Abstract

The invention relates to a peristaltic pump in which a case is formed by a dimensionally stable supporting frame ( 1 ) and by a tube reception device ( 2 ) formed thereon by clipping. A rotor ( 3 ) provided with three rotatable transport rollers ( 33 a , 33 b , 33 c). Said tube reception device ( 2 ) is provided with a tube bearing body ( 25 ) which forms a bed for the tubes on the internal surface and comprises two legs ( 2 a , 2 b) on the ends thereof. The tube flexible sections ( 43 ) are compresses by said transport rollers ( 33 a , 33 b , 33 c) in order to ensure the peristaltic conveyance of a medium. The two legs ( 2 a , 2 b) are elastically deformable in a radial direction in order to be elastically adaptable on the supporting frame ( 1 ). The bearing body ( 25 ) is substentially omega-shaped and provided with uniform input and output areas which ensure a medium continuous low-pulsed peristaltic conveyance. The inventive pump is constructed in such a way that it is small-sized, comprises few spare parts and is rapidly and easily mounted.
