5.2 Motor variants
WARNING / DANGER / CAUTION!
For all motor variants, also comply with the separate operating instructions of
each motor manufacturer.
5.2.1 Electrical
These hydraulic units are equipped with an electric motor. The electric motor is driven by
electricity from the mains supply or by electricity produced by generators. In the case of
operation with generators, make sure that voltage fluctuations do not occur, as these have a
direct influence on the pumping capacity and stability of the hydraulic unit.
For the supported operating voltage and current frequency, please refer to the “Technical
data” chapter in the instruction manual for your unit.
5.2.2 Gasoline / petrol
These hydraulic units are equipped with a combustion engine driven by the fuel "gasoline /
petrol".
(For specific details, please consult the separate operating instructions of the engine
manufacturer.)
5.2.3 Diesel
These hydraulic units are equipped with a combustion engine driven by the fuel "diesel".
(For specific details, please consult the separate operating instructions of the engine
manufacturer.)
5.3 Pumps
Depending on the model, LUKAS hydraulic units contain a single-flow or multi-flow pump.
Single-flow pump
1 pump capacity
Double-flow pump
2 pump capacities
Triple-flow pump
3 pump capacities
etc.
The pumps used are always equipped with two pressure levels for each pump capacity, one
low-pressure and one high-pressure level.
Low-pressure level (ND) = up to 16 MPa*
High-pressure level (HD) = up to max. 53 MPa*
The changeover from low pressure to high pressure is carried out automatically in the
pump.
The maximum operating pressure is limited by a pressure limiting valve.
For information on how to adjust this valve to work with your hydraulic unit model, please
refer to the “Technical data” chapter.
*( 1 MPa = 10 bar)
