Core features

• Design structure: It uses an inclined-axis (bent-axis design) axial tapered piston rotor group. The piston end is equipped with a slipper, which is pressed against the swash plate by a spring. It cooperates with the spherical oil distribution disc to achieve automatic centering and reduce frictional losses.

• Operating range:Displacement specifications: It covers 5 - 1000 cm³/rev. Common specifications include A2FO10, A2FO23, A2FO90, etc..

• Pressure performance:The rated pressure can reach up to 400 bar (350 bar for some specifications from 250 - 1000). The peak pressure can reach 450 bar..

• Speed capability:The maximum speed range is 1450 - 6000 rpm. The flow rate is proportional to the driving speed and displacement..

• Key advantages:High efficiency: The volumetric efficiency is about 95%, and the total efficiency is about 90%. It operates smoothly and has low noise..

• Long lifespan:The drive shaft bearings are specially designed for heavy loads. Some specifications (250 - 1000) use long-life bearings..

• Economy:It has a sealed piston ring design, resulting in lower maintenance costs.

• Application fields

• Applicable scenarios: Construction machinery (such as concrete pump trucks, road rollers), industrial equipment (machine tools, hydraulic presses), mining and ship systems, etc..

• Operating requirements:Hydraulic oil: L-HM32 - 68 anti-wear hydraulic oil is recommended. The cleanliness needs to be controlled within NAS10 level..Safety regulations: The oil should be kept clean, replaced regularly (1000 - 3000 hours), and an overflow valve should be installed to protect the system
