In the S6CV pump it is possible to provide a filter in the suction line but we recommend to use the optional pressure filter on the out-let line of the charge pump. The filter on the charge pump out-let line is supplied by Dana while if the filter assembled in the suction line is used the following recommendation applies:
Install the filter on the suction line of the auxiliary pump. We recommend to use filters with clogging indicator, no by-pass or with by-pass plugged and filter elementrating of 10 μm absolute. The maximum pressure drop on the filtration element must not exceed 0.2 bar [3 psi]. A correct filtration helps to extend the service life of axial piston units.In order to ensure a correct functioning of the unit, the max. permissible contamination class is 20/18/15 according to ISO 4406:1999.
Suction pressure:
The minimum absolute pressure on the auxiliary pump suction must be of 0.8 bar [11.6 absolute psi]. On cold starting and for short- periods an absolute pressure of 0.5 bar [7.25 psi] is allowed. In no case inlet pressure can be lower.
Operating pressure:
Main pump: The maximum permissible continuous pressure on pressure ports is over 400 bar [5800 psi]. Peak pressure is 450 bar [6525 psi]. Charge pump: The nominal pressure is 22 bar [319 psi]. Maximum admissible pressure is 40 bar [580 psi].
Case drain pressure:
Maximum case drain pressure is 4 bar [58 psi]. On cold starting and for short-term a pressure of 6 bar [86 psi] is allowed. A higher pressure can damage the input shaft seal or reduce its life.
Seals:
Standard seals used on S6CV pumps are of FKM (Viton ®). In case of use special fluids, contact Dana.
Displacement limiting:
The pump is equiped with the externally adjustable mechanical displacement limiting device. Displacement limitation is obtained by means of two setting screws which limit the control piston stroke.
Input shaft Radial and Axial loads:
The input shaft can stand both radial and axial loads. The maximum permissible loads are in the following table.
