<p>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. <IMAGE></p> |
