Diaphragm Compressors for cylinder filling, hydrogen fuel cell technology, or transfer of high purity or dangerous gases under pressure -- without contamination or leakage. This line of compressors, available through Haskel International, includes single and multi-stage diaphragm compressor models with displacements to 400 cfm (680 m3/hr) and pressures to 30,000 psi (2000 bar). A variety of head closure designs, power-frames, accessories, and materials of construction allow us to match a diaphragm compressor to most process parameters and your specific requirements

Benefits of Diaphragm Compressors

• Leak-tight compression: Self energizing static "O" ring seals in the head assembly prevent process gas leakage, a design feature pioneered by PPI. Depending on the process parameters, "O" rings of Buna N, Kalrez™, Aflas™, or composite elastomeric materials are used to achieve long life.
• Corrosion resistance: Process heads are machined from 300-series stainless steels, and diaphragm groups are 301ss for most applications. Other materials are available as required by the process gas.
• Increased diaphragm life: Critical quality control of all displacement cavities ensures proper contours, reducing combined stresses in critical areas, providing diaphragm compressors with extended service life.
• Low closure torque: The "O" ring sealed, flanged head assembly provides a positive seal while reducing bolt torque and maintenance downtime.
• Highly sensitive leak detection: PPI's leak detection system rapidly detects leakage from a diaphragm or diaphragm seal failure. All effluent leakage is totally retained in the head assembly, preventing environmental or process contamination and the associated expense of clean-up operations.
