Rexroth A11VO Series 1x Axial Piston Pump With Swash Plate For Excavators

In the operation of excavators, actions such as the lifting of the boom, the digging of the bucket, and the rotation all rely on the stable power output of the hydraulic pump. The Rexroth A11VO Series 1x Axial Piston Pump With Swash Plate is specially designed for excavators and is a core component integrating power and precise control. As a professional axial piston pump with swash plate, it achieves flexible adjustment of flow rate through the swash plate structure and can perfectly adapt to the complex and changeable working conditions of excavators - whether it is the powerful output during heavy-load excavation or the smooth control during fine operations, it can handle them with ease. ​
The rexroth A11VO series pumps, relying on Bosch Rexroth's century-old hydraulic technology accumulation, perform exceptionally well in terms of reliability and efficiency. Its structural design fully takes into account the working environment of excavators, capable of withstanding vibration, dust and temperature differences, providing long-lasting and stable hydraulic power for excavators of various brands, and has become a highly trusted power solution in the industry. ​

The swash plate structure is enhanced, ensuring precise and controllable power

The core advantage of axial piston pump with swash plate lies in the synergy between the swash plate and the plunger: a slight change in the swash plate Angle can achieve stepless adjustment of the flow rate, and the response time is only 0.15 seconds. When the excavator performs fine operations (such as slope trimming), the rexroth a11vo pump can fine-tune the output of a small flow rate through the swashplate to ensure that the bucket movement is precise to the centimeter level. When switching to heavy-load excavation, the inclined plate quickly adjusts to the maximum Angle, instantly outputting the maximum flow rate, and the excavation force increases by 10%. This "on-demand adjustment" feature enables excavators to be both efficient and energy-saving in various operations. ​
Meanwhile, the contact surface between the swash plate and the plunger adopts mirror grinding technology, combined with a self-lubricating design, reducing the friction coefficient to 0.01. This not only reduces energy loss but also significantly enhances the wear resistance of the components. During the daily 10-hour continuous operation of the excavator, the pump body temperature remains stable within 60℃, and the operating noise is 5-8dB lower than that of ordinary pumps, creating a more comfortable environment for the operator. ​

Original factory compatibility, reliable and durable

The rexroth A11VO is tailor-made for the hydraulic systems of excavators. Its key dimensions and installation interfaces are perfectly matched with mainstream excavator models, such as those in the 20-30 ton class. The pump body is made of high-strength cast iron. After nitriding treatment, the surface hardness reaches HV700, which can withstand the severe vibration (vibration acceleration ≤10g) and impact load during excavator operation. The core components such as the plunger and the distribution plate are made of wear-resistant alloy materials. In a dusty construction site environment, their service life is 40% longer than that of ordinary pumps. ​
The sealing system of a11vo pump is equally excellent. It adopts high-pressure resistant fluororubber seals, which have no leakage at the rated pressure of 350bar and can adapt to temperature changes from -30 ℃ to 100℃. Even in extremely cold mines or hot tropical construction sites, it can maintain stable performance and reduce downtime caused by seal failure. ​

Earthwork operation

In earthwork operations such as foundation excavation and site leveling, the rexroth a11vo pump demonstrates strong adaptability. When the excavator alternates between excavation and relocation actions, axial piston pump with swash plate can adjust the flow rate in real time - output a large flow rate during excavation to ensure power, reduce the flow rate during relocation to reduce energy consumption, and save 8-12 liters of fuel in a single shift operation.

​
Heavy-duty crushing

Excavators equipped with breakers need to perform high-frequency impact operations. The rexroth A11VO can provide a stable high-pressure oil source and ensure uniform hammer strike frequency (up to 600 times per minute) through the rapid response of the swash plate. Its anti-impact design can absorb the reaction force during breakage, prevent the pump body from being damaged by high-frequency vibration, and extend the overall service life of the equipment. ​

Fine work

In the meticulous operations such as pipeline excavation and green belt renovation in municipal engineering, the precise control feature of a11vo pump highlights its advantages. The flow rate changes slightly through the swash plate adjustment, ensuring smooth lifting and rotating movements of the bucket without impact, avoiding damage to surrounding facilities, and enhancing the safety and accuracy of the operation.
