Bosch Rexroth Axial piston variable pump A10VG Series 10

Key Technical Features

1. Integrated Boost Pump System
   • Provides dual functionality for both boost and pilot oil supply in a single compact unit
   • Eliminates need for external auxiliary pumps through self-contained design
   • Ensures consistent lubrication pressure during start-up sequences
2. Bi-Directional Flow Capability
   • Seamless flow reversal achieved through precision swashplate neutral crossing
   • Maintains hydraulic continuity during direction transitions
   • Particularly effective for applications requiring frequent directional changes
3. Advanced Pressure Management System
   High-Pressure Relief Valves
   • Integrated boost compensation maintains optimal pressure differentials
   • Factory-calibrated burst protection up to 350 bar
   • Thermal compensation ensures stable performance across operating temperatures

Dedicated Boost-Pressure Relief Circuit

• Independent pressure regulation for auxiliary systems
• Prevents cavitation during high-demand cycles
• Field-adjustable settings (150-250 bar range)

1. Enhanced Control Options
   • Pressure Cut-Off (Optional)
     • Automatic system deactivation upon reaching preset thresholds
     • Energy-saving mode reduces wear during standby operations
   • Modular Control Interface
     • Compatible with electro-hydraulic, manual, and servo controls
     • DIN-standard mounting provisions for aftermarket controllers
2. Precision Swashplate Mechanism
   • Forged alloy construction with hardened wear surfaces
   • Zero-clearance pivot bearing design minimizes internal leakage
   • 0.1° angular resolution for fine flow regulation
   • Maintenance-free operation up to 10,000 service hours

Design Advantages

• Compact axial piston configuration saves 30% installation space vs comparable units
• Interchangeable cartridge valves simplify field servicing
• SAE J743 compliant mounting pattern for universal integration
• Optional corrosion-resistant coating for marine applications

Hydraulic fluids
The axial piston unit is designed for operation with HLP
mineral oil according to DIN 51524.
Application instructions and requirements for hydraulic
fluid selection, behavior during operation as well as
disposal and environmental protection should be taken
from the following data sheets before the start of project
planning:
▶▶ 90220: Hydraulic fluids based on mineral oils and
related hydrocarbons
▶▶ 90221: Environmentally acceptable hydraulic fluids
▶▶ 90222: Fire-resistant, water-free hydraulic fluids
(HFDR/HFDU)
▶▶ 90225:Limited technical data for operation with
waterfree and water-containing fire-resistant hydraulic
fluids (HFDR, HFDU, HFAE, HFAS, HFB, HFC)

Filtration of the hydraulic fluid

Finer filtration improves the cleanliness level of the
hydraulic fluid, which increases the service life of the axial
piston unit.
A cleanliness level of at least 20/18/15 is to be maintained
according to ISO 4406.
At a hydraulic fluid viscosity of less than 10 mm²/s
(e.g. due to high temperatures during short-term operation)
at the drain port, a cleanliness level of at least
19/17/14 according to ISO 4406 is required.
For example, the viscosity is 10 mm²/s at:
▶▶ HLP 32 a temperature of 73°C
▶▶ HLP 46 a temperature of 85°C
