The gas pump unit powered by natural gas (gas pump) is composed of a drive cylinder with a piston or in the “D” version of the pump pistons. Lubrication of the drive part (piston, piston rings and connecting rod seals) is lubricated with oil in a dispersed state, which is delivered by the drive natural gas via the gas distributor and from the lubricator. The gas inlet should be under pressure up to 14 bar, and the exhaust into the counterpressure pipe up to 2.5 bar. The exhaust gas is not released into the atmosphere, but is sucked in by a compressor and sent for further processing.
This unit is intended for the exploitation of oil and gas for dosing additives both in the pipe for the transport of crude oil and in the process of primary gas processing.
Its advantage is that it is not powered by an electric motor, and therefore is not the cause of a possible fire.
