Optimum corrosion protection

Self-Compensating, Rolling Diaphragm Technology, TPU Bellow
Energy capacity 20 in-lbs/cycle
Stroke 0.5 inch

Hermetically sealed and rustproof: The Protection product family PMCN is also available in a stainless steel design. This is of particular interest to the food and packaging industries.

Their main feature is the compact, totally sealed bellow between the body and the cap made of TPU (thermoplastic polyurethane). This protection safely encapsulates the ACE rolling diaphragm from the outside environment. Aggressive fluids don't stand a chance.

The PMCN range 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.

The PMCN range 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.
