Diaphragm bellows

HYDRA® diaphragm bellows consist of diaphragm rings welded together in pairs. They have a high specific expansion compensation (up to 80% of the length) and a very small spring rate. Diaphragm bellows are ideal for use in low pressure and/or vacuum applications.
HYDRA® diaphragm bellows are employed in vacuum technology, the aerospace industry, medical technology, special valve construction, in slip-ring seals and as expansion elements in oil-cooled high-voltage switchgears.
