China Rexroth A11V Hydraulic Pump for Concrete Pump Trucks, Find details about China Rexroth Pump, Hydraulic Pump from Rexroth A11V Hydraulic Pump for Concrete Pump Trucks
Series | A11VO Axial Variable Piston Pump |
Specification | A11VO40, A11VO60, A11VO75, A11VO95, A11VO130, A11VO145, A11VO190, A11VO260 (Series 1) |
Working pressure | Common pressure 400 bar (40 Mpa), peak pressure 450bar (45 Mpa) |
Control mode: LR power control DR Constant Voltage Control HD hydraulic control, related to pilot pressure EP proportional control | Characteristic: The swashplate axial piston variable pump is used for hydrostatic transmission in open loop hydraulic system. Mainly designed for the application of walking machinery. Under the condition of tank pressurization or using optional built-in injection pump (impeller), the pump operates under the condition of automatic starting oil injection. Provide various control options to meet various application requirements. The power control options are adjustable externally, even when the pump is running. The through-axle drive is suitable for adding gear pump and axial piston pump, that is 100% through-axle drive. The output flow is proportional to the driving speed and can vary steplessly between qV Max and qV min = 0. |
