Vickers PVH131 Pump | PVH131R13AF30B, PVH131R13AF30A | Variable Piston Pump

Vickers PVH131 Series Heavy-Duty Axial Piston Variable Pump

Product Overview: The Eaton Vickers PVH131 series is a high-efficiency axial piston variable displacement pump designed to meet the rigorous demands of global mobile machinery and heavy industrial systems. As one of the largest displacement models in the PVH lineup, the PVH131 is renowned for its exceptional power density and superior shock resistance. Flagship models like the PVH131R13AF30B252000002001AB010A (Load Sensing) and PVH131R13AF30A2500000001AC1AA010A (Pressure Compensated) deliver continuous output at pressures up to 250 Bar. Its robust internal architecture and optimized swashplate design ensure remarkably low noise levels and extended service cycles even under the harshest operational conditions.

Key Technical Advantages:

• Superior Power Density: Delivers a massive 131cc displacement within a compact installation envelope, making it the preferred “power heart” for heavy construction equipment.

• Versatile Precision Control Mechanisms:

  • Pressure Compensator (C/CM): Automatically maintains preset system pressure, de-stroking the pump to standby upon reaching the setpoint to minimize energy loss.

  • Load Sensing (CV): Modulates flow in real-time to match load demand, reducing system heat and significantly improving overall fuel efficiency.

• High-Response & Fatigue Resistance: Reinforced for continuous high-pressure duty and frequent load fluctuations, with a rapid swashplate response for agile machine movements.

• Quiet-Tech Operation: Utilizes patented valve plate damping technology to effectively suppress fluid pressure pulsations, drastically improving the operator’s environment.

• 100% OEM Standard Compatibility: Manufactured to strict Vickers factory specifications (e.g., AF30 series), ensuring splined shafts, mounting flanges, and porting align perfectly for a seamless “drop-in” replacement.
