Abstract
A liquid metering pump, characterized in that the pump body comprises a lower priming body that surrounds the seat of the suction valve, of the hemispherical type with integral stem, whose conduit communicates with the cavity attached to the membrane, communicated this, in turn, by means of a double duct, with the cavity of the impulsion valve, likewise of the hemispherical type with guide rod, carrying the upper hat of said valve integral a purge valve for the eventual elimination of the air introduced inside the pump body.
