Abstract (en)
[origin: EP0947698A2] The channel (13) is provided with a detector device, preferably a pressure sensor or conductivity sensor, for conveyed material within it. The hose (1) has at least one coupling and the channel in the area of the coupling extends out of the hose. The hose pump has a housing (2,6,7) with a suction connection. The at least one hose, which is connected both to the pressure and suction connections, locates on the inner wall of the housing. The hose pump has at least one squeeze body (3) which is so moved along the hose that the hose is squeezed together by each squeeze body out of the direction of the suction connection into that of the pressure connection. The hose has an inner core (12), a cover (10) and a reinforcement (11) between them.
