Control unit

LR – Power Control
The power control regulates the displacement of the pump depending on the operating pressure so that a given drive power is not exceeded at constant drive speed.

LRC Override with cross sensing
Cross sensing control is a summation power control system, whereby the total power, of both the A11VO and of a same size A11VO power controlled pump mounted onto the through drive, are kept constant.

LR3 High-pressure related override
The high-pressure related power override is a total power control in which the power control setting is piloted by the load pressure of an attached fixed pump (port Z).

LG1/2 Pilot-pressure related override
This power control works by overriding the control setting with an external pilot pressure signal. This pilot pressure acts on the adjustment spring of the power regulator via port Z.

Features

– Variable axial piston pump of swashplate design for hydrostatic drives in open circuit hydraulic system.

– Designed primarily for use in mobile applications.

– The pump operates under self-priming conditions, with tank pressurization, or with an optional built-in charge pump (impeller).

– A comprehensive range of control options is available matching any application requirement.

– Power control option is externally adjustable, even when the pump is running.

– The through drive is suitable for adding gear pumps and axial piston pumps up to the same, i.e. 100% through drive.

– The output flow is proportional to the drive speed and infinitely variable between qV max and qV min = 0.
