Product Description:
Variable displacement pump, axial piston pump, bent axis design for hydrostatic transmission in open circuites.
The flow is proportional to the drive speed and the displacement and is steplessly variable at constant drive speed.
Comprehensive programme of control devices for every control and regulation function.
Operation of both mincral, and fire-resistant fluids.
Product Features:
--  High performance rotary group with well-proven spherical control area offering the following advantages, self-centering.
--  Low periph-eral speed               
--  High efficient.
--  Long service life robust rolling bearing.        
--  Drive shaft will support radial loads.
--  Low noise level.
--  High duty roller bearing for intermettent high pressure operation.
--  For continuous duty hydrostatic are availabe.
--   Excellent  starting characteristics.
--  High power density
--  Optional mounting position

The above data would be right when there is 0.1 MPa absolute pressure in the oil suction port S.
Pressure Range:
Port S(inlet) absolute pressure: Ps min=0.8bar Ps max=3MPa
Port B(outlet) pressure:rated pressure P=35 MPa Peak Press.=40MPa
a: the pump housing must be filled with fluid both when commissioning and in operation.
b: in order to achieve low noise levels, all connecting lines are to be isolated from the tank by flexiable members.
c: a non-return line in the drain lines should be avoided , drain oil pressure is 0.2 MPa(absolute pressure)
d: with vertical mounting , in order to ensure lubrication of front bearing and shaft seal, we recommand bearing flushing .
    The bearing flushing port U is located in the mounting flange area of the pump.
    The flushing oil flows through the pump's front bearing and leaves via the case drain.
    There will be a pressure difference of 0.2 MPa between port U and the pump drain port T.
