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
