General: The axial piston unit must be filled with hydraulic fluid and air bled during commissioning and operation. This must also be considered with a long-term standstill.
Particularly with the “drive shaft up/down” installation position, filling and air bleeding must be carried out completely as there is, for example, a danger of dry running. The case drain fluid in the pump housing must be discharged to the reservoir via the highest available drain port (L, L₁). For combinations of multiple units, the case drain fluid must be drained off at each pump. We recommend laying separate drain lines. If this is not possible, a shared drain line may need to be laid. If a shared drain line is used for this purpose, make sure that the case pressure in each pump is not exceeded. In the event of pressure differences at the drain ports of the units, the shared drain line must be changed so that the minimum permissible case pressure of all connected units is not exceeded in any situation. If this is not possible, separate drain lines must be laid if necessary.
To achieve favorable noise values, decouple all connecting lines using elastic elements and avoid above-reservoir installation.
In all operating conditions, the suction line and drain line must flow into the reservoir below the minimum fluid level. The permissible suction height hs results from the overall loss of pressure. However, it must not be higher than hs max=31.50 in (800 mm). The minimum suction pressure at port S (see the technical data on page 64) must not be fallen short of during operation and at cold starting either. When designing the reservoir, ensure that there is sufficient distance between the suction line and the drain line. This prevents the heated, return flow from being drawn directly back into the suction line.
Installation position
See the following examples 1 to 9. Further installation positions are available upon request. Recommended installation position: 1 and 3
Below-reservoir installation (standard)
Below-reservoir installation is when the axial piston unit is installed outside of the reservoir below the minimum fluid level.
Note: Port F is part of the external piping and must be provided by the customer to make filling and air bleeding easier.
Above-reservoir installation
Above-reservoir installation means the axial piston unit is installed above the minimum fluid level of the reservoir. To prevent the axial piston unit from draining in position 5, the height difference hES min must be at least 0.98 in (25 mm). Observe the maximum permissible suction height hs max=31.50 in (800 mm).
A check valve in the case drain line is only permissible in individual cases. Consult us for approval.
1) Because complete air bleeding and filling are not possible in this position, the pump should be air bled and filled in a horizontal position before installation.
Inside-reservoir installation
Reservoir installation is when the axial piston unit is installed in the reservoir below the minimum fluid level. The axial piston unit is completely below the hydraulic fluid.
If the minimum fluid level is equal to or below the upper edge of the pump, see chapter “Above-reservoir installation”.
Axial piston units with electrical components (e.g., electric control, sensors) may not be installed in a reservoir below the fluid level.
Assembly note: Due to the compact design of the casing, socket-head screws with a hexagon socket must be used to attach the axial piston pump. Please observe the maximum permissible surface pressure according to VDI2230. Apart from this, you should take into account the information regarding tightening torques in the operating instruction.
