The invention relates to oil and gas industry, particularly to structural elements of sucker rod pumping units (SHGNU) and can be used advantageously in the oil and gas industry. Sh comprises a tubular body and a head, mounted on the ends of the tubular body, and, in accordance with the proposal, each head is solid and hermetically secured to the corresponding end of the tubular body. The proposed utility model tasked with reducing the weight of influence on the flow rate and Sh efficiency during operation SHGNU on the well. The problem is solved by creating the conditions for the use of buoyancy liquid, which filled the well.
