A11VO Series Axial Piston Variable Pump

Introductions

A11VO Series pumps convert mechanical input power into controlled hydraulic flow through an axial piston rotary group arranged in swashplate design. By changing the swashplate angle, the pump displacement can be varied continuously, allowing the output flow to be adapted to changing machine demand. This variable-displacement principle supports efficient hydraulic system operation and makes the pump suitable for applications requiring controlled flow, pressure or power management.

Key Features

• Variable displacement axial piston pump with swashplate construction.

• Designed for open-circuit hydrostatic and hydraulic power systems.

• Flow varies with pump displacement and drive speed for flexible system control.

• Multiple control configurations are available to match different machine requirements.

• Compact design with high power density for mobile and industrial installations.

• Available in multiple nominal sizes and connection configurations, depending on series and version.

• Through-drive options are available on many configurations for tandem pump arrangements.

• Suitable for replacement, maintenance and new hydraulic system projects when the full model code is correctly matched.

Typical Applications

Typical applications include excavators, loaders, cranes, agricultural machinery, drilling equipment, mining machinery, road construction equipment, material handling systems and other mobile or industrial hydraulic machines requiring adjustable pump flow and dependable pressure supply.

Common Size Range

Common A11VO Series 1 configurations include nominal sizes such as 40, 60, 75, 95, 130, 145, 190 and 260 cm³/rev. Actual available sizes, controls, ports, shafts, mounting flanges and through-drive combinations depend on the exact series and model code.

Configuration & Selection

For correct pump selection or replacement, confirm the complete A11VO model code together with nominal size, rotation direction, control type, shaft end, mounting flange, working ports, pressure requirements, speed range, through-drive option and machine application. Because different A11VO variants can differ in dimensions, control characteristics and interfaces, full model-code matching is recommended before ordering.
