A PERISTALTIC HOSE PUMP

摘要

The hose pump comprises an eccentric drive with numerous eccentric discs (21) fastened to a shaft (20). Each eccentric disc (21) drives a crank drive (24) with a connecting rod (25). At the end of the connecting rod (25), a pump finger (11) is borne which compresses a pump hose (10). A sealing diaphragm (27) preventing liquid from intruding into the interior of the housing (16) is disposed between the eccentric drive and the pump hose (10). The sealing diaphragm (27) comprises lateral folds (31) so that it does not exert any substantial forces upon the crank drive (24). The hose pump has a iow power consumption and permits a small structure.
