FIELD: petroleum industry.

SUBSTANCE: invention relates to petroleum production equipment, namely, to apparatuses for batching a reagent in order to protect the pumping unit from salt, paraffin deposition and corrosion. The apparatus comprises a container with a liquid reagent, equipped with an inlet in the upper part and an outlet in the bottom, a mixing chamber with a batching apparatus, a reducer gearbox, and a hydraulic turbine. The batching apparatus is made in the form of a disk with a hole, mounted on the driven shaft of the reducer gearbox and pressed to the bottom of the container by a spring. When the disk rotates, the hole in the bottom of the container aligns with the hole in the disk, and the hydraulic line between the container and the mixing chamber opens.
