Rexroth A10VG & A4VG Piston Pump | A10VG45, A4VG180 | Closed Circuit Hydraulic Pump

Rexroth A10VG & A4VG High-Pressure Closed Circuit Piston Pump

Product Overview: The Rexroth A10VG and A4VG series are the gold standard for closed-circuit hydrostatic transmissions worldwide. The A10VG45 is engineered for medium-to-high pressure mobile machinery, while the A4VG180 is built for heavy-duty, high-pressure applications. These series feature integrated charge pumps and system relief valves, delivering exceptional power density in a compact frame. Core models like the A10VG45EP4 offer superior electronic proportional control, ensuring smooth and precise maneuverability for construction and agricultural equipment.

Key Technical Advantages:

• Fully Integrated Closed-Loop Design: Includes an on-board charge pump, charge pressure relief, and high-pressure relief valves. This simplifies hydraulic plumbing, reduces leak points, and is ideal for space-constrained mobile applications.

• Advanced Electro-Proportional Control (EP): Featuring EP4 technology (e.g., A10VG45EP4DM1), providing precise, stepless modulation of flow and direction with rapid response times.

• High-Pressure Durability: The A4VG180 model supports a rated pressure of 400 Bar and peak pressures up to 450 Bar, specifically designed for the most grueling construction environments.

• Peak Volumetric Efficiency: Optimized rotating groups (e.g., NSC10 and NSD02 specs) maintain stable torque output even under high temperatures and fluctuating oil viscosities.
