Open the catalog to page 2Overview variable displacement axial piston pump type C40V Variable displacement axial piston pumps adjust the geometric output volume from maximum to zero. As a result they vary the ow rate that is provided to the consumers. The variable displacement axial piston pump type C40V is designed for open circuits in mobile hydraulics and operates according to the swash plate principle. The range of pump controllers allows the axial piston pump to be used in a variety of applications. Features and advantages ■ Optimized power-to-weight ratio ■ Broad selection of controllers ■ Thru-shaft...

Open the catalog to page 62.2.1 Load-sensing controllers LS0DA/LS2DA The LS0DA, LS2DA controllers are ow controllers that generate a variable, speed-independent ow rate. They adapt the displacement volume of the pump to the required ow rate of the consumer and regulate a constant difference between load pressure and pump pressure. The integrated pressure limitation restricts the maximum pressure to a set value.

Open the catalog to page 82.2.2 Load-sensing controllers LS0DE.. / LS2DE.. The LS0DE.. LS2DE.. controllers are a combination of load-sensing controller and electro-proportional pressure controller. They are typically used to simultaneously supply the working functions and the fan with a pump. The load-sensing controller (LS) generates a variable ow rate independently of the speed. It adapts the geometric displacement of the pump to the required ow rate of the consumer and regulates a constant difference between load pressure and pump pressure. The DE.. controller regulates the pump pressure on the basis of an...

Open the catalog to page 112.2.3 Pressure controller DF-DA The DF-DA controller consists of two parts. The ‘DA’ part is responsible for setting the maximum pressure. As soon as the pump pressure exceeds the set value, they reduce the swivel angle of the pump and regulate a constant pressure level. The pressure setting is adjusted using an adjusting screw on the controller, and, in addition, an external pilot valve can be connected to the X5 port to enable remote adjustment when necessary. If an external pressure-limiting valve has been connected to the X5 port, the ‘DF’ part will regulate a constant pressure level...
Open the catalog to page 122.2.4 Pressure controller DE.. The DE controller is an electro-proportional pressure controller. As soon as the pump pressure exceeds the set value, the controller reduces the swivel angle of the pump and regulates a constant pressure level. The minimum and maximum pressures are set mechanically on the controller. In between these values, the pressure can be adjusted proportionally using an electrical signal. Solenoid voltage and version: see Chapter 2.3, "Solenoid voltage and version" DE1/3/5/7 (rising characteristic line) DE2/4/6/8 (falling characteristic line) Characteristic lines...
