FIELD: gas and oil producing industry.
SUBSTANCE: pump is designed for transfer of gases and gas-liquid mixtures. Proposed pump has hydraulic unit each space of which consists of displacement part with displacer and suction valve for liquid. Compression part contain delivery valve and gas intake valve placed under delivery valve. Dividing unit with piston is installed between displacement and compression parts. Said unit is made in form of nonreturn valve whose seat is located between displacement and compression parts of working space. Valve plate is suspended from piston reciprocating in compression part in time with displacement of displacer in displacement part of working space. Valve plate is suspended from piston for adjusting length of suspension, and seat mounting place can be adjusted in height of location.
EFFECT: provision of topping up of gas or gas-liquid mixture at minimum consumption of liquid without additional booster feed pump.
