Product Description

Rexroth A4VG Series High-Pressure Closed Circuit Variable Pumps

Product Overview: The Rexroth A4VG series is the premier global benchmark in hydrostatic transmission (HST) technology. Engineered specifically for high-pressure closed-circuit systems, this series spans a full displacement spectrum from 28cc to 250cc, with featured models such as the A4VG140EP4DT1/32L-NSF02N001EH-S. Known for its exceptional power density and extreme reliability, the A4VG is the heart of travel drives for crawler excavators, rotary drilling rigs, and heavy-duty rollers. It provides precise flow modulation and smooth direction reversal at continuous operating pressures up to 400 Bar.

Key Technical Advantages:

  • Precision Electric Control (EP4): Features advanced electro-proportional displacement control (EP), ensuring delicate handling and perfect synchronicity for excavators on complex terrains.

  • Heavy-Duty High-Pressure Ratings: Rated for continuous operation at 400 Bar (5800 PSI), with peak capabilities up to 450 Bar. Reinforced rotating groups handle 24/7 high-intensity construction duty cycles.

  • Fully Integrated Closed-Loop Solution: Highly integrated design includes built-in charge pumps, high-pressure relief valves, and charge relief valves, simplifying the hydraulic system layout.

  • Extended Service Life: Equipped with oversized pre-loaded bearings to ensure robust performance even under harsh conditions involving contaminated oil or high operational temperatures.

  • 100% OEM Excavator Standard: Adheres strictly to Rexroth Series 32 design specifications, ensuring splined shafts and flanges align perfectly for a seamless “drop-in” replacement for brands like Caterpillar, Komatsu, Sany, and more.

Detailed Models & Parameters:

  • Core Series: Rexroth A4VG Series 32 & 40.

  • Full Displacement Range: 28, 40, 56, 71, 90, 125, 140, 180, 250 cm³/rev.

  • Model Keywords: A4VG140EP4DT1, A4VG140, A4VG250, A4VG125.

  • Pressure Ratings: Rated at 400 Bar (5800 PSI); Peak capability up to 450 Bar.

  • Control Types: EP (Electric Proportional), HD (Hydraulic Pilot), HW (Manual).

  • Target Applications: Excavator travel pumps, rotary rig power heads, concrete mixer drives, and heavy bulldozers.
