Providing World-Class Diaphragm Compressors

Utilising a powerful combination of engineering and manufacturing excellence and a dedication to working with our customers, Pdc provides engineered solutions to satisfy difficult gas compression needs.

The leak-tight and contamination-free features of Pdc's diaphragm compressors provide numerous benefits.  When toxic or hazardous gases are being processed, these compressors protect the health of workers and the environment, and maintain a safe operating area.  Since the process gases are totally isolated and have no contact with hydraulic, lubricating, or cooling fluids, high-purity and expensive gases can be processed without any contamination or losses.

Some of the other features and benefits of Pdc's diaphragm compressors include: 

  Design pressures to over 4,100 bar/60,000 psig

    Gas flow rates over 1,500 Sm3/hour/880 Scfm.

Horizontally opposed designs available for high-efficiency operation.

   Electric and air-driven models

   Process contacting metals are available in a variety of alloys for compatibility with process gases.

   Proccess contacting seals are available in a variety of elastomers and ductile metals are compatibility with process gases.

   Unique cavity design feature for low or high-pressure operations.

Experience Reliability & Service

Pdc is committed to continous product improvement and the development of innovative designs and manufacturing processes to maximise compressor performance and value.

Drawing on our decades of experience and the use of our proprietary software for sizing, stress analysis and detailed engineering drawings, Pdc provides high reliability and low maintenance diaphragm compressors.  These compressors demonstrate superior diaphragm life as a result of our cavity contour design, our exclusive diaphragm manufacturing process, and critical quality control.  All models include automatic positive priming and injection pumps to reduce knocks, cavitation, and vibration for smooth start-up and operation.  Critical components are manufactured and verified to exacting tolerances utilizing computer numberical controlled(CNC) machining and coordinate measurement(CMM) quality control.

After assembly, every compressor is subjected to rigourous in-house testing and is made available for customer inspection.  Each unit alsow includes an  O & M manual with drawings and component details.  Pdc stocks critical spare parts for quick shipment and offers responsive technical and field support when the need arises.
