HOSE RECEPTACLE OF A ROLLER PUMP

摘要

A peristaltic pump includes a housing in which a tube mounting case is formed in which a pump head is rotatably supported. The pump includes a tube unit provided as a replacement part consisting of a flexible tube and a tube fixture which holds the tube at two positions. The tube unit is insertible in the tube mounting case so that by displacing the tube fixture, the tube enters into tensioning engagement with the pump head. A tensioning device is arranged on the housing or on the tube mounting case in the form of a lever mechanism for tensioning displacement of the tube fixture by at least one lever element. A locking or clamping mechanism forms an undercut which upon reaching a tube tensioning position engages in a counter-locking/clamping mechanism arranged on the tube fixture for locking the tube fixture and the tensioning device in the tube tensioning position.
