<strong>Axial</strong> piston pump<br />
<strong>Series</strong> <strong>PV</strong><br />
Efficiency and case drain flows <strong>PV</strong>063, <strong>PV</strong>080, <strong>PV</strong>092<br />
The efficiency and power graphs are measured at an<br />
input speed of n = 1500 min-1 , a temperature of 50°C and<br />
a fluid viscosity of 30 mm2 /s.<br />
Case drain flow and compensator control flow leave via<br />
the drain port of the pump. To the values shown are to be<br />
added 1 to 1.2 l/min , if at pilot operated compensators<br />
(codes FR*, FF*, FT*, horse power compensator and p-<br />
Q-control) the control flow of the pressure pilot valve also<br />
goes through the pump.<br />
Please note: The values shown below are only valid for<br />
static operation. Under dynamic conditions and at rapid<br />
compensation of the pump the volume displaced by the<br />
servo piston also leaves the case drain port. This dynamic<br />
control flow can reach up to 80 l/min! Therefore the<br />
case drain line is to lead to the reservoir at full size and<br />
without restrictions as short and direct as possible.<br />
