A medical peristaltic pump having improved pumping and sealing qualities, as well as providing increased flexibility of use and a high level of security. The pump is assembled from at least three modules, a pump rotor (22) being housed in a first module (36; 172) for compressing at least one tube (28; 28a; 28b) connecting a reservoir (30) for storing a liquid substance to the output (32) of the pump. The compression is effected against at least one support piece (34) of a second module (38, 174). The first and second modules are provided with first positioning elements and first assembly elements in a manner to define a set of two modules for compressing the tube to pump the liquid substance. The set of two modules and a third module (40, 176) are provided with second positioning elements and second assembly elements in a manner such that, once assembled, the third module (40, 176) assures sealing of the first module.
