A2FO Hydraulic Gear Pump Thrust Plate

A2FO Hydraulic Pear Pump Overview

A2FO Hydraulic Pear Pumps are engineered for high efficiency, stable pressure control, and long service life. Designed with a pressure-compensated variable displacement mechanism, these pumps automatically adjust output flow according to system demand, making them an ideal solution for modern energy-saving hydraulic systems.

Features and Benefits

• Axial Piston Design: The A2FO features an axial piston design, which is known for its high efficiency, variable displacement, and high power density. It uses a swash plate mechanism to change the piston stroke, providing precise control of the pump’s output flow and pressure.

• Variable Displacement: The pump has variable displacement, meaning it can adjust its output flow rate in response to changing system demands. This feature is critical for systems that need to operate under varying loads and conditions, such as construction machinery or mobile equipment.

• Efficiency: With its variable displacement design, the A2FO pump adjusts flow to suit the specific needs of the system, ensuring optimal energy usage.

• High Performance: Capable of delivering high power at high efficiency, even under heavy loads and high-pressure conditions.

FAQ

1.How does the variable displacement work?

The pump's flow is adjusted by changing the angle of an internal swash plate. As the swash plate angle changes, the stroke length of the pistons varies, which in turn changes the volume of fluid displaced per rotation, allowing the flow rate to adapt to the system's needs.
