1 The values apply at absolute pressure(pabs)15 psi(1 bar)at the suction port S and mineral hydraulic fluid.
2)The values apply at Vg≤Vg ma or in case of an increase in the inlet pressure pabs at the suction portS(see diagram page 6) 3)The area of validity is situated between O and the maximum permissible speed.
t applies for external stimuli(e.g.engine 2 to 8 times rotary frequency,cardan shaft twice the rotary frequency). The limit value applies for a single pump only.
The loading on the connection parts has to be considered. Caution
Exceeding the permissible limit values could cause a loss of function,reduced service life or the destruction of the axial piston unit.The permissible values can be determined by calculation.
