Product Description
Rexroth A4VG56 Series (Series 32) Closed Circuit Variable Piston Pump
Product Overview: The Rexroth A4VG56 is a high-performance variable displacement pump engineered specifically for Closed Circuit hydrostatic transmissions within the renowned Series 32 family. Featuring a 56cc displacement and a rated operating pressure of 400 Bar, the A4VG56 serves as the heart of mobile machinery drive trains. It integrates a charge pump, high-pressure relief valves, and sophisticated control options such as DA (Speed-related) and EZ (Electric proportional). Its compact design and superior power density make it the premier choice for traction drives in construction machinery and large-scale industrial closed-loop systems.
Key Technical Advantages:
Efficient Closed-Loop Architecture: Optimized for travel drives. Direct fluid circulation between pump and motor ensures rapid response and minimal energy loss, supporting bi-directional rotation and stepless speed modulation.
Versatile Precision Controls:
DA Speed-Related Control (A4VG56DA1): Automatically adjusts displacement based on drive speed, providing an intuitive “driving feel” ideal for wheel loaders and forklifts.
EZ1 Electric Proportional Control (A4VG56EZ1): Facilitates high-precision digital modulation, allowing seamless integration with modern automated control and remote driving systems.
Heavy-Duty High-Pressure Reliability: Rated for an operating pressure of 400 Bar (40 MPa) with peak cycles reaching 450 Bar. Reinforced rotating groups and swashplate designs ensure an extended service life under extreme duty cycles.
Highly Integrated & Compact Design: Internal integration of the charge system and pressure cut-off valves streamlines external plumbing and minimizes potential leakage points.
Through-Drive Performance (F00/F01): Supports tandem mounting of secondary pumps (piston or gear) to power multiple machine functions from a single drive shaft, such as steering or work hydraulics.
Detailed Models & Parameters:
Core Series: Rexroth A4VG Series 32.
Representative Models: A4VG56DA1D8/32R-NZC02F005S, A4VG56EZ1DM1/32R-NSC02F015S.
Displacement: 56 cm³/rev.
Pressure Ratings: Rated at 400 Bar (40 MPa); Peak capabilities up to 450 Bar (6500 PSI).
Rotation: R (Clockwise / Right-hand rotation).
