Spare parts ► A4VG series Bosch Rexroth Hydraulic parts

Main advantages of Bosch Rexroth A4VG series hydraulic pumps

• Adjustable displacement: A4VG pumps have the ability to smoothly adjust the displacement (from 0 to maximum value), which allows you to adapt the performance to specific operating conditions.
• Increased working pressure: Maximum working pressure up to 450 bar (peak up to 500 bar), which ensures the ability to operate in highly loaded systems.
• High efficiency: Optimized design ensures low hydraulic losses and high energy transfer efficiency.
• Compact and lightweight: Thanks to their compact design, A4VG pumps are ideal for mobile applications where minimal dimensions and weight are important.
• Reliability in closed systems: Designed specifically to work in closed hydraulic circuits, ensuring stability and durability in operation.
• Control system: Pumps can be equipped with various control systems (hydraulic, electro-hydraulic, proportional, etc.), which allows them to be flexibly configured for various tasks.
• Built-in make-up pump: A built-in high-performance make-up pump ensures reliable fluid supply to the system, reducing the risk of cavitation.
• Versatility of application
  • Used in mobile technology, for example:
    • Excavators
    • Forklifts
    • Drilling rigs
    • Agricultural machinery
  • Suitable for industrial applications:
    • Hydraulic presses
    • Conveyor drives.
• Energy efficiency: Adjustable displacement reduces system energy consumption, which reduces operating costs.
• Noise reduction: The improved pump design helps reduce noise levels, which is important for the comfortable operation of mobile equipment.
• Easy maintenance: The modular design provides easy access to pump components, simplifying maintenance and repairs.
• Key features:
  • Displacement: from 40 to 250 cm³ (depending on model)
  • Maximum pressure: up to 450 bar
  • Temperature range: wide temperature limits allow the pump to be used in a variety of conditions
