High-Pressure Gas Compressors - FLEXI-POWER

Hydro-Pac, Inc.

Variable capacity via automatic stroke rate adjustment
Hydraulically driven intensifier design
Efficient use of available horsepower
Patented free-piston design
Can be started under full load
Intensifier mounted over hydraulic power unit

The FLEXI-POWER High-Pressure Gas Compressors by Hydro-Pac are hydraulically driven compressors designed for high-pressure production applications requiring variable capacity and efficient use of available horsepower. These systems utilize a hydraulic intensifier combined with an adaptive stroke rate mechanism that increases compressor capacity at lower discharge pressures. Unlike fixed-capacity compressors, FLEXI-POWER units automatically adjust stroke rate based on operating conditions, reducing fill times and improving overall efficiency in dynamic applications such as gas storage and transfer. The compressors are available in single-stage and two-stage configurations and are suitable for a wide range of industrial gas compression applications.

Use Cases

Gas transfer and circulation
High-pressure chemical reactions
Material testing
Gas leak testing
Calibration of transducers and instruments

Capabilities

High-pressure gas compression using hydraulic intensifier system
Single-stage and two-stage configurations
Discharge pressure range: 70 to 415 MPa (10,000 to 60,000 psi)
Power range up to 150 kW (200 hp)
Variable capacity improves performance across pressure ranges
Typical two-stage inlet pressure range: ~35 to 200 bar (500–3000 psi)
Suitable for continuous and high-demand industrial applications

Hydro-Pac, Inc. For almost 40 years, Hydro-Pac has designed and manufactured a complete line of high-pressure liquid pumps and gas compressors. If you are looking for a pump or compressor to incorporate into your system; we can help. If you want a turn-key system with compressors, PLC based controls, valves and piping; we can help. If you need a one-of-a-kind pump, gas compressors or system; we can help with that too. We welcome the chance to work with you on your application.
