FIELD: engines and pumps, mining.
SUBSTANCE: invention relates to submersible devices for feeding reagent into well equipped with sucker rod pump. Device comprises reagent tank installed in well below oil producing equipment and reciprocating metering pump, which has its own drive, cavity of which is able to be connected with suction channel with reagent reservoir, and discharge cavity – with well. Drive of metering pump is in form of piston hydraulic cylinder of one-way action, cylinder of which is made in casing mounted on tubing string. Piston cavity of cylinder is hydraulically connected by channel to reagent vessel and to suction channel of dispenser pump, and piston is mechanically connected to casing by means of armature.
EFFECT: design is simplified, increase in ease of use.
