Application Range of A7VO80 Hydraulic Pump

1.1 Construction Machinery

The A7VO80 is widely used in construction equipment because of its excellent power density, high pressure capability, and precise flow control.

Typical applications include:

  • Excavators
  • Mini and medium-sized excavators
  • Wheel loaders
  • Hydraulic cranes
  • Concrete pumps
  • Road rollers
  • Drilling machines
  • Piling machines
  • Underground construction equipment

In construction machinery, the A7VO80 supplies hydraulic power for:

  • Boom, arm, and bucket cylinders
  • Hydraulic swing systems
  • Travel drives
  • Hydraulic attachments
  • Auxiliary hydraulic circuits

The variable displacement function allows the pump to adjust hydraulic flow according to actual load requirements. This reduces unnecessary power consumption and improves fuel efficiency, especially in machines operating with frequent load changes.


2. Mining Equipment Applications

Mining equipment requires hydraulic components capable of operating under high pressure, heavy vibration, and continuous working conditions.

The A7VO80 is suitable for:

  • Mining loaders
  • Underground mining vehicles
  • Rock drilling machines
  • Crushing equipment
  • Material transportation machines
  • Mining maintenance equipment

Advantages in mining applications:

  • High pressure operation up to 350 bar
  • Strong resistance against shock loads
  • High mechanical durability
  • Stable performance during continuous operation
  • Low maintenance requirements

The bent-axis piston design provides high torque capability and excellent resistance to mechanical stress, making it suitable for demanding mining environments.


3. Drilling Machinery Applications

The A7VO80 is commonly installed in drilling equipment requiring accurate hydraulic control and reliable power output.

Applications include:

  • Rotary drilling rigs
  • Geological exploration equipment
  • Anchor drilling machines
  • Water well drilling systems
  • Foundation drilling equipment

Main advantages:

  • Fast response to load variation
  • Smooth hydraulic output
  • High volumetric efficiency
  • Excellent pressure stability

The pump can maintain stable performance during drilling operations where hydraulic pressure changes rapidly.


4. Forestry Machinery Applications

Forestry machines require compact and durable hydraulic systems because of harsh working environments.

A7VO80 applications include:

  • Forestry harvesters
  • Log loaders
  • Wood processing machines
  • Tree cutting equipment

Hydraulic functions powered by the A7VO80 include:

  • Hydraulic arms
  • Grippers
  • Cutting heads
  • Rotation systems

Its high efficiency and compact design help improve machine productivity while reducing energy losses.


5. Agricultural Machinery Applications

The A7VO80 can also be applied in high-performance agricultural machines:

Examples:

  • Large tractors
  • Agricultural loaders
  • Specialized harvesting machines
  • Municipal maintenance vehicles

It provides hydraulic power for:

  • Hydraulic lifting systems
  • Implements
  • Steering systems
  • Auxiliary hydraulic functions
