OMA gas booster pumps operate using pneumatic booster technology, where the driving medium is compressed air (PL). The system converts low-pressure driving air into a higher gas output pressure (PB) through a defined pressure ratio.
The test/boosting pressure is adjustable and can be controlled by regulating the driving air pressure. The maximum driving pressure is 10 bar, and for long service life, the recommended driving pressure is ≤ 8 bar. The driving piston diameter of this series is 160 mm, and the pump is a single-acting structure.
OMA gas booster pumps are available in multiple ratios (2.5:1 up to 100:1), allowing users to select the most suitable model according to required inlet pressure and target outlet pressure.

Working Principle of OMA Gas Booster Pumps
OMA gas booster pumps convert compressed air energy into higher gas pressure output through reciprocating motion inside the pump body:
- Driving side (PL): compressed air drives the piston movement.
- Gas side (PA → PB): inlet gas is boosted to higher pressure according to the selected pressure ratio.
- The output pressure relationship follows: PB = Ratio × PL, and the system stops boosting when it reaches the pump stop pressure condition.
This principle supports stable boosting and predictable output pressure design, which is especially useful for pressure testing systems, leak test systems, and high-pressure gas filling / boosting stations.
