Abstract
Gear pump, in which the gears or toothed wheels have projecting shafts on both sides and mounted on bearing plates, placed exactly one on each side and in the bore of the pump case and applied against the lateral faces of the sprockets, with a narrow gap between each bearing plate and the corresponding cover of the pump housing, in order to maintain a play that is as constant as possible and also in which the portions of the gap that communicate with the discharge channel of the pump are limited and closed by a ring-shaped gasket lining, characterized by the fact that a system formed by four gasket-shaped gaskets is provided on the external face of each bearing plate. symmetrical and/or symmetrically coordinated rings the same in relation to the gear plane of the sprockets as in relation to the median plane passing through the axles of 2 wheels and perpendicular to the previous plane and made up of a central joint that surrounds the bearing bores of the two sprocket axles with the greatest possible separation, two intermediate joints symmetrically arranged on one and the peripheral joint, on the other, face each other. as possible and are preferably in direct contact.
