Product Introduction
ATUS A11V (A11VO/A11VLO) series swash‑plate variable displacement axial piston pump is designed for heavy‑duty open‑circuit hydrostatic transmission systems. High power density and multiple control options make it a reliable drop‑in replacement for mobile construction and mining machinery. Displacement ranges from 40cc to 260cc/rev, A11VO version equipped with built‑in charge pump for higher speed operation

Nominal Pressure: 350 bar
Peak Pressure: 400 bar
Circuit Type: Designed for open-loop hydraulic systems
Application: Primarily used in hydraulic systems of mining machinery, engineering machinery, ships and other equipmentmobile equipment and tunneling machines
Features
Swash‑plate variable displacement structure, flow stepless adjustable from zero to maximum
Nominal pressure 350bar, peak pressure up to 400bar for heavy‑load working conditions.
100% through‑shaft drive, supports tandem installation of gear pump or second piston pump.
Multiple control modes available: load‑sensing, pressure‑limiting, electro‑hydraulic, constant‑power control
Constant‑power control can be adjusted externally even while pump is running
A11VO variant with built‑in charge pump, supports higher rotational speed and self‑priming operation
High volumetric and mechanical efficiency, low energy consumption and heat generation
Heavy‑duty cast iron housing, robust bearing assembly for long service life
Standard SAE mounting flange, fully interchangeable with original units
Complete spare parts for on‑site maintenance and repair
Control Methods:
Power control (with various options, externally adjustable during operation)
Pressure control
Hydraulic control (based on pilot pressure)
Electrical control (with proportional solenoid valves)
Various customizable control combinations
Advantages:
Output flow is directly proportional to drive speed and pump displacement.
Stepless flow regulation can be achieved easily by adjusting the swashplate angle between qV max and qV min = 0.
Excellent oil suction characteristics and low operating noise levels.
100% through-shaft driven capability, perfectly suitable for connecting additional gear pumps or axial piston pumps.
Application Range
Concrete pump trucks, excavators, rotary drilling rigs, road rollers, pavers, mining machinery, underground mining vehicles, port equipment, heavy‑duty mobile hydraulic systems.
