Pump, particularly internal- or external gear pump, vane pump, axial piston pump or radial piston pump, has data store, in which characteristic curve indicating relationship between speed of drive shaft and fluid flow of pump is stored

摘要

The pump has a rotatable drive shaft and a suction- and pressure connection, where a fluid flow from the suction connection to the pressure connection is effectuated by the rotation of the drive shaft. The pump is provided with a data store, in which a characteristic curve is stored, which indicates the relationship between the speed of the drive shaft and the fluid flow of the pump. The data store is a bar code or a matrix code, which is mounted on the outer surface of the pump. The pump has a constant displacement volume.
