Proposed method of topping-up and pumping of nondried gas by means of positive-displacement reciprocating-action device includes delivery of nondried gas into compression chamber. According to proposed method, hydraulic seal is formed in compression chamber by filling the chamber with liquid in volume not less than volume taken by charger. During each cycle of charger operation, volume of hydraulic seal is maintained by delivering liquid from outer source in amount ΔV hs  ≥ V g +V l  where ΔV hs  is hydraulic seal replenishment volume: V g  is expected part of hydraulic seal volume filled with free gas; V l  is maximum expected volume of leaks and carry over of liquid from hydraulic seal during each cycle. Volume of compression chamber is not less than two columns taken by charge plus volume of replenishment of hydraulic seal. Mixture of nondried gas compressed to required pressure and let out of compression chamber and part of liquid from hydraulic seal are directed into gas-liquid separator from which separated liquid is directed into discharge device, and gas, to consumer. Mixture is let out of compression chamber through discharge valve whose passage area is chosen to provide passing of liquid without water hammer.
