Diaphragms Rolling Diaphragm RMG

Rolling Diaphragms RMG are highly flexible, thin-walled diaphragms with a fabric reinforcement on the pressure side. They act as flexible movable partitions providing hermetic sealing against two chambers. At the same time, they can perform a stroke movement that is perpendicular to the clamping plane. Due to its thin-walled design and the ratio to the diameter and large height of the diaphragm, the RMG has following advantages: 
  • a virtually constant  inherent resistance,
  • large stroke length in relation to the diaphragm height and
  • a constant effective area throughout the stroke.
Due to their advantages, Rolling Diaphragms are particularly used in process measurement and control technology. These can also be obtainable without fabric reinforcement as special designs. Our technical consultants will gladly assisit you in your product development.
