Determining the operating characteristics
| Flow | qv=(Vg×n×ηv)/1000 | [l/min] |
| Torque | T=(Vg×Δp)/(20×π×ηhm) | [Nm] |
| Power | P=(2π×T×n)/60000=(qv×Δp)/(600×ηt) | [kW] |
Key
Vg=Displacement per revolution [cm3]
Δp=Differential pressure [bar]
n=Speed [rpm]
ηv=Volumetric efficiency
ηhm=Hydraulic-mechanical efficiency
ηt=Total efficiency ( ηt=ηv × ηhm)
Note
▶Theoretical values, without efficiency and tolerances;values rounded.
▶Operation above the maximum values or below the minimum values may result in a loss of function,a reduced service life or in the destruction of the axial piston unit. Other permissible limit values, such as speed variation, reduced angular acceleration as a function of the frequency and the permissible angular acceleration at start (lower than the maximum angular acceleration) can be found in data sheet 90261.
1) The values are applicable:
- for the optimum viscosity range from νopt = 36 bis 16 mm2/s
- for hydraulic fluids based on mineral oils.
2) The values apply at absolute pabs =1 bar at suction port S
3) Maximum speed (speed limit) with increased inlet pressure pabs at suction port S (see diagram).

Note
▶The values given are maximum values and do not apply
to continuous operation.
▶The permissible axial force in direction -Fax is to be avoided as the lifetime of the bearing is reduced.
▶Radial forces are not permissible.
