Competitive Advantages
 

1. This AA11VLO130DRS10R-NSD62N00 (R909609230) axial piston variable pump adopts DRS constant power plus pressure cut-off control. It can automatically adjust displacement according to load changes, match engine power output, effectively avoid system overload, and deliver stable hydraulic power even under heavy and fluctuating working conditions.

2. Equipped with an integrated built-in charge pump, this A11VLO series pump simplifies the whole hydraulic system layout. It supplies stable oil replenishment for the open circuit system, maintains low suction pressure, reduces cavitation risk, and brings a more compact installation structure for mobile construction machinery.

3. Made of high-strength cast iron housing and precision ground internal piston components, this R909609230 hydraulic pump features strong wear resistance and shock resistance. It works reliably under high pressure 350bar nominal / 400bar peak pressure, extending service life in harsh outdoor construction and mining environments.

The Analysis for Rexroth A11VOL Axial Piston Pump Commom Breakdown:

1. Insufficient output flow or weak machine action. This issue is usually caused by worn piston and valve plate inside the pump, or insufficient oil supply from the built-in charge pump. It will lead to slow movement of actuators and reduced working efficiency of the whole hydraulic system.

2. Abnormal noise and vibration during pump operation. Cavitation due to blocked suction filter, low oil level or oil contamination are the main causes. Long-term noisy operation will accelerate wear of bearing and swashplate, and may further damage related hydraulic components.

3. Pressure failure or unstable system pressure. It often comes from failure of the DRS control regulator, internal leakage of sealing parts, or stuck valve components. The pump cannot build up rated pressure, resulting in inability to lift heavy loads or fluctuating pressure during operation.
