Abstract
A peristaltic pump comprises a housing (2) in which a peristaltic action is applied to a tube (6) by a rotor (4). The tube (6) has locating means in the form of flanges (16) at each end, which ensure proper positioning of the tube (6) within the housing (2). The housing (2) makes a fluid-tight seal with the flanges (16) so that the interior of the housing (2) is isolated from the ambient surroundings. The flanges (16) are non-circular and fit in complementary recesses (30), (32) in the housing (2) so that, when installed, the tube (6) is not twisted between its ends.
