Descrição detalhada
This is an axial piston variable pump with a swashplate design, specifically engineered for hydrostatic drive systems in open circuits, making it suitable for a wide range of industrial and mobile hydraulic applications. The pump’s output flow is directly proportional to its drive speed and displacement; by adjusting the swashplate angle precisely, the flow can be infinitely and steplessly varied, allowing flexible adaptation to the changing flow requirements of the hydraulic system during operation. It features a high power-to-weight ratio paired with small dimensions, which effectively saves installation space, reduces the overall weight of the supporting equipment, and simplifies layout in compact installation environments. Additionally, the pump operates at a low noise level, ensuring quiet and stable performance, which is ideal for noise-sensitive working sites. Its permissible continuous pressure is 210 bar, enabling reliable long-term operation under rated pressure conditions. The drive shaft supports both axial and radial loading, enhancing its adaptability to different installation configurations, and it is equipped with integrated pressure and flow control functions to achieve accurate regulation of the hydraulic system.

1)self priming with absolute pressure of 15 psi (1 bar) at inlet port S
2) -These values are valid for conditions between the min. required and the max. permissible drive speeds.
For external sources of excitation (eg. diesel engine 2-8 fold rotary frequency, cardan shaft 2-fold rotary frequency).
-The limit is valid for a single pump.
-The load carrying capacity of the connecting parts must be taken into consideration.
Caution:Exceeding these limits can lead to a loss of operability, reduction of service life or complete destruction of the axial piston unit.
