product introduction

The OMA Series Gas Booster Pumps are air-driven pneumatic booster pumps designed to compress and boost a wide range of gases such as air, nitrogen, oxygen, helium, hydrogen, and other industrial gases.
These gas booster pumps are commonly used as core components in gas boosting systems, pressure testing equipment, hydrostatic test / leak test auxiliary gas supply, and other high-pressure gas applications where stable, adjustable output pressure is required.

The OMA series includes single-acting / single-stage configurations and can be integrated into multi-stage systems when higher boosting requirements are needed. For users requiring special media compatibility, non-aluminum configurations can be selected for broader gas suitability.

Product Description

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.

Features and Functions

  • Air-driven operation: uses compressed air as driving source (PL), enabling safe operation without electrical power.
  • Stable and adjustable pressure boosting: output pressure is controlled by adjusting the driving air pressure.
  • Multiple pressure ratios available: from 2.5:1 to 100:1, allowing flexible matching to different gas inlet pressures and target outlet pressures.
  • Wide inlet pressure capability (by model): supports different gas inlet pressure ranges (PA) for industrial applications.
  • Defined output pressure logic: PB is directly related to PL, supporting consistent system pressure calculations.
  • Standard sealing options: seals configured as PTFE / FKM / NBR, supporting common industrial gas sealing needs.
  • Material options: Aluminum alloy / stainless steel versions available to adapt to different gas compatibility requirements.
  • Compact structure: standardized body dimensions across most models, supporting system integration and skid mounting

 

Product Advantages

  • Clear model selection logic: pressure ratio-based selection makes it easy to design a gas boosting system around a required outlet pressure.
  • High-pressure output capability: max outlet pressure listed up to 800 bar (model-dependent).
  • Stable pressure maintaining: pneumatic booster technology supports stable boosting behavior and controllable pressurization.
  • Broad gas suitability: designed for multiple industrial gases (air, nitrogen, oxygen, helium, hydrogen, etc.).
  • System integration friendly: consistent port sizes and compact dimensions simplify piping layout and installation in test benches or booster skids.

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.
