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.

Our Logistics – Your Service
Innovative, environmentally friendly and efficient
In addition to innovative techniques, our logistics has 2,870 sqm of process surface. We have the world's first AutoStore storage system on two levels. Both grits are connected to each other by means of special lifters. In total, up to 31,000 containers can be stored in a very confined space. Due to this subdivision, up to 240,000 storage areas can be managed most efficiently.
