A Detailed Description On The A4VG Series:
Being flexible and adaptable has made the Rexroth A4VG series popular among many industries as they offer different types of models depending on one’s needs. Here are some key details:
Displacement Ranges
Variety is the spice of life, so too with hydraulic power units; this means there must be multiple displacement volumes available in hydraulic systems like the one mentioned above. Different hydraulic power requirements call for different sizes of pumps which are all under one brand name A4VG by Rexroth.
- 40 cm³/rev
- 56 cm³/rev
- 71 cm³/rev
- 90 cm³/rev
- 125 cm³/rev

- 250 cm³/rev
Flow rate needed varies from one application to another, hence they are designed such that flow rates can be adjusted according to the pressure rating it should offer without affecting other parts’ performance, thus making their usability quite wide.
Pressure Ratings
Rexroth A4VG pumps can operate under high-stress conditions while still delivering peak performance levels required continuously over time without failing once subjected to severe working environments. Continuous pressures up to 350 bar or higher than 400 bar peak values.
Temperature Ranges
Hydraulic systems work best within specific temperature margins, which if exceeded may result in inefficient operation or even total failure due to wear and tear caused by extreme heat or coldness. The A4VG pumps are designed to operate efficiently within a range of -25°C to +90°C, allowing usage within wider climatic zones.
Other Features
- Efficiency: The internal design has been optimized for high volume as well as mechanical efficiency, making it work better than any other model within its range.
- Noise Levels: Low noise emissions allow this machine to operate in areas where there are strict regulations regarding sound pollution, making it suitable for use in quiet environments like hospitals and schools.
- Weight: Depending on the size chosen, weight may vary from 25 kg minimum to 75 kg maximum specification limit.
- Mounting Configuration: Various mounting options are available for selection according to different machine designs, ensuring compatibility regardless of variations found between two machines working side by side within the same area code.
- Fluid Compatibility: It works well with most hydraulic fluids commonly used such as mineral oil-based products, fire-resistant types, synthetic esters, among others.

Working Philosophies
The A4VG Axial Piston Variable Pump by Rexroth is based on advanced hydraulic principles that ensure accurate and effective delivery of hydraulic power. It is therefore vital to have a good understanding of these working philosophies so as to maximize its use in different industries.
How the Pump Operates
In the design of Rexroth’s A4VG pump, an angle set for a swash plate determines how much the pump will displace. The cylinder block has pistons arranged in axial configuration where each stroke changes with respect to varying swashplate angles, thereby altering the volume per cycle displaced by fluid.
Piston Movement: These pistons are driven back and forth inside a cylinder block by rotating swash plate. This can be adjusted because it varies the length of strokes.
Intake and Output of Fluids: When retracting, they create space within themselves which draws oil into them under pressure; conversely, when extended they push out oil at high pressure creating required power for any given operation in hydraulics.
Swash Plate Adjustment: The control system may either adjust automatically or manually depending on whether there is need for self-regulation or not (external regulation). It controls this variable through changing flow rate from one side to another while holding constant output pressure levels thus giving fine-tuning capability over delivered hydraulic energy.
Variable Displacement Mechanism
One feature that makes Rexroth A4VG pump exceptional is its ability to change according to different demands put forward by various hydraulic systems; achieved through displacement variation mechanism governed by control units like electronic controllers among others which alter angles of inclination known as swash plates thus determining pumps displacements.
Load Sensing: There exists provision where load sense could be added onto such type pumps making them adjust their displacement through altering swivel angle magnitude basing on what loads require so that unnecessary power is not produced thereby saving energy also improving efficiency.
Pressure Compensation: In applications where constant pressure is needed, this can be achieved by adjusting pump’s displacement until output matches system requirements keeping it steady all along.
Electronic Control: Some advanced versions of A4VG pumps have electronic controls that allow more accurate setting modifications to improve reliability and overall performance.
Efficiency and Performance Advantages
The operating principles of the Rexroth A4VG pump bring about various efficiency and performance benefits:
Energy Saving: By changing how much oil gets pumped out depending on work done or load capacity, wastage will be minimized thus making systems operate at higher efficiencies generally saving power consumption levels also.
Accurate Control: It ensures accuracy in controlling machines or processes which can lead into increased productivity due to faster cycle times resulting from better response rates as well safety enhancements through finer adjustments being made available on demand basis.
Reduced Tear And Wear: Because pumps have adjustable output volumes, unnecessary wear tear situations are eliminated thereby extending their lifespan besides reducing maintenance costs.
