– The limitingvalue is only valid for a single pump. | |||||||||||||||
– The loading capacity of the connecting parts must be considered. | |||||||||||||||
Notes | |||||||||||||||
Exceeding the maximum or falling below the minimum permissible values can lead to a loss of function, a reduction in operational service life or total destruction of the axial piston unit. | |||||||||||||||
The permissible values can be determined through calculation. |
