Product Description
Rexroth A4VTG90 Series Concrete Mixer Axial Piston Variable Pump
Product Overview: The Rexroth A4VTG series is a high-performance axial piston variable pump specifically engineered for Concrete Transit Mixer drum drives. Operating in a closed circuit, the A4VTG90 is the global industry standard, renowned for its compact swashplate design and ability to withstand the frequent start-stop and directional reversal cycles of construction machinery. Featuring integrated charge pumps and high-pressure relief valves, the series utilizes the proven HW Hydraulic Servo Control to ensure precise drum speed regulation and smooth directional switching during loading, transport, and discharge.
Key Technical Advantages:
Mixer-Specific HW Control: The A4VTG90HW model utilizes hydraulic servo manual control, allowing operators to precisely modulate drum speed and rotation (forward/reverse) via mechanical linkage, offering unmatched reliability and smoothness.
Integrated High-Pressure Closed Loop: Supports a rated operating pressure of 400 Bar (5800 PSI) with peak cycles up to 450 Bar. The integrated charge pump and valves simplify vehicle plumbing and enhance cooling efficiency.
Multi-Series Platform (Series 32 & 33):
Series 32 (A4VTG90HW/32L): The established industrial standard with high global spare part availability.
Series 33 (A4VTG090HW/33M): The latest revision offering optimized power density and extended bearing service life.
Superior Shock Resistance: Specifically optimized for the harsh environments of concrete mixers, the A4VTG features reinforced swashplate supports to maintain peak volumetric efficiency even under the high-pressure spikes caused by heavy concrete loads.
