Rexroth PV7-1X/06-14RA01MA0-07 (R900919237) is a high-quality variable displacement pump designed for industrial applications that require reliable hydraulic power within an open circuit system. This pump is characterized by its exceptional efficiency, low noise production, and minimal pulsation levels, contributing to smooth and stable operations. The quick response behavior of the controller ensures precise control over the hydraulic flow, adapting swiftly to changing load demands.
With a maximum pressure capacity and a specific size in cubic centimeters (ccm), the PV7-1X/06-14RA01MA0-07 is engineered for performance and durability. It operates at a minimum speed with the capability to reach a maximum rotational speed, delivering a maximum flow rate as per its design specifications. The direction of rotation for this pump is clockwise without through-drive options.
Constructed with NBR seals, it can handle various hydraulic fluids such as HLP, HLPD, HVLP, and HVLPD types. The unit's weight reflects its robust build quality suitable for continuous industrial use. Notably, this rotary vane variable displacement pump comes without additional through-drive capabilities.
The internal mechanism comprises housing, cover, rotor, vanes, stator ring, compression spring, set screw, and control plate – all designed to facilitate efficient suction and displacement of hydraulic fluid. The pressure control feature allows for precise setting of the maximum operating pressure via an adjustable set screw that works in conjunction with the spring force.

Hydraulic pumps of type PV7...A are direct operated vane pumps with adjustable displacement.
They basically comprise of housing (1), cover (2), rotor (3), vanes (4), stator ring (5), compression spring (6), set screw (7) and control plate (8).
For limitation of the maximum flow, the pump is equipped with a set screw (9).
The driven rotor (3) rotates within the stator ring (5). The centrifugal force presses the vanes (4) guided in the rotor (3) against the internal sliding surfaces of the stator ring (5).
Suction and displacement procedure
The cells (10) necessary to transport the hydraulic fluid are formed by the vanes (4), the rotor (3), the stator (5), the control plate (8) and the cover (2).
The cell volume increases by the rotation of the rotor (3) and via the suction channel (S), the cells (10) are filled with hydraulic fluid. When the largest cell volume is achieved, the cells (10) are separated from the suction side.
If the rotor (3) is rotated further, connection to the pressure side is established, the cells narrow and displace the hydraulic fluid via the pressure channel (P) into the system.
Pressure control
The stator ring (5) is held in the eccentric initial position by the spring (6). The maximum operating pressure required in the system is set at the set screw (7) using the spring (6).
The pressure building up by the load resistance acts at the pressure side on the inner sliding surface of the stator ring (5), against the force of the spring (6).
If the pressure corresponding to the set spring force has been reached, the stator ring (5) is pushed out of its eccentricity in zero position direction. The flow settles at the set value which is just removed. If the peak pressure set at the spring (6) is reached, the pump controls the flow to almost zero. The operating pressure is maintained and only the leakage is replaced. In this way, the power loss and heating of the hydraulic fluid are kept to a minimum.

Thanks to their specific design, PV7-type vane pumps with adjustable displacement boast low flow pulsation and achieve very high repetition accuracies with low pressure peaks during the down control. The noise optimization achieved by adjusting the height adjustment screw provides for a low operating noise. Hydrodynamically lubricated plain bearings ensure a long life cycle.

Adjust useful volume of the tank to the operating conditions. The admissible fluid temperature must not be exceeded; use coolers, if necessary.
Lines and connections
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.Proposal for piping layout
Minimum dimensions [mm]
Lay the leakage line so that the pump cannot run empty! Leakage and return fluid must not be directly sucked in again under any circumstances!
Filter
Use a 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 data sheet 90220. 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 hydraulic fluid must be renewed at certain time intervals. In this connection, it is also necessary to clean the hydraulic fluid tank from residues.Drive
Electric motor + pump carrier + coupling + pump
No radial and axial forces on the pump drive shaft admissible! Motor and pump must be exactly aligned! Use a torsionally flexible coupling.
