Axial Piston Unit:
The heart of the Rexroth A2FO pump is the axial piston unit, which consists of a set of pistons arranged in a circular pattern within a cylinder block.

These pistons are responsible for generating the hydraulic pressure required for pumping fluid. The A2FO Series offers different displacement options to suit specific flow and pressure requirements.

Drive Shaft:
The drive shaft connects the axial piston unit to the drive mechanism of the machine. It transfers the rotational force from the prime mover to the pump, enabling the conversion of mechanical energy into hydraulic power.

Swash Plate:
The swash plate is a key component that converts the rotating motion of the drive shaft into reciprocating motion of the pistons. By tilting the swash plate, the operator can control the displacement and, consequently, the flow rate of the pump.

Valve Plate:
The valve plate regulates the flow of hydraulic fluid into and out of the piston chambers. It contains various valves, such as the inlet and outlet valves, which ensure proper fluid direction and prevent backflow.

Cylinder Block:
The cylinder block houses the piston chambers and provides the necessary guidance for the axial movement of the pistons. It is precision-machined to ensure smooth operation and tight tolerances for optimal performance.

Port Plates:
Port plates serve as the interface between the cylinder block and the hydraulic system. They contain the inlet and outlet ports that allow fluid to enter and exit the pump. Port plates are designed to provide reliable sealing and minimize leakage.

Bearing and Sealing Elements:
The A2FO Series utilizes high-quality bearings and sealing elements to reduce friction, extend service life, and maintain system efficiency.

These components are crucial for preventing fluid leakage and ensuring smooth operation under various operating conditions.

Control Options:
Rexroth A2FO pumps offer various control options to meet specific application requirements. These may include manual control, hydraulic control, or electro-hydraulic control, allowing for precise control over pump displacement and flow rate.
