Product Description
Rexroth A4VG40 Series (Series 32) Closed Circuit Variable Piston Pump
Product Overview: The Rexroth A4VG40 is a high-performance variable displacement pump engineered specifically for Closed Circuit hydrostatic transmissions within the renowned Series 32 family. Featuring a 40cc displacement and a rated operating pressure of 400 Bar, the A4VG40 serves as the heart of mobile machinery drive trains. It integrates a charge pump, high-pressure relief valves, and sophisticated control options such as EP (Electric Proportional) and DA (Speed-related). Its superior power density and compact footprint deliver precise stepless speed regulation and powerful traction for medium and small-sized mobile equipment.
Key Technical Advantages:
Efficient Closed-Loop Architecture: Optimized for travel drives. Direct fluid circulation between the pump and motor ensures rapid response and high energy efficiency, providing excellent braking capabilities.
Versatile Precision Controls:
EP4 Electric Proportional Control (A4VG40EP4): Precise displacement modulation via proportional solenoids, supporting digital control for smooth and repeatable driving characteristics.
DA Speed-Related Control (A4VG40DA1): Displacement automatically adjusts relative to drive speed, providing an intuitive “driving feel” ideal for forklifts and telehandlers.
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 continuous load.
Highly Integrated Design: Internal integration of the charge pressure valves and high-pressure relief valves streamlines external plumbing and minimizes potential leakage points.
Through-Drive Performance (F02/F09): Supports tandem mounting of secondary pumps (piston or gear) to power multiple machine functions, such as steering or auxiliary hydraulics, from a single drive shaft.
