Model 1: A7VO80EP2/63R-VPB01

Product Overview

The A7VO80EP2/63R-VPB01 is a Bosch Rexroth A7VO Series 63 Series bent-axis axial piston variable displacement pump. The A7VO Series is Rexroth’s robust high-pressure pump line for open-circuit hydrostatic drive applications, featuring a bent-axis tapered piston design and covering sizes from 28 to 500. The A7VO80 delivers a maximum displacement of 80 cm³/rev.

This model features EP2 control—Electro-hydraulic proportional displacement control. EP2 control enables continuous, stepless displacement regulation via electric control current applied to the proportional solenoid. 63R denotes the Series 63 design platform with Right-hand rotation configuration. VPB01 is the shaft, mounting flange, and port configuration code.

As a direct OEM-equivalent replacement solution for the Bosch Rexroth A7VO Series, this product offers complete in-situ interchangeability, strictly adhering to Rexroth’s original design specifications and mounting interface standards. Every unit undergoes 100% simulated duty-cycle testing, ensuring that key performance metrics—including volumetric efficiency, pressure-flow characteristics, and case drain flow at rated pressure and full displacement—meet or exceed original factory specifications.

Key Technical Advantages

1. Bent-Axis Tapered Piston Design – Rugged and Durable
The A7VO Series features a bent-axis tapered piston design which, compared to swashplate designs, offers superior rigidity and optimized load distribution. The spherical contact surfaces between the tapered pistons and the drive flange better withstand radial loads and axial thrust, significantly extending pump service life—particularly suited for high-vibration, high-shock mobile equipment applications.

2. EP2 Electro-Hydraulic Proportional Control for Remote Precision Displacement Adjustment
EP2 control enables continuous stepless displacement regulation via electric control current applied to the proportional solenoid. Control current range is 200–600 mA with solenoid resistance of 22.7 Ω (at 20°C) . EP2 control is compatible with BODAS controllers and dedicated amplifiers, facilitating integration with vehicle electronic control systems (ECU, PLC). A pilot pressure of 40 bar is required to swivel the pump from Vg min to Vg max.

3. 350 bar Rated Pressure with 400 bar Peak Capacity
The A7VO80 delivers a rated working pressure of 350 bar (35 MPa) with peak pressures up to 400 bar (40 MPa) . At 80 cm³/rev displacement with 2240 rpm maximum speed, it outputs substantial hydraulic power.

4. Open-Circuit Dedicated Design for Flexible Application
The A7VO Series is specifically designed for open-circuit hydrostatic drives. Output flow is proportional to drive speed and displacement. By adjusting the bent-axis angle, flow is infinitely variable between maximum displacement and zero displacement. This design enables flexible adaptation to applications ranging from industrial machinery to mobile equipment.

5. Compact Design with Long Service Life
The A7VO Series features a short construction (Kurzbauende) with minimal axial length, making it particularly suitable for mobile equipment with constrained installation space. Combined with optimized bearings and high-precision friction pairs, the A7VO Series is renowned for its long service life (hohe Lebensdauer) .

Application Areas

• Concrete Mixer Trucks: Hydrostatic drive for mixer drum rotation

• Construction Equipment: Road rollers, pavers, skid steer loaders

• Agricultural Machinery: Combine harvesters, self-propelled sprayers

• Industrial Equipment: Injection molding machines, presses, and other open-circuit hydraulic systems

• Material Handling Equipment: Forklifts, stackers

Expert Maintenance Tips

1. Model Confirmation & Pre-Installation Inspection: Prior to installation, confirm the complete model code as A7VO80EP2/63R-VPB01. This is a Series 63 right-hand rotation configuration. Verify that the mounting flange specification and drive shaft type match the host machine PTO interface. Manually rotate the shaft before installation to confirm smooth, obstruction-free rotation.

2. Fluid Cleanliness Control: The A7VO Series recommends using high-quality mineral hydraulic fluid meeting Rexroth specifications. A minimum filtration rating of ISO 18/15 is recommended. Complete system flushing is mandatory before initial start-up.

3. EP2 Electro-Hydraulic Proportional Controller Tuning: EP2 control regulates displacement via electric control current. Control current range is 200–600 mA. Commissioning requires coordination with a proportional amplifier or BODAS controller for parameter setting. Ensure pilot pressure is not低于 40 bar—otherwise full displacement regulation cannot be achieved. Perform initial settings under no-load conditions, then gradually increase load to target operating conditions with fine adjustments.

4. Initial Start-Up & Priming: Before first start-up, pre-lubricate the pump by filling the housing with clean hydraulic fluid through the case drain port. Perform a brief jog start (5–10 seconds) to confirm correct rotation direction (right-hand), and check for abnormal noise or leakage. Then正式 start the pump and run at low load for several minutes to purge air from the pump and system lines.

5. Case Drain Port Positioning & Pressure Monitoring: During installation, ensure the drain port is positioned higher than the pump body to prevent oil starvation in the pump chamber after shutdown. Case pressure must not exceed 2 bar (absolute) . Install a pressure gauge on the case drain line for real-time monitoring.
