The main components of the Rexroth A4VG series pump include the housing, drive shaft, swashplate assembly, cylinder block, pistons, and valve plate.
These parts work in tandem to deliver variable displacement and hydraulic power. When selecting OEM or aftermarket parts, it's essential to ensure compatibility with the specific model and version of the A4VG series pump you are using.
OEM (Original Equipment Manufacturer) parts are manufactured by the same company that produced the original equipment. They are designed to meet the exact specifications and quality standards set by the manufacturer. OEM parts provide the highest level of compatibility and reliability, ensuring optimal performance and longevity. However, they tend to be more expensive compared to aftermarket options.
Aftermarket parts, on the other hand, are manufactured by third-party companies not affiliated with the original equipment manufacturer. These parts are often more cost-effective and readily available. While aftermarket parts may not always match the precise specifications of OEM parts, reputable manufacturers strive to maintain compatibility and quality standards.
When purchasing Rexroth A4VG series parts, whether OEM or aftermarket, it is crucial to consider the following specifications:
Displacement: The displacement range varies across different models of the A4VG series. It determines the amount of fluid the pump can deliver per revolution and affects the overall hydraulic system performance.
Operating Pressure: Each A4VG series pump has a specified operating pressure range. It is essential to select parts that can withstand the required pressure to ensure reliable operation and prevent system failures.
Speed: The maximum speed at which the pump can operate is a critical specification. It determines the pump's efficiency and influences the choice of parts, particularly those related to the drive shaft and bearings.
Material and Construction: The material quality and construction of the parts greatly impact their durability and resistance to wear and tear.
Ensure that the parts you select are made from high-quality materials to withstand the demands of your application.
Compatibility: Whether you choose OEM or aftermarket parts, verify their compatibility with your specific A4VG series model and version. Cross-referencing part numbers and consulting with experts or manufacturers can help ensure the right fit.
