Rolling rubber diaphragms are special diaphragms shaped like top hats which provide the properties both of bellows and diaphragms.
The rolling diaphragms have deep folding parts, which allow smooth rolling action.
A long stroke is possible, and the effective pressure receiving area will be maintained the same throughout the operation.
Because the Rolling Rubber Diaphragm will move with a rolling action, it will not be necessary to pay special attention to the surface finish, materials, and hardness of the piston and the cylinder.
In addition, these rolling rubber diaphragms can respond to minute pressure variations, greatly contributing to improving the performance of equipment in the air pressure and liquid pressure control fields.
Some of the elastomers for the manufacturing of Elastomeric rolling diaphragms include: Nitrile/NBR, Silicone (VMQ), Chloroprene (CR), Fluorocarbon (FKM), EPDM, Polyacryate (ACM), Perfluoroelastomers (FFKM), Hydrogenated nitrile (HNBR)
We can supply as well Elastomeric rolling diaphragms with 'Special' cloth reinforcement, often available from stock, having the following fabrics as reinforcement:
Nylon/ Polyester/ Cotton/ Nomex
