Rexroth A10VSO vs A4VG: What's the Difference?

Quanzhou, Fujian Aug 14, 2026 (Issuewire.com) - When selecting an axial piston hydraulic pump, engineers and equipment manufacturers often compare the Rexroth A10VSO and Rexroth A4VG series.

Although both are variable displacement axial piston pumps with swashplate design, they are engineered for completely different hydraulic systems and applications.

What Is the Rexroth A10VSO?

Main Features

• Swashplate axial piston design
• Variable displacement control
• High volumetric efficiency
• Low operating noise
• Through-drive capability for tandem pumps
• Multiple control options, including pressure, load-sensing, and power control

Typical Applications

The A10VSO is commonly used in:

• Hydraulic power units (HPUs)
• Injection molding machines
• Presses
• Machine tools
• Cranes
• Excavator working hydraulics
• Agricultural equipment

What Is the Rexroth A4VG?

Main Features

• Closed circuit design
• Integrated charge pump
• Bidirectional flow
• High-pressure operation
• Fast dynamic response
• Excellent speed and torque control
• Multiple hydraulic and electronic control options

Typical Applications

The A4VG is widely used in:

• Excavator travel drives
• Wheel loaders
• Road rollers
• Asphalt pavers
• Forestry machinery
• Mining vehicles
• Mobile construction equipment
