GD2 Membrane Compressor

GD2 Membrane Compressor focused on relatively low gas flow and high-pressure compression duties. The supplied models cover gas capacities from 10 to 72 Nm³/h, with suction pressures ranging from atmospheric pressure to 1.2 MPa and exhaust pressures up to 15.7 MPa. Different models combine flow, suction pressure, exhaust pressure and motor power in different ways, allowing the compressor to be matched to the actual process rather than selected by capacity alone. The specified media include high-purity gases, inert gases, flammable and explosive gases, toxic gases and other special gases.

GD2 Capacity and Discharge Pressure Range

The GD2 Series is suited to gas compression duties that combine moderate flow requirements with substantial pressure increases.

According to the listed specifications, capacity ranges from 10 to 72 Nm³/h, while selected configurations achieve discharge pressures of 14.7–15.7 MPa.

This operating profile makes the GD2 Series worth considering for applications that require high-pressure gas delivery without large volumetric throughput. The appropriate model depends on the required flow rate, inlet pressure, target discharge pressure and gas properties.

Industries Where GD2 Can Be Applied

Industrial Gas Systems

GD2 Membrane Compressor can be considered for dedicated gas compression and pressure-boosting duties where the required capacity falls within its 10–72 Nm³/h range.

Petrochemical and Chemical Processes

Special gases and process gases may require controlled compression before entering another process stage. Model selection should be based on the actual gas composition and pressure conditions.

Electronics and High-Purity Gas Applications

Where gas purity is an important process requirement, membrane compression provides a configuration in which the process gas is separated from the compressor's hydraulic and lubrication side.

Research and Laboratory Gas Systems

The relatively focused capacity range can suit certain research, testing and specialized gas supply systems where gas demand is lower but a substantial pressure increase is required.

Special Gas Applications

For flammable, explosive, toxic or otherwise special gases, the compressor configuration needs to be reviewed according to gas properties, operating pressure, temperature, sealing requirements and applicable safety requirements.

FAQ

What is the flow range of GD2 Membrane Compressor ?

The supplied GD2 models cover nominal flow rates from 10 to 72 Nm³/h.

Which GD2 models reach around 15 MPa?

Several configurations are in this pressure range. GD2-20/12–160, GD2-25/6–160, GD2-25/5–160 and GD2-25/4–160 are listed at 15.7 MPa exhaust pressure, while GD2-10/150, GD2-20/5–150, GD2-25/1.5–150, GD2-35/12–150 and GD2-40/5–150 are listed at 14.7 MPa.

Can GD2 compress gas from atmospheric pressure?

Yes. The supplied GD2-20/12, GD2-10/160 and GD2-10/150 configurations specify atmospheric suction pressure.

How does suction pressure affect model selection?

Suction pressure changes the pressure increase required from the compressor. It should therefore be considered together with gas flow and required exhaust pressure when selecting a GD2 model.

Which gases can GD2 handle?

The supplied specification lists high-purity gases, inert gases, flammable and explosive gases, toxic gases and other special gases. Final compatibility and configuration depend on the actual gas properties and operating conditions.

What motor powers are available?

The supplied GD2 models include 7.5 kW, 15 kW and 18.5 kW motor configurations.

Can Jinding provide a custom configuration?

Jinding can review the gas medium, flow rate, suction pressure, exhaust pressure and other operating conditions to recommend a suitable configuration. Non-standard requirements can be discussed during technical selection.
