Another improvement consists in providing pump of the driving solenoid set 10 cooling device, that comprises inverting the me chanism position, so that mentioned solenoid 10 is located in the upper regi on of the pump and housed within the inverted tubular cup 40; and the transmission member 20, subject to the solenoid; and the pumping set 30, subject to the transmission member 20; and the water intakes 38, are dispo sed in the lower region of the pump; said inverted tubular cup 40 defines an annular pass 41 in connection with the frame wall 1, whose upper end com municates with the upper pumping outlet 2 of the frame 1 and the lower end of said pass 41 communicates with the pumping outlets 33 communicant with the auxiliary pumping chamber 32 of the pumping set 30; said pass 41; the circulating water in the same; the cup wall 40, that encloses the driving solenoid 10 constitute mediums of heat exchange, that provides the driving solenoid 10 cooling, in order to be possible to incorporate the improvement hereinbelow mentioned, the pump's construction has been completely reformulated, as more in details hereinafter described. Thus, the frame set 1 is composed, essentially, of : an external cylindrical frame 1 with external diameter selected to be received inside the tubular well and provided with conical upper end, that ends in the pumping outlet 2 and lower end that has assembled a nozzle 4 of the pump accessories fitting. In the inner part of the external cylindrical frame 1 and by keeping an space in connection with the same, which constitutes the pass 41, it is foreseen the inverted cup 40, that houses the solenoid 10, which is cylin drical and escalated and foresees a narrower upper section, in which it is as sembled the end of the solenoid core 10 and wider lower section, extended by the major part of the cup height, in which it is housed section of the core and the coil winded in the same, that constitute the solenoid 10; below these it is disposed the base 21 of the transmission member 20 subject to the solenoid and under mentioned base 21 and around the transmission member 21 it is foresee the pumping set 30, which besides its pumping function provides the insulation amongst the wet and dry parts of the pump. The pumping set 30 it is housed into a set of cylindri cal wall 40' assembled in continuation to the cup 40 upper end, which defi nes a pair of upper backstops, between which are fastened a peripheral tur ned edge of the upper base of the cover 31 and the seal ring of a seal set 39, that still foresees an upper 0-ring, inserted between the base of the cover 31 and the set of wall 40'; in the intermediate region of said set of wall 40' are foreseen the pumping outlets 33 radially placed and in the upper end, menti oned set of wall 40' has assembled a first closing under substantial shape of cup 40", whose upper end foresees an assembly flange slightly conical with concave upper end, which defines the seat 35, in which the cupping 34 ope rates and in continuation to such flange it is foreseen a cylindrical section, that defines the admission chamber 36, in whose bottom are foreseen the water intakes 38 and is assembled the vane valve 37, that controls the latter; under mentioned first closing in shape of external cup 40" it is foreseen a second closing in the shape of external cup 40'" provided with turned edge of upper assembly placed under the flange of the first closing 40" and whose bottom is projected outside the nozzle 4 of the accessories fitting, supports the first closing 40" and foresees holes of water intake 38', lined up with holes 38 of the admission chamber 36; the mentioned first 40" and second 40'" closings are assembled so as they can be disassembled by means of de vice that includes radial tightening devices 5. The core 11 of the solenoid 10 is cylindrical and fore sees a lower diametrical crack, which defines double-split section extended for almost all core height and where the coil 12 is winded with enameled vvi re; the core base, of laying in the upper narrow section of the cup 40, does not foresee the crack and is proyided with through axial hole, in which it is located the coil's electric feeding cable 13, which is extended outside of the bottom of .cup 4.0 and .of the .upper conipal wall of the external frame 1 , so as not be located beyond the projection of the external frame 1 perimeter and thus making easy the pump installation in .tubular well. The base 21 of the ansmission member 20, that is subject to i ^ solenoid 1.0, is also cylindrical and composed of an aggregate of material subject to magnetic attraction and is fastened to the member 20 by means of pins, welding and aluminum. The pump, constructed as hereinbefore described, has three diverse ways of use. In one of the possibilities, (Figure 1) the pump is used without the auxiliary .accessories, assembled in the middle .of the tubular well and the water collection is directly made by the inlet openings 38, 38'. in other possibility, the pump receives in its nozzle 4 .of .accessories fitting .a base 5.0 (Figures 3 and 4) to be used supported in the base as a suction pump. The base 50 is a tubular body comprised by a cou pling -cylindrical upper section 51 in the nozzle 4 of the pump .and by a coni cal-tubular trunk lower section 52, which is extended and widened as from that, of support in the bottom of the well .and provided with a water intakes 53 lining up, placed close to the upper end of the mentioned conical-tubular trunk section 52. In another possibility' of use, the pump receives a coupling 60 nozzle 4 (Figures 4 and 5), purposed to connect the pump inlet to the outlet of a second pump, in order to assemble various pumps in series vertically placed, for reaching biggest depths or horizontally placed for pres surization of the pumping lines. The coupling 60 is a tubular body comprised by a coupling cylindrical end 61 in the pump nozzle 4, intermediate conical section 62 and cylindrical extreme section of lower diameter 63 of receiving and fastening of the connection nipple (64) to a pump outlet. In this way of use, at least the pumps following to the last upstream pump, receive external belts made of rubber-type material 70, purposed to fasten the main electrical feeding cable 13', from which are derived the cables 13 that reach the pumps. In this way, the pump, object of the present pioneer patent, can be properly applied in tubular well, by taking into account that has dimensioning proper to such purpose, without however have its efficien cy reduced. The cooling device of the present pump, as hereinbefore conceived and described, solves in proper way the solenoid- heating problem, by improving both the pump output and useful life. And, yet, the possibility of connecting the pump to different accessories will make possible a wide flexibility' of its use, by more completely fulfilling the requirements of the consumer market. Within the basic conception hereinbefore described, it is being pled the possibility of presenting the pump, object of this pioneer patent, changes relating to materials, dimensions and constmctive details without leaving the sphere of the requested protection. For this purpose, the pump might have its frame made of stainless steel or aluminum (Figures 1 to 5) or of engineering plastic (Figure 6), solutions which are substantially preserving the same characteristics, yet incorporating only some constmctive differences, however related to the possibilities of arrangements resulting from the materials utilized in its construction. Thus, the pump with plastic frame has substantially the same construction of that one made of steel or aluminum, except that foresees a second lower closing 40'", which corresponds to the second closing 40" of the other version, comprised by a cup that is coupled to nozzle 4, whose bottom has grate shape and supports the valve 37' admission chamber 36' and is able to receive accessory for connection to the second pump inlet. The pump, object of the present pioneer patent, is to be used in the field of the hydraulic installations, particularly those purposed to water pumping, preferably water pumping from tubular well and is yet used for pressurization of pumping lines.
