Type: It is a variable displacement axial piston pump with a swashplate design, mainly used for hydrostatic drives in open circuits.
Performance Specifications
Displacement: The displacements available in the 31 series are 18, 28, 45, 71, 88, 100, and 140 1.
Flow Rate: The flow is proportional to the drive speed and the displacement, and can be continuously changed with closed-loop control. The maximum flow rate depends on the displacement and the rotational speed of the pump. For example, for the A10VSO 45, at 1800 rpm, the flow is 81 l/min.
Pressure Ratings: The nominal pressure is 280 bar, and the peak pressure can reach up to 350 bar.
Rotational Speed
It can operate at different rotational speeds. Generally, it has a wide range of applicable rotational speeds to meet the needs of various working conditions. For example, the A10VSO 45 can operate at 1800 rpm.
Fluid Compatibility
It is suitable for operation with mineral oil and HF hydraulic fluids.
Input Power and Efficiency
The input power requirements vary depending on the operating conditions such as pressure, flow rate, and rotational speed. The pump is designed to have a favorable power/weight ratio, providing efficient power transmission and conversion.
It has relatively high volumetric and overall efficiencies, ensuring good energy utilization and performance.
Mounting and Configuration
Mounting Style: It usually has a flange-mounted configuration, with different flange types and installation hole patterns available. It also conforms to ISO standard mounting flanges and supports SAE metric flange connections.
Shaft Configurations: There are different shaft end options, such as a straight shaft with a key according to DIN 6885 (P), a splined shaft according to SAE (S), etc.
Through Drive: The pump has a through drive function, allowing it to be combined with gear pumps or axial piston pumps of the same size, which expands its application range and enables the formation of multi-circuit hydraulic systems
