Rexroth A7VO80 Pump | A7VO80LRH/61L | A7VO80EP | Axial Piston Variable Pump

Rexroth A7VO80 Series Axial Piston Variable Displacement Pumps

Product Overview: The Rexroth A7VO80 is a premier axial piston variable displacement pump designed for open-circuit hydraulic systems, featuring the classic Bent-Axis architecture. Renowned for its exceptional volumetric efficiency and self-priming capabilities, the A7VO80 is the standard choice for heavy-duty machinery. This featured selection includes core control configurations: from the electronically-controlled A7VO80EP, to the power-regulated A7VO80LRH/61L-PZB01, and the high-performance A7V080HD1/63L-NZB01. With its compact footprint and extreme reliability, this pump is widely utilized in crawler cranes, excavators, rotary drilling rigs, marine cranes, and large-scale industrial power units.

Key Technical Advantages:

• Superior Power-to-Weight Ratio: The bent-axis design allows for higher speeds and torque output while maintaining a compact profile, facilitating installation in congested engine compartments.

• Versatile Control Strategies:

  • EP (Electric Proportional Control): Enables precise, stepless flow regulation and seamless integration into electronic machine control systems.

  • LRH (Power Control): Automatically adjusts output flow to match load power, preventing engine stall and optimizing fuel efficiency.

  • HD (Hydraulic Direct Control): Provides rapid response times and stable hydraulic regulation performance.

• High-Pressure Resilience: Rated for continuous operation at 350 Bar (5000 PSI) with peak capabilities reaching 400 Bar (5800 PSI) for extreme duty cycles.

• Extended Service Life: Engineered with reinforced bearings and precision-matched piston assemblies to minimize internal friction and extend maintenance intervals.

• Target Applications: Heavy crane travel and hoist drives, concrete pump main drives, offshore winch systems, and industrial press power units.
