A4VG56 Control Configurations
The A4VG56 Series 32 is available with several displacement control systems. The control designation forms an important part of the complete pump model and should be checked together with the Rexroth part number.
Electrical proportional control, commonly found in earlier and application-specific configurations.
Proportional electric control with different solenoid voltage configurations.
Automatic speed-related displacement control.
Hydraulic proportional control and related variants.
Hydraulic mechanical-servo control configurations.
Two-point electrical displacement control.
How to Identify an A4VG56 Hydraulic Pump
The A4VG56 designation identifies the nominal pump size, but the complete model code is required to determine the exact configuration. Control type, rotation, mounting arrangement, shaft configuration and other options can vary between pumps.
The Rexroth part number (PN) is another useful reference when identifying an A4VG56 replacement pump. Pumps with the same 56 cm³/rev displacement may have different model codes and part numbers.
If you need an A4VG56 replacement hydraulic pump, send us the complete model code, Rexroth PN or a clear photo of the pump nameplate. We can check the corresponding replacement configuration.
A4VG56 Hydraulic Pump Spare Parts
Replacement components are available for Rexroth A4VG56 hydraulic pumps, including individual components and complete rotary group assemblies.
A4VG56 Hydraulic Pump Applications
The A4VG56 is used in closed-loop hydrostatic transmission systems where variable displacement and bidirectional hydraulic flow are required.
Typical applications include construction machinery, agricultural equipment, mobile hydraulic systems, industrial machinery and hydrostatic drive applications.
