Hydraulic A11V(L)O Axial Piston Variable Pump
An axial piston pump with a variable displacement is the A11V (L) O pump. This unit employs a swashplate design for open circuit hydrostatic drives and is mostly intended for mobile applications.
Below are the sizes in which this pump can be found: 40, 60, 75, 95, 130, 145, 190 and 260 cc/rev The nominal pressure of this pump is 350 bar while its peak pressure reaches up to 400 bars.
The flow rate is directly proportional to both drive speed and displacement; therefore by altering the angle of inclination on the machine’s plate (swashplate), flow rates can be changed infinitely or without causing any tension at all.

General Installation Notes for A11V Series Pumps
Hydraulic Fluid and Venting: When commissioning or operating the axial piston unit, ensure that hydraulic fluid is filled into it and vented. This is necessary because even during longer standstills, the unit can self-empty through the hydraulic lines.
Leakage Management: Ensure that leakage in the housing area is directed to the reservoir via the highest drain port (T1/T2). For combination pumps, each single pump’s leakage must be drained off. Where a common drain line is used, do not exceed the respective case pressure in each unit. Size the shared drain line such that the maximum permissible case pressure of all connected units is not exceeded under any operating condition, especially during a cold start.
Noise Reduction: Decouple all connecting lines from vibration-capable components (e.g., reservoirs and frame parts) by means of elastic elements to prevent the transmission of structure-borne noise.
Suction and Drain Lines: The suction line and drain line must lead to the reservoir below the minimum fluid level at any operational state. The allowable suction height results from the total pressure loss but should not exceed 800 mm. During operation, the minimum suction pressure at port S = 0.8 bar absolute (without charge pump) or 0.6 bar absolute (with charge pump) must not be fallen below.
Reservoir Design: Ensure sufficient distance between the suction line and drain line. A baffle plate improves air separation by affording more time for desorption to the hydraulic fluid, lowering temperature backflow into the heated return flow drawn directly back into the suction line. Supply air-free, calmed, cooled hydraulic fluid through the suction port.
Installation Positions
Below-Reservoir Installation: Install the axial piston unit outside the reservoir below the minimum fluid level; bleed air properly when filling in this position to avoid dry running.
Above-Reservoir Installation: Install the axial piston unit above the minimum fluid level of the reservoir; require a 25 mm height difference at port R in position 7 to prevent draining. A check valve in the drain line can prevent housing area draining. The minimum displacement setting must be Vg ≥ 5% Vg max for certain control options. Observe the maximum permissible suction height of 800 mm.
Inside-Reservoir Installation: Install the axial piston unit in the reservoir below the minimum fluid level. Do not install axial piston units with electric components in a reservoir below the fluid level unless medium compatibility is confirmed.
