Product Description

Product Description

Diaphragm compressor according to the needs of the user, choose the right type of compressor to meet the needs of the user. The diaphragm of the metal diaphragm compressor completely separates the gas from the hydraulic oil system to ensure the purity of the gas and no pollution to the gas. At the same time, advanced manufacturing technology and accurate membrane cavity design technology are adopted to ensure the service life of the diaphragm compressor diaphragm. No pollution: the metal diaphragm group completely separates the process gas from the hydraulic oil and lubricating oil parts to ensure the gas purity.

Key Components of a Compressor
1.Compressor Main Unit
The main unit types of compressors include: diaphragm type, piston type, screw type, and liquid-driven type. The main unit comprises the following components: crankcase, crankshaft, connecting rod, piston, cylinder block, cylinder head, and sealing elements.
2.Piping and Cooling System
Common cooling methods for compressors include water cooling or air cooling. Some piston compressors utilize a hybrid approach with gas air-cooling and partial water cooling for the cylinder head. Cooling systems can be custom-designed and manufactured according to customer requirements.
3.Power Drive
Compressors are predominantly driven by electric motors (over 90% of applications). In scenarios without electrical power, diesel engines or natural gas engines may be employed. Our company offers custom-engineered engine-driven solutions based on customer specifications and machine models.
4.Electrical Control System
The electrical control system is divided into high-voltage and low-voltage sections:
High-voltage section: Refers to power supply systems with voltages of 220V/380V or higher, primarily used for driving high-power equipment such as motors.
Low-voltage section: Includes controllers, instrumentation, and other low-voltage devices, typically operating at safe voltages of 24V or 36V.
5.Oil Pressure System
The lubrication system is critical for stable compressor operation. It not only lubricates moving components and reduces operating temperatures but also ensures discharge pressure stability in diaphragm compressors, where oil pressure directly governs consistent performance.

Application 
Food industry, petroleum industry, chemical industry, electronics industry, nuclear power plant, aerospace, medicine, scientific research.

Outlet pressure at 50bar 200 bar, 350 bar (5000 psi), 450 bar, 500 bar, 700 bar (10,000 psi), 900 bar (13,000 psi) and other pressure can be customized . 
Brief Description

Our hydrogen compressors are engineered for safe, efficient, and oil-free compression of hydrogen gas. Designed to handle hydrogen's unique properties (low density, high diffusibility), they ensure zero leakage, maximum purity, and long-term reliability for high-pressure applications.

Key Features

• Oil-Free & High Purity: 100% dry-running design prevents oil contamination; maintains hydrogen purity ≥99.99%.
• High Pressure Capability: Discharge pressure from 0.5 MPa up to 90 MPa (ideal for refueling stations, storage, and industrial processes).
• Superior Sealing: Primary & auxiliary packing; leakage rate <0.005% (ISO 15848-1 Class 3).
• Anti-Hydrogen Embrittlement: Key parts (316L stainless steel) pass NACE TM0177 tests.
• Safety Certified: Ex d IIC T4 explosion-proof, compliant with ATEX, CE, GB 3836 standards.
• Compact & Modular: Space-saving, easy integration, installation & maintenance.
• Cooling: Air or water cooling options.
