Title:
VERMICULARILY ACTING ROLLER PUMP
Document Type and Number:
Japanese Patent JPS6075785
Kind Code:
A
Abstract:
A roller pump (1) comprises a stator member (2) in which a pump bed (3) is formed with specific geometry. In the interior of the pump bed (3) a rotor (6) is rotatably mounted. A pump hose (10) can be inserted into the pump bed (3), said hose being curved in loop-like manner and its two ends being combined in immediate vicinity to each other in a connecting piece (11). The connecting piece (11) can be fixed in location in the stator member (2), the arrangement in the stator member (2) being uniquely defined by cooperation of a location tongue (23) and a location slot (22). Interchanging of the pressure-side and suction-side connection is thus impossible. A holding-down member (24) arranged on the rotor (6) permits automatic insertion and ejection of the pump hose (10) or hose system (9).
