Rexroth A10VG Series Pump | A10VG45, A10VG63 | 300 Bar Closed Circuit Piston Pump

Rexroth A10VG Series (Series 10) Closed Circuit Variable Piston Pump

Product Overview: The Rexroth A10VG series is a high-performance swashplate-designed variable displacement pump engineered specifically for Closed Circuit hydrostatic transmissions. Covering essential displacements including 45cc (A10VG45) and 63cc (A10VG63), the A10VG serves as the heart of mobile machinery drive trains. Featuring an integrated charge pump and high-performance relief valves, it delivers a rated operating pressure of 300 Bar. With versatile control options such as EZ electric proportional control and HW hydraulic manual control, it provides precise stepless speed regulation and reliable traction for specialized vehicles.

Key Technical Advantages:

• Efficient Closed Circuit Architecture: Optimized for travel drives in mobile machinery. The closed-loop fluid circulation ensures rapid response, low system heat generation, and maximum energy efficiency.

• Versatile Precision Controls:

  • EZ2 Electric Proportional Control (A10VG45EZ2): High-precision displacement modulation via solenoid valves, offering excellent linearity for seamless integration with modern electronic drive systems.

  • HWD1 Hydraulic Manual Control (A10VG63HWD1): Hydraulic servo-assisted manual control requiring minimal operational force, providing tactile feedback ideal for harsh outdoor environments.

• Heavy-Duty Reliability: Rated for an operating pressure of 300 Bar (30 MPa) with peak capabilities reaching 350 Bar. Reinforced swashplates and bearing designs ensure an extended service life under extreme loads.

• Highly Integrated Design: Internal integration of charge relief and high-pressure relief valves simplifies external plumbing layouts and minimizes potential leakage points.

• Through-Drive Performance: Supports tandem mounting of secondary pumps (piston or gear) to power multiple machine functions from a single drive shaft.
