A11VO 75/130/145/190/260 Series Axial Piston Pumps For Mining Equipment

 A11VO 75/130/145/190/260 Series Axial Piston Pumps For Mining Equipment

1,Product Introduction

The A11VO 75/130/145/190/260 is a high-performance, swashplate-type axial piston variable displacement pump manufactured by Bosch Rexroth, primarily designed for open circuit hydraulic systems. Renowned for its exceptional efficiency, high power density, and reliability, it is a widely used and classic pump model across various industries including industrial machinery, mobile equipment, and marine applications.

2,Key Features 

. Variable Displacement: The core feature is its ability to vary the displacement. Through built-in control systems (e.g., pressure control, power control, electronic control), the pump automatically adjusts the swashplate angle to change the output flow according to system demands, enabling energy savings and precise control.
. High Operational Efficiency: Incorporates advanced technologies such as optimized piston and slipper design and a pressure-compensated swashplate, resulting in high volumetric and overall efficiency, which effectively reduces energy consumption and oil heating.
. Long Service Life and Reliability: Robust construction, high-quality bearings, and friction pair materials ensure extremely long service life and high reliability even under harsh operating conditions.
. Multiple Control Options: Offers a wide range of control options to meet diverse application needs:
· Pressure Control: e.g., Constant Pressure Control (CP), where the pump reduces displacement to maintain a set pressure when reached (common model: A11VO LRDS).
 · Electronic Control: e.g., Proportional Electro-magnetic Control, allowing infinite adjustment of displacement via an electrical signal for intelligent control (common model: A11VO EP).
. Low Noise Operation: Features optimized port plate designs and noise reduction technologies for smooth and quiet operation.

3,Typical Applications

· Mobile Machinery: Excavators, concrete pump trucks, cranes, loaders.
· Industrial Hydraulic Systems: Injection molding machines, presses, machine tools.
· Marine Equipment: Steering gears, winches, deck machinery.
· Other Mobile Equipment.

4, Frequently Asked Questions (FAQ)
· Q: What are the main differences between A7VO piston pump and A10VO/A11VO piston pump?
· A: A7VO 75/130/145/190/260 is a variable displacement pump in the medium to heavy-duty series, characterized by its constant power control and high power density, commonly used in mobile machinery. A10VO/A11VO are more inclined towards industrial applications, with different design focuses and pressure and displacement ranges.
