The A4FO Rexroth hydraulic pump series is part of the broader A4FO product family.
These pumps are characterized by their axial piston design, which enables variable displacement and precise control over hydraulic flow and pressure. They are available in various displacements, including 022, 028, 071, 125, 180, 250, and 500cc/rev, catering to a wide range of application requirements.
Design and Construction:
The A4FO pumps are meticulously engineered and constructed to withstand demanding operational conditions. They feature a swashplate design, where the angle of the swashplate determines the displacement and, consequently, the flow rate of the pump. This design ensures efficiency and adaptability to changing load requirements.
Operating Principle:
These pumps operate on the axial piston principle. When pressurized fluid is introduced into the pump's housing, it acts on the pistons, causing them to move axially. As the pistons reciprocate, they create a pumping action, drawing in and pressurizing hydraulic fluid. The variable swashplate angle regulates the piston stroke and, consequently, the flow of hydraulic fluid.
Variable Displacement:
One of the standout features of the A4FO series is its variable displacement capability. Operators can adjust the swashplate angle either manually or electronically to control the output flow and pressure precisely. This flexibility enhances system efficiency and reduces energy consumption by matching the pump's output to the actual requirements of the system.
Efficiency and Performance:
These Rexroth pumps are engineered for high efficiency.
They are capable of providing consistent performance across a wide range of operating conditions. Reduced internal leakage, advanced materials, and precision manufacturing contribute to their excellent performance.
Versatility:
The A4FO series offers versatility in terms of mounting options, shaft configurations, and control methods. This adaptability makes it suitable for a broad spectrum of applications, from mobile equipment like excavators and agricultural machinery to industrial processes such as injection molding and metal forming.
Control Options:
A4FO pumps can be integrated with various control mechanisms, including manual, hydraulic, and electronic controls. This allows for precise adjustment of flow and pressure, which is essential in applications where dynamic control is crucial.
Durability and Reliability:
Rexroth is known for manufacturing rugged and dependable hydraulic components, and the A4FO series is no exception. These pumps are designed to withstand harsh environments and heavy usage, contributing to their long service life and low maintenance requirements.
