Abstract

Peristatic pump, which is especially applicable to monochromators, and of the type that incorporate a rotor, driven by the corresponding motor, in which a plurality of rods are established on which rests, with a semicircunferencial trajectory banked, the flexible conduit of fluid transport, defining for said conduit zones of punctual throttling in correspondence with such rods essentially characterized in that it is constituted from a base body, generally cylindrical affected by a wide perimeter groove preferably of u-section, which defines in said body two extreme discoidal flanks, one of said flanges being provided on its internal face, with a circumferential alignment of blind holes, uniformly distributed, while the other is in turn affected by respective holes, now through, operatively facing the former, each pair of holes facing each other tined to receive a rod, with freedom of rotation to which effect the diameter of the latter is slightly smaller than that of such holes, and complementing this set with a discoidal and flattened cover, designed to adapt to the external face of the flange, carrier of the through holes and acting as axial retainer for said shanks, covers that is fixed properly to the base body.
