Housing: The pump housing is made of high-quality materials such as cast iron or steel, ensuring durability and resistance to harsh operating conditions.
It provides a rigid structure for the internal components and protects them from external impacts.
Axial Piston Unit: The axial piston unit is a crucial part of the A2FO series pumps. It consists of a cylinder block with several pistons arranged in an axial configuration. These pistons move back and forth within the cylinder block, creating a pumping action.
Pistons: The pistons are precision-engineered components that convert the rotational motion of the drive shaft into linear motion. They are typically made of high-strength materials such as steel or ceramic to withstand high pressure and ensure long service life.
Swash Plate: The swash plate is responsible for controlling the stroke and displacement of the pistons. It is mounted at an angle to the drive shaft and can be adjusted to vary the pump's output flow. The swash plate angle determines the pump's displacement, allowing for variable flow control.
Bearings: The A2FO series pumps are equipped with high-quality bearings to support the rotating components and minimize friction losses. These bearings are designed for high-speed operation and provide smooth and reliable performance.
Shaft Seal: The shaft seal ensures a leak-free operation by preventing the fluid from escaping along the drive shaft. It is typically a combination of seals and o-rings that maintain a tight seal between the rotating shaft and the stationary housing.
Control Devices: The A2FO series pumps can be equipped with various control devices to optimize their performance and meet specific application requirements. These control devices include pressure relief valves, flow control valves, and load-sensing mechanisms. They enable precise control of the pump's output and protect the system from overpressure conditions.
Ports and Connections: The pump features inlet and outlet ports for fluid flow, as well as connections for mounting and integrating into hydraulic systems.
These ports and connections are designed to ensure proper fluid routing and facilitate easy installation and maintenance.
Filtration: To maintain the cleanliness of the hydraulic system, the A2FO series pumps can be equipped with optional filtration elements. These filters prevent contaminants from entering the pump and other system components, thereby ensuring reliable operation and prolonging the service life of the pump.
Optional Accessories: Rexroth offers a range of optional accessories and configurations for the A2FO series pumps. These include different mounting flanges, shaft options, and various control options. These accessories provide flexibility and customization to meet specific application requirements.
