China iron A4VTG Series Rexroth Hydraulic Pump Spare Parts Replacement | Tonkee®

The A4VTG series pumps are known for their variable displacement capability, allowing for adjustable flow rates to meet specific system requirements.

These pumps feature a swashplate design, where the angle of the swashplate determines the pump's displacement. This design enables the A4VTG series to deliver a constant flow at variable speeds, making them suitable for a wide range of hydraulic applications.

One essential spare part for the A4VTG series is the swashplate itself. The swashplate is a critical component responsible for converting the rotating motion of the pump shaft into axial piston movement. When replacing the swashplate, it's crucial to ensure that the replacement part meets the manufacturer's specifications in terms of material quality, dimensions, and surface finish. This ensures proper alignment and functionality within the pump assembly.

Another vital spare part is the axial piston, which directly interacts with the swashplate to generate fluid flow.

These pistons experience significant wear and tear over time, especially in high-demand applications. Replacement pistons must match the original specifications to maintain the pump's efficiency and performance. Material composition, surface hardness, and precision machining are essential factors to consider when selecting replacement axial pistons.

Seals and gaskets are critical spare parts that contribute to the A4VTG series pumps' reliability by preventing fluid leakage. These seals are exposed to hydraulic pressure and temperature variations, making them susceptible to deterioration over time. When replacing seals and gaskets, it's imperative to choose materials that can withstand the specific conditions of the hydraulic system, ensuring a proper seal and preventing any potential leaks.

Bearings and bushings are also crucial components in the A4VTG series pumps. These parts support the rotating elements within the pump and are subject to friction and wear. Replacement bearings and bushings should meet or exceed the original specifications to maintain proper clearances and prevent premature failure.
