Their main special feature is the compact, totally sealed bellow between the body and the cap made of PTFE (Teflon). This protection safely encapsulates the ACE rolling diaphragm from the outside environment. Aggressive fluids don't stand a chance. The PMC series is an excellent alternative if the accessory option of the SP type air bleed collar cannot be used due to a lack of compressed air. Self-compensating shock absorbers react to changing energy conditions, without adjustment.
The PMC series self-compensating miniature shock absorbers, produced from stainless steel, are primarily suitable for use in the food industry, but are also wherever a high-quality appearance is important e.g. in shipbuilding.
