It is applied to sealing of the mouth of the oil wells equipped with sucker rod pumps, and also for carrying out production operations, research and maintenance functions. Unlike analogs has smaller mass-dimensional characteristics, a big set of technological capabilities at the minimum quantity of the locking and regulating elements.
The armature is completed with the D5-140 metering device which allows to make portsionalny supply of chemical reagents in a hole clearance of a well without its stop.
Device capacity — 5 liters.
