Frequently Asked Questions (FAQ)
A1: These variable displacement axial piston pumps are specifically designed with a swash-plate rotary group for hydrostatic drives operating in open circuit systems.
A2: The flow rate is directly proportional to both the drive speed and the pump displacement. By adjusting the swash-plate angle, the displacement can be infinitely varied to match system demands.
A3: Series 52 is available in sizes (NG) 10, 28, 45, 60, and 85. Series 53 expands the range and offers sizes 18, 28, 45, 63, 72, 85, and 100.
A4: The series supports a variety of control options, including hydraulic pressure controllers (DR), flow controllers (DFR/DFR1/DRSC), pressure cut-offs (remotely operated or electric), differential pressure controls, and power controls with pressure cut-off.
A5: The pumps feature FKM (fluor-caoutchouc) seals as standard (marked as code V). Available drive shafts include standard splined shafts (ANSI B92.1a) for various torque specifications and parallel keyed shafts (DIN 6885).
A6: Yes, through-drive options are available depending on the working port configuration. Ports at the side (code 12) are designed for through-drive configurations, while code N00 indicates a unit without a through-drive.
