Rexroth Axial Piston Variable Pump A4VSO Description

2024-11-21
Rexroth A4vso is a variable displacement pump with an axial piston swash plate structure produced by Rexroth Rexroth, Germany. This pump is designed for use in hydraulic transmission systems, with a flow rate proportional to the driving speed and a displacement that can be infinitely adjusted. The output flow rate increases as the inclination angle of the swash plate changes from zero to the maximum value. Changing the inclination angle of the swash plate across the centerline can smoothly change the flow direction of the flow rate. This pump has excellent suction characteristics, sensitive control response, and is specially designed with long-life, high-precision aviation grade full roller bearings. In addition, it also has low noise, long lifespan, excellent power and weight ratio, and the through shaft structure can be stacked into a combination pump.

Rexroth A4VSO Piston Pump Features
- Through drive for mounting of further pumps up to same nominal size
- Axial Piston Pump in swash plate design for hydrostatic drives in open circuit operation
- The fl ow is proportional to the input drive speed and displacement. By adjusting the swash plate angle it is possible to infinitely vary the output fl ow.
- Excellent suction characteristics
- Low noise level
- Robust pump with very long service life
- Modular design
- Short control response times
- Variable through drive options
- Visual swivel angle indicator
- Optional mounting position
- Operation on HF-fluids under reduced operational data possible
- Robust high pressure pump for industrial applications
- Size 40 … 1000, such as A4VSO 40/DR, A4VSO 71/DP, A4VSO 125/DFR, A4VSO 180/LR, A4VSO 250/MA, A4VSO 355/EM, A4VSO 500/HM, A4VSO 750/HS, A4VSO 1000/HD, A4VSLO 750/DR.

The performance characteristics of Rexroth A4VSO include: High pressure capacity - Rexroth A4VSO has a high pressure bearing capacity and is suitable for applications that require high pressure hydraulic systems; The flow rate is directly proportional to the driving speed and displacement - The flow rate of Rexroth A4VSO is directly proportional to the driving speed and displacement, so the output flow rate can be continuously adjusted by adjusting the driving speed and displacement; Reliable and Durable - Rexroth A4VSO adopts high-quality materials and manufacturing processes, which have excellent durability and reliability, and are easy to maintain; Multiple Variable Methods - Rexroth A4VSO piston pump has multiple variable methods that are easy to match with various control and regulation systems, thus meeting different application needs; Flow rate varies with the swash plate angle - the flow rate of Rexroth A4VSO can vary with the swash plate angle, increasing from zero to its maximum value. This feature enables the pump to adapt to different working requirements. And by swinging the swash plate over the center position, Rexroth A4VSO can smoothly change the direction of liquid flow and achieve forward and reverse rotation; Multiple protection functions - Rexroth A4VSO is equipped with two relief valves on the high-pressure oil side to protect the hydrostatic transmission (pump and motor) from overload. The high-pressure relief valve also has the function of a makeup valve. In addition, the pump is equipped with an auxiliary pump as a makeup pump and control pump, and is equipped with a built-in pressure cutoff valve. Rexroth A4VSO is equipped with an auxiliary pump, which serves as a makeup pump and control pump, providing additional hydraulic power and control functions. The A4VSO series is equipped with a built-in pressure cut-off valve, which can automatically cut off the pump output when the system pressure is too high, thereby protecting the system from damage; Modular design - Rexroth pump A4VSO adopts a modular design, making it easier to expand and combine the A4VSO pump with other hydraulic components to meet the needs of different application scenarios. At the same time, it also makes pump maintenance more convenient; High efficiency - Rexroth piston pump A4VSO adopts an advanced swash plate design, which enables the pump to have efficient performance. This design makes the flow rate of the pump proportional to the input transmission speed and displacement, reducing energy loss and improving pump efficiency; Easy to maintain - The modular design and visible swing angle indicator of Rexroth hydraulic pump A4VSO make maintenance more convenient. Users can intuitively understand the working status of the pump, making monitoring and maintenance more convenient.

Rexroth plunger pump A4VSO is widely used worldwide due to its high efficiency, reliability, and durability, as well as advantages such as modular design, short response time, and optional installation positions. It is mainly used in high-pressure, high flow, high-power systems, and fields where flow needs to be adjusted. It is widely used in high-pressure and heavy-duty metallurgical conditions. Its control performance lies in maintaining a constant system pressure, only outputting the flow required to drive the load, reducing system heat generation, increasing efficiency, and saving energy. Rexroth A4VSO is also widely used in various industrial fields, including but not limited to: gantry planers, pullers, hydraulic presses, engineering machinery, concrete pump trucks, excavators, road rollers, ceramic presses, forging machines, automotive production line stamping machines, steel mill hydraulic systems, hydraulic driven blast furnaces, continuous casting machines, rolling mills, chemical hydraulic equipment, ship driven servos, ship anchors, deck machinery, aluminum die-casting machinery, etc.
