摘要

Self-sealing electrobomba with prefilter for the impulsion of liquids. At the inlet (13) of the diffuser (14) of the hydraulic part of the electro-pump, this station is included with a stainless steel cap (15), adapted to serve closure bearing with the roller and to facilitate the friction between both bodies. For the hermetic closure of the external vessel (10) of the prefilter (2), a torque joint (16) is provided on the bottom of the lower skirt (17) of the cover (18), to avoid that the filtration removed in the filter can insert between the fillet (19) of the cap closure thread (18).
