Each power pack consists of an electric motor, a pump, a manifold and a tank. The aluminum
Die-cast Body forms the base of the power pack, on which all the main components, including the
hydraulic elements, are mounted. The function of the power packs is apparent from the respective
hydraulic circuit diagrams. The desired combination of particular components and hydraulic elements
can be defined by reference to the ordering code and the respective tables. The lay-out of additional
circuits is defined by an application number which determines the manufacturer.
The hydraulic circuits can be accomplished in sizes 03, 04 and 06. The size 03 is in a form of sectional
directional valves.
The mounting position of the power pack is either horizontal or vertical - see the Power Pack
Dimensions on pages 11 to 18. All ports have 9/16-18 UNF SAE J1926-1 internal threads.
With the standard model the connecting ports A, B of the components of the vertical stacking
assembly are oriented onto one side. Orientation of ports A, B each onto another side is to be agreed
with the manufacturer.
The basic combinations of electric motors and pumps, as well as their code designations, are shown
in tables 1, 2 and 3.
