摘要

The pump (1) has two pump bodies (3, 5) provided for conveying liquid, where the pump bodies are fastened to respective drive shafts (A, B) inside a pump housing (2). Drives (4, 6) are connected to the respective shafts for rotatably driving the respective bodies. The pump bodies are coaxially arranged one behind the other in the housing. The driving shafts are arranged concentrically to each other, where one of the driving shafts (A) runs inside the other drive shaft. A sensor detects weight and/or volume and/or fuel level and/or filling duration of delivered conveying amount of the pump. Independent claims are also included for the following: (1) a method for controlling a hose pump (2) a filling device comprising a sensor.
