Spare parts ► A4VO series Bosch Rexroth Hydraulic parts

Main advantages of Bosch Rexroth A4VO series hydraulic pumps

• Adjustable displacement: Thanks to the possibility of infinitely variable displacement, A4VO pumps allow you to adjust the performance to the needs of the system.
• High working pressure: A4VO series pumps support working pressures up to 400 bar (peak up to 450 bar), which allows them to be used in highly loaded hydraulic systems.
• High performance: Optimized design ensures a stable supply of working fluid, minimizing energy loss and ensuring efficient operation even in difficult conditions.
• Compact and modular design: The compact dimensions allow the pump to be integrated into systems with limited space, and the modular design facilitates maintenance and component replacement.
• Modern management system: various types of management, including:
  • Hydraulic.
  • Electrohydraulic.
  • Proportional.
• Low noise: Improved design reduces vibration and noise levels, which contributes to more comfortable use, especially in mobile applications.
• Energy efficiency: Adjusting the fluid supply according to the load allows for reduced energy consumption and reduced operating costs.
• Reliability in severe conditions: A4VO series pumps are designed to operate in severe conditions, including high temperatures, contaminated working fluids and significant mechanical loads.
• Versatility of application: Pumps are widely used in open hydraulic systems in the following industries:
  • Construction equipment (excavators, cranes, road machines).
  • Agricultural machinery (tractors, combines, sprayers).
  • Industrial hydraulic systems.
• Ease of maintenance: Easy component replacement, standard components, and durable design reduce downtime and maintenance costs.
• Wide range of models: The A4VO series is available in different displacements, allowing you to choose the optimal pump for a specific system.
• Main Technical Specifications Bosch Rexroth A4VO:
  • Displacement: from 40 to 500 cm³ (depending on model).
  • Maximum pressure: 400 bar (working) and 450 bar (peak).
  • Control system: hydraulic or electro-hydraulic.
