PDC Diaphragm Compressors for Industrial Systems

The triple diaphragm set ensures that the process gas is completely isolated from the hydraulic oil. PDC compressors do not use dynamic seals, eliminating potential seal particulate contamination. Filters and oil removal systems are not necessary – hydraulic oil cannot migrate into the process gas.

Our membrane metallic diaphragm compressors can achieve typical compression ratios up to 10:1 for certain models.

PDC compressors are capable of sub-atmospheric as well as high suction pressures. Our compressors are used in applications requiring low or high compression ratios, and in applications requiring intermittent or continuous service duty.

PDC compressors are completely instrumented for safe and automatic operation.

All aspects of PDC’s diaphragm compressors enhance component life, improve operability, and reduce and simplify maintenance. Our diaphragm cavity contours, which control stress in the diaphragms, provide uniform stress distribution. PDC also uses special manufacturing processing on the diaphragm surfaces to enhance fatigue life. PDC customers experience continuous running times of 10,000 to 40,000 hours between routine maintenance, minimizing the need for spare parts replacement.

PDC compressors typically only require routine oil changes.

PDC compressors are completely instrumented for safe and automatic operation.

PDC Diaphragm Compressors use non-flammable hydraulic fluid and all process-wetted components, which are constructed from corrosion-resistant materials for processing corrosive or oxidizing gases. This ensures safe operation and prolongs the life of maintenance components.

Our diaphragm compressors use static seals. There is no migration of gas into the crankcase – as such, the crankcase does not require purging or venting. PDC compressors’ gas system integrity also prevents leakage of gas into the atmosphere.

PDC compressors are automatically reprimed at start-up. Manual start-up requires an experienced compressor technician to reprime the diaphragm compressor. Incorrect priming can cavitate the compressor and damage the heads, bolts, diaphragms, O-rings, process and hydraulic system. PDC Compressors avoid this potential issue with our cutting-edge repriming tech.

Below 85 dBA at 1 meter without sound-proofing enclosure.

PDC diaphragm compressors hydraulic systems are designed in such a way as to ensure uniform diaphragm deflection, prevent knocks, vibration, cavitation and yield smooth, and quiet compressor operation.

PDC compressors use a heavy flywheel to provide energy. In addition, Duplex and two-stage diaphragm compressors can be horizontally opposed to further reduce horsepower requirements and energy usage, resulting in ease of use and cost savings for the end user.

The oil regulating valve limits maximum hydraulic and gas pressure and ensures that the diaphragms completely “sweep” the upper and lower cavity contours to maximize displacement.

PDC Compressors provide a plunger-type injection system on all motor-driven diaphragm units. The injectors are also crank driven and precisely meter hydraulic fluid flow during the operation of the compressor.

The deflection and resultant stresses in PDC metal diaphragms are controlled by carefully designed cavity contours. We use state-of-the-art design and analysis tools as well as cutting-edge programs to model these.

At PDC Machines, we machine-process heads from a variety of materials for process gas compatibility. Our gold-standard process heads are constructed from 300 series stainless steel.

The diaphragm set consists of three plates. The upper or process side, the lower or hydraulic side and the middle diaphragm. The middle diaphragm is brass to preclude galling. The upper and lower are typically 301 series stainless steel for most applications. However, the upper diaphragm material can be supplied in alternate materials, such as Inconel 718, for process compatibility.

We offer an extensive variety of static elastomeric O-ring seals for process gas compatibility. Options include Buna-N, Viton, and Teflon-encapsulated Viton and Kalrez.

Included with every PDC diaphragm compressor is a leak detection system. This system detects diaphragm or seal failures. Our leak detection system monitors the gas and hydraulic sides of the compressor and will sound an alarm and/or shut down the compressor when it detects an anomaly or failure. Proper maintenance, operation, and clean/dry process gas prolongs component operating life.

Compressor process check valve design depends on operating conditions and the process gas itself. PDC compressors typically utilize cartridge- or plate-style check valves. PDC designs valves and valve pockets for easy removal and maintenance.

PDC compressors are automatically reprimed at start-up and unloaded upon shutdown. This process is an important procedure that not only provides for maximum efficiency but also eliminates the need for an operator to start up or reprime the compressor.

Our hydraulic systems are designed to ensure uniform diaphragm deflection, prevent knocks, vibration, and cavitation, and yield smooth, quiet compressor operation. We employ unique oil distribution techniques to eliminate pressure differentials and gradients. The system utilizes an automatic priming pump, positive displacement high-pressure injection pump, and oil relief valve with bypass valve for smooth, easy starting.

PDC’s diaphragm compressors can be designed and certified to comply with Canadian, European, South Korean, Japanese, United States, Korean, Chinese, and other international codes and standards.

PDC has an ISO 9001:2015 certified quality management system.

All diaphragm compressors are mechanically run and performance is tested for eight hours.
