SUPER Series B Gas Booster Pumps are two-stage booster pumps that compress gas through two stages to achieve high pressure. The driving air pressure for the gas booster pump ranges from 0.2 MPa to 0.8 MPa, and the inlet gas pressure ranges from 0.5 bar to 10 bar, with a maximum output pressure of 90 MPa.
Equipped with air-controlled reversing valves, the booster pumps require no power supply and feature automatic reversing function. The entire pump body is constructed of aluminum alloy and stainless steel. This product can boost various gases including air, nitrogen, hydrogen and more.
For the air-driven section of this series, lubricated drive gas is required to lubricate seals and other internal components. The driving piston diameter of this pump series is 160 mm.
The working principle diagram of Simint gas booster pumps is shown below.

Working Principle of Gas Booster Pump

SUPER gas booster pumps adopt compressed air cylinders as power to pressurize target gas. This pump is a two-stage unit that boosts the target gas via primary and secondary compression.
The driving cylinder features a larger bore than the gas compression cylinder. Based on the area ratio between the two cylinders, the pressure of the target gas is increased. The operating principle of the booster pump follows Pascal's Law: a large-area piston pushes a small-area piston to generate pressure amplification, which ultimately raises the pressure of the target gas.
The SUPER gas booster pump is equipped with a pneumatic reversing valve for automatic reciprocating switching.
