Rexroth A8VO FAQ

The A8VO pump is recommended to use hydraulic fluids as detailed in the data sheets RE 90220 for mineral fluids, RE 90221 for environmentally acceptable pressure fluids, and RE 90223 for HF pressure fluids. It is crucial to select the hydraulic fluid so that the operating viscosity lies within the optimum range of 16 to 36 mm²/s for optimum efficiency and service life.

The A8VO pump operates with a nominal pressure of 350 bar and a peak pressure of 400 bar. It is essential to maintain these pressures to avoid damage and ensure optimal performance.

The maximum permissible hydraulic fluid temperature for the A8VO pump is 115°C. Exceeding this temperature may lead to damage, particularly in the bearing area where the temperature can be up to 12 K higher than the average case drain temperature.

The viscosity of the hydraulic fluid should be maintained within the limits of 5 mm²/s to 1600 mm²/s. Short-term operation is permissible at these extreme viscosities, provided that certain conditions such as temperature and pressure are controlled.

Yes, the A8VO pump can be used with environmentally acceptable hydraulic fluids as specified in data sheet RE 90221. However, users must adhere to the limitations regarding technical data and seals as detailed in the manual.

For most sizes, the A8VO pump does not require an external drain line as the drain fluid chamber is internally connected to the suction chamber. However, the size 200 pump requires an external flushing fluid connection for cooling and lubrication of the bearing sets.

The tightening torques specified in the data sheet should not exceed the maximum values provided for the screw threads. It is advisable to check the tightening torque individually according to VDI 2230 standards, especially for DIN 13 fastening screws.
