FIELD OF THE INVENTION [0001] The present invention refers to a pump with progressive vortex system. DESCRIPTION OF THE RELATED ARTS [0002] The current pump systems are composed of the so-called helical progressive cavity pumps. These pumps have a rubber stator with a single cavity. This cavity has a helical shape generated by two 180.degree.-dephased circumferences (double entry) that are displaced with a determined pace along the central stator shaft. The helical rotor as it rotates inside this cavity has an inevitable radial displacement. Therefore, these pumps need a compensation system in the rotation movement transmission, generally performed by a cardan shaft. Although the problem in the transmission is solved, these pumps have the inconveniences of having great lengths, in function of the cardan, and of working with an undesirable vibration. This vibration most of the time hinders these equipments to work with rotations greater than 500 rpm. [0003] Another system currently used is based on the axial flow of the fluid through multiple longitudinal cavities and it is a combination of peristaltic pump and helical progressive cavity pump. These longitudinal cavities are formed by flexible tubes (hoses) displaced circularly inside a steel pipe. A helical rotor rotates in the central space of this assembly compressing the hoses against the steel pipe. In function of the geometrical shape of the rotor, the fluid is pumped longitudinally inside the hoses. The problem of this pumping system is that between the hoses and the rotor and also between themselves results a useless empty spaces, which hinders the reduction of the pump dimensions. [0004] To try to solve the problems presented above, PI 0403685-9 proposes a pump with centered helical rotor, the persisting problem in this concept is that the stator is made of rubber. When used in petroleum drillings, the composition components of the petroleum end up attacking the rubber, aggregating or removing some component of its composition. Besides this inconvenience the helical progressive cavity pumps cannot work at elevated temperatures, since the rubber deteriorates. [0005] All existing pumping systems in the state of the technique work with low rotation because they work decentralized. OBJECTIVE OF THE INVENTION [0006] The objective of the present invention is to provide a progressive vortex pump, aiming at solving the problems encountered in the rubber component, vibrations and pump size. [0007] In order to achieve the above objective, the progressive vortex pump of the present invention has multiple stages, works at the center, eliminating totally system vibration, all components are metallic, which can work at very elevated temperatures. BRIEF DESCRIPTION OF THE DESIGNS [0008] The invention as well as its objects and advantages can be better understood with reference to the description of the preferred incorporations that follow together with the enclosed figures, where: [0009] FIG. 1 represents a front view of a PCP pump (11) installed in a well; [0010] FIG. 2 represents a front view of a progressive vortex pump (21) installed in a well; [0011] FIG. 3 represents a front view of a PCP pump (11) sectioned longitudinally, where we can observe all its internal components; [0012] FIG. 4 represents a front view of a vortex pump (21) sectioned longitudinally, where we can observe all its internal components; [0013] FIGS. 5, 6 and 7 represent front views of the progressive vortex pump (21); [0014] FIG. 8 represents a detail of FIG. 7 where we can observe the vortex (71) operation (the direction of fluid rotation within the stage can be observed); [0015] FIG. 9 represents a detail of FIG. 8 where we can observe the passage of the fluid from one stage to another (81); [0016] FIG. 10 represents a blown out view of the vortex pump (21) components; [0017] FIG. 11 represents a detail of FIG. 10 where we can observe the 3 basic components of the vortex pump (21) (diffuser (111), rotor (112), stator (113)). DESCRIPTION OF THE INVENTION [0018] All vortex pump (21) components are metallic, this way they can work at high temperatures without damaging any component of the vortex pump (21). The difference of the progressive vortex pump (21) in relation to those already existing in the market is the number of stages, because due to the geometry of the parts, diffuser (111), rotor (112) and stator (113), we can mount the number of stages that we may wish. [0019] The mounting of the progressive vortex pump starts with the shaft, where the rings (sliding, graphite, sealing), bearings, pump pipe, valve, diffuser (111), rotor (112) and stator (113) are assembled. For this reason the diffuser (111), rotor (112) and stator (113) assembly, forms a stage and can be mounted in accordance with the number of stages needed to reach a particular pressure for the application in which the pump will be used, where there is no limit to the number of stages.
