Model: A7VO28
Type: The A7VO Rexroth hydraulic pump is an axial – piston variable – displacement pump. It is designed to provide reliable hydraulic power for various applications such as construction machinery, agricultural equipment, and industrial hydraulic systems.
Performance Specifications
Displacement
The displacement of the A7VO28 pump is 28 cm³/rev. This indicates the volume of hydraulic fluid that the pump can displace in one complete revolution of its shaft.
Pressure
Presiune nominală: The pump typically has a rated pressure of around 350 bar. This is the normal operating pressure at which the pump is designed to function efficiently and reliably.
Presiune maximă: It can withstand a maximum pressure of up to 400 bar. Cu toate acestea, continuous operation at the maximum pressure may affect the pump's lifespan and performance.
Speed
Maximum Rotational Speed: The maximum rotational speed of the pump at maximum displacement is approximately 2200 – 2500 rpm. This speed limitation is crucial to prevent over – speeding – related problems such as excessive wear, vibration, and decreased efficiency.
Minimum Rotational Speed: There is a minimum rotational speed, usually around 500 – 800 rpm. Below this speed, the pump may not be able to generate sufficient pressure or flow rate for the hydraulic system.
