METAL DIAPHRAGM COMPRESSORS FOR ULTRA-CLEAN AND SAFE COMPRESSION

sera metal diaphragm compressors compress sensitive and valuable gases absolutely contamination-free.
Metal diaphragm compressors are the best choice for applications in microelectronics, semiconductor technology and dosing technology.
Due to the almost complete absence of leakage to the outside, gases that are highly critical for humans and the environment can be compressed without hesitation. sera metal diaphragm compressors are therefore often used in applications with toxic gases.
Depending on the requirements and type of medium, different material qualities are used for the components in contact with the gas. In this way, high corrosion resistance and long service lives of the parts in contact with the gas can be achieved.

Structure and function

A metal sandwich diaphragm clamped with static seals is located between the valve head and the upper part of the piston housing. It hermetically separates the gas chamber from the oil-lubricated actuator. This completely prevents contamination of the medium by lubricants and particles. Thanks to this design, sera metal diaphragm compressors are also hermetically sealed from the outside, so that toxic and explosive gases can be compressed without any problems.
The gas chamber is cyclically enlarged and reduced by the oscillating movement of the clamped diaphragm. The gas drawn in via the suction valve is compressed in this way and pushed out via the discharge valve. The oscillation of the diaphragm is triggered by an oil cushion, which is cyclically pressurised by a piston driven by a crank mechanism.
sera metal diaphragm compressors comply with the requirements of the Machinery Directive, the ATEX Directive and the Pressure Equipment Directive of the European Union as standard.
