Pump Housing: The pump housing is the main body of the pump and houses all the internal components.

It is typically made of high-quality cast iron or steel to ensure strength and durability. The housing should have precise machining and a robust design to withstand high pressures and loads.

Pistons and Cylinder Block: The A4VG series pumps utilize axial pistons that are driven by a swashplate mechanism. The pistons are usually made of hardened steel or other wear-resistant materials to ensure long life and efficient operation. The cylinder block, where the pistons reciprocate, should also have precise machining and a smooth surface finish to minimize friction and leakage.

Swashplate Assembly: The swashplate assembly is responsible for controlling the displacement of the pump and adjusting the flow rate. It consists of a swashplate, control pistons, and a control cylinder. The swashplate should be made of high-strength materials and have a precise angle adjustment mechanism for accurate displacement control.

Valve Plate and Control Valves: The valve plate is responsible for controlling the flow of hydraulic fluid within the pump. It contains various control valves, including the pressure relief valve, servo valve, and proportional control valve. These valves should be made of high-quality materials and have tight tolerances to ensure proper sealing and smooth operation.

Bearings and Seals: The A4VG series pumps rely on high-quality bearings and seals to minimize friction and prevent leakage. The bearings should be able to handle high loads and rotational speeds, while the seals should provide excellent sealing performance to prevent internal fluid leakage.

Shaft and Drive System: The pump is typically driven by an electric or hydraulic motor through a shaft.

The shaft should be made of high-strength steel and have precise machining to ensure efficient power transmission. The drive system, including couplings and gears, should be reliable and provide smooth operation.

Quality and Compatibility: When purchasing aftermarket parts for the Rexroth A4VG series, it is crucial to ensure that the parts are of high quality and compatible with your specific pump model. Look for reputable suppliers or manufacturers who specialize in hydraulic components and have a track record of providing reliable products.
