GD2 Diaphragm Compressor

Jinding GD2 Diaphragm Compressor is designed for gas compression applications where gas properties, purity requirements, discharge pressure and flow rate all influence equipment selection. For specialty and industrial gases, factors such as leakage control, flammability, toxicity and material compatibility must be considered when determining the appropriate compressor configuration.

The GD2 Series uses a flexible metal diaphragm to separate the process gas from the hydraulic drive system. As the diaphragm moves, the compression chamber volume changes, drawing in and compressing the gas before discharge. This design prevents direct contact between the process gas and lubricating oil, making the compressor suitable for applications that require gas purity control and effective containment.

Technical Specifications

Core Advantages

1.Oil-Free Gas Compression:

The most important feature of a diaphragm compressor is the separation between the process gas and the lubricating system. In the GD2 Diaphragm Compressor, the diaphragm isolates the gas compression chamber from the hydraulic drive section, so the process gas does not directly contact lubricating oil during compression.

2.High-Pressure Capability:

The GD2 is designed for applications requiring pressure boosting and high-pressure gas compression. Depending on the selected model and application, representative configurations can reach discharge pressures of up to 15.7 MPa.

3.Reliable Gas Sealing:

Gas leakage is an important consideration when handling toxic, flammable, explosive or valuable gases. The diaphragm creates a sealed separation between the process gas and the drive system, providing a compression structure suitable for applications where gas containment and leakage control are important.

4.Suitable for Multiple Specialty Gas Types:

Our Diaphragm Compressor can be configured for a wide range of industrial and specialty gases. Material selection and compressor configuration can be evaluated according to gas properties, including purity, toxicity, flammability, explosiveness and chemical compatibility.

5.Flexible Pressure and Flow Matching:

Different industrial projects require different combinations of pressure and capacity. The GD2 includes configurations ranging from approximately 10 to 72 Nm³/h, allowing Jinding to match the compressor more closely to the actual gas compression duty instead of using an unnecessarily oversized system.

Who Is the Product Designed For?

The GD2 Diaphragm Compressor is designed for industrial gas applications that require controlled compression, reliable gas containment and separation between the process gas and the hydraulic drive system.

Typical applications include industrial gas production and distribution, gas filling and cylinder charging, specialty gas handling, and chemical or petrochemical processes where gas purity and sealing performance are important.

It is also suitable for research facilities, laboratories and equipment integrators that require gas compression within defined pressure, flow and operating parameters.

For applications involving flammable, explosive or toxic gases, the gas composition, required discharge pressure, flow rate and operating conditions should be provided during technical consultation. These details help Jinding evaluate the appropriate materials, sealing arrangements and compressor configuration.

Quality Assurance and Manufacturing Control

Established in 1995, Jinding Technology specializes in industrial compressors and gas equipment. Its manufacturing base in Dandong, China, integrates machining, welding, assembly, testing and technical support.

The facility is equipped with more than 100 sets of machining and testing equipment, supporting component manufacturing, precision processing and compressor assembly.

For diaphragm compressor projects, engineering evaluation considers the gas medium, pressure requirements, flow rate and operating conditions to determine a suitable equipment configuration before production.

Jinding's management systems cover quality, environmental protection, occupational health and safety, and information security. The company holds ISO 9001, ISO 14001, ISO 45001 and ISO 27001 certifications, as well as CE certification.

For diaphragm compressors, equipment reliability depends on more than final inspection. Material compatibility, machining accuracy, diaphragm assembly, sealing performance and appropriate testing are all important considerations in manufacturing equipment for specific gas compression duties.

FAQ

1. What gases can the GD2 Diaphragm Compressor compress?

It can be configured for high-purity gases, inert gases, flammable and explosive gases, toxic gases and other specialty gases. The final configuration should be determined according to the actual gas composition and operating requirements.

2. What is the maximum discharge pressure?

Representative GD2 models can provide discharge pressures of up to 15.7 MPa. The available discharge pressure depends on the selected model, inlet pressure, gas medium and required flow rate.

3. What flow rate range is available?

The listed GD2 models provide nominal volumetric flow rates ranging from 10 to 72 Nm³/h. If your project requires a different flow rate, Jinding can evaluate the operating conditions and recommend a suitable compressor configuration.

4. Does the compressed gas contact lubricating oil?

No direct contact occurs between the process gas and lubricating oil in the compression chamber. The diaphragm separates the process gas from the hydraulic drive and lubrication system.

5. Can the product be used for cylinder filling?

Yes. Depending on the gas medium and required filling pressure, the GD2 can be used for gas pressure boosting, transfer and cylinder filling applications. The required inlet pressure, outlet pressure and flow rate should be provided for technical selection.

6. What information is required to select a Diaphragm Compressor?

For an accurate recommendation, please provide the compressed gas, gas composition or purity, inlet pressure, required outlet pressure and required flow rate. Information about operating hours, cooling conditions, installation environment and electrical requirements can also help determine the appropriate compressor configuration.
