Rexroth A4VG Closed-loop piston pump for Metso Minerals equipment MM0302673 MM0520475 9651097200 9650944000 925710 N05550252

The Rexroth A4VG series closed-loop piston pump is engineered specifically for high-performance applications in Metso Minerals equipment, such as mobile crushers, screens, and grinding mills. It serves as the core component in hydrostatic drives, delivering precise speed and torque control for demanding material processing operations.

This axial piston, variable displacement pump operates in a closed-circuit configuration, meaning it directly recirculates hydraulic fluid to the associated motor, enhancing efficiency and thermal management. Its key advantages for mining and aggregate machinery are:

• High Power Density & Pressure Capability: With continuous operating pressures up to 400-450 bar, it delivers substantial power from a compact footprint, crucial for space-constrained mobile equipment.

• Precision Control: Integrated electro-hydraulic control (e.g., HD type) allows for precise, proportional regulation of displacement via an electrical input signal. This enables seamless control of travel and process speeds from Metso’s automation system.

• Rugged Durability: Designed to withstand the extreme conditions of mineral processing, including high shock loads, vibration, and particulate contamination. Its robust construction ensures reliability and long service life.

• High System Efficiency: The closed-loop design minimizes losses, and features like the auxiliary pump for supercharging optimize efficiency, reducing overall energy consumption.

• Integrated Functionality: The pump often incorporates essential valves (e.g., high-pressure relief, cross-port relief) and an auxiliary gear pump for charge pressure and servo control within a single unit, simplifying system design.

In Metso’s machinery, the A4VG pump enables smooth starting, accurate travel maneuvers, and efficient power management, directly contributing to high machine availability, productivity, and lower total cost of ownership. Its reliability under extreme loads makes it a critical component for ensuring uninterrupted operation in harsh mining and quarrying environments.
