product description 


The BOSCH REXROTH AA4VSO250DR/30R-FPB13N00E is an axial piston pump 

that uses the variable pump A4VSO 250cm³/U.


A4VSO is a common axial piston pump model, where A4 indicates the pump series, 

VSO indicates the variable displacement axial piston pump, 250 indicates the displacement 

of 250 cm³/rev (displacement per revolution), and U indicates the safety protection function.


Axial piston pump is a kind of pump that transfers liquid through the reciprocating movement 

of the plunger in the cylinder, which is widely used in the occasions of high pressure, large 

flow rate, high precision and large conveying viscosity. This type of pump usually has a high 

working pressure and flow regulation range, which can meet the needs of different application 

scenarios.


It should be noted that the specific model and parameters may vary according to different 

manufacturers and application scenarios, it is recommended that you read the product manual 

carefully before use or consult a professional to ensure correct use.


Axial piston pump is a kind of hydraulic element that uses the reciprocating movement of the 

plunger in the cylinder to produce pressure. The plunger pump has a variety of variable situations 

to meet the different needs of users.


The advantages of axial piston pump include simple structure, small size, low noise, high efficiency,

 long life and self-priming ability. In addition, the pump adopts the optimal oil film thickness design 

for hydraulic static balance, so that the cylinder block and the oil distribution disc, the slipper and 

the variable head are operated under pure liquid friction, which has a high working efficiency and 

reliability.


The disadvantages of axial piston pumps include higher requirements for the cleanliness of hydraulic 

oil, and if the hydraulic oil contains impurities or particles, it will accelerate the wear of the plunger and 

cylinder block, resulting in leakage and performance degradation. In addition, the temperature and 

viscosity changes of hydraulic oil are more sensitive, with the change of temperature and viscosity, 

the density and viscosity of the oil will change, affecting the normal operation of the pump.


Axial piston pump is widely used in machine tools, forging, metallurgy, engineering, mining, ships and 

other machinery and other hydraulic transmission systems.
