Abstract
A device for pumping fluid has a hydraulic pump ( ) and a drive ( ). The hydraulic pump ( ) is produced as an independent component with different types of drive devices ( ) as additional components that can be coupled in the form of a modular system, and is configured as a coupling piece ( ) for this purpose. Hydraulic tanks ( ) having different volumes represent a third, different type of component. Each hydraulic tank ( ) can be connected on one side to the coupling piece ( ). The corresponding drive device ( ) can be connected on the opposite or same side of the coupling piece ( ). The coupling piece ( ) is built as a single component and embodied in the form of a base plate. The hydraulic pump ( ) is an external gear pump ( ), whose toothed wheels ( ) are received or integrated into the base plate. A compact, modularly constructed building block system is achieved which is functionally reliable and easy to maintain.
