Gas booster pump

Working principle: the piston (plunger) with different end area in two independent chambers moves. Through the balance principle of force, small pressure is applied to large area piston in low pressure chamber, and large pressure can be output by small area piston (plunger) in high pressure chamber. The larger the area ratio, the higher the output pressure.

The supercharged gas is completely separated from the driving gas and is not mixed with each other. It is not only suitable for compressed air, nitrogen, helium, argon, carbon dioxide and other inert gases, but also suitable for the pressurization of combustible gases such as oxygen, hydrogen, methane and natural gas

No oil lubrication, high pressure gas piston ring and other pneumatic components do not need to add lubricating oil when they are working, which can save operating costs, prevent oil and gas pollution, and meet the requirements of environmental protection.

The maximum output pressure is 2690bar (269mpa).

When the set output pressure is reached, the big and small pistons reach the balance, and the booster pump stops working. At this time, there is no energy consumption and no heat generation. It has good pressure retention characteristics. When there is pressure leakage, the booster pump automatically replenishes the pressure, and frequent starting has no effect.

Small size, compact structure, easy to install, easy to automatic control, no lubrication, no need for full-time maintenance and durability.

Because it doesn't need electricity and has no spark, it is suitable for coal mine, petrochemical, chemical and other explosion-proof occasions.
