Product Description

The A2FO series pumps are high - performance fixed-displacement axial-piston pumps with a bent-axis design. They are widely used in various industrial fields and mobile machinery.
 

 

Structural Characteristics
The pump is equipped with an axial-conical-plunger rotor group with a bent-axis design. The pistons are arranged diagonally with respect to the drive shaft. This structure enables smooth fluid flow, low vibration, and low noise during operation.
 
Working Principle
The drive shaft rotates to make the pistons in the cylinder block move back and forth along the axial direction under the action of the inclined - axis mechanism, thereby achieving the suction and discharge of hydraulic oil. The output flow is proportional to the drive speed and displacement.
 
Performance Characteristics
- High Efficiency: The slanted-shaft design has high transmission efficiency, which can effectively reduce energy loss.
- High Pressure Resistance:The nominal pressure can reach up to 400 bar, and the peak pressure can reach up to 450 bar.
- Wide Displacement Range:The displacement range is from 5 to 1000 cm^{3}/rev, which can meet the requirements of different hydraulic systems.
- Good Reliability: High-quality materials and manufacturing processes are adopted, which have high reliability and durability.
