Lukas P 650 Series - Manual (Page 15)

15
LUKAS hydraulic units are equipped with a double-
À ow or four-À ow pump depending on the
type. The pumps are permanently connected to the connecting block.
Double-
À ow pump for operation with SIMO valve
Four-
À ow pump for operation with 4POWER valve
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 (LP) = up to 14 MPa*
High-pressure level (HP) = up to 70 MPa*
The changeover from low pressure to high pressure is carried out automatically in the pump.
The maximum pressure is limited by a pressure limiting valve.
5.5 Pumps
*) 1 MPa = 10 bar
5.6 Frame with side parts
A surrounding frame is
¿ tted to all the hydraulic units described here, without exception.
The frame and the side parts are designed to protect the unit from external in
À uences (e.g.
dirt, damage, etc.), to attach accessories (e.g. Toolholders) and as a means of transporting
the unit by the frame itself or the optional carrying handles.
The starter equipment and accelerator cable regulator on units with a combustion engine are
mounted on the frame or side parts.
5.7 Connection to the rescue equipment
Connection with the rescue equipment is via extension hose pairs or hose reels. These are
available in various lengths and coloured bend protections.
Different colours distinguish the individual hose lines in a hose pair.
(For specifi c details, please consult the LUKAS range of accessories or contact your
LUKAS dealer).
WARNING / CAUTION / ATTENTION!
For reasons of safety, the pressure set on this valve must not be adjusted
(without direct authorisation from LUKAS)!
