products - Diaphragms
    |
Introduction
Diaphragms are used as flexible seal for a wide range of fluids that can also transfer forces to and from a fluid.
Applications for diaphragms include pressure switches, flow regulators, pumps, and fluid control valves.
Diaphragms can be supplied in a wide range of elastomers to suit different end use service requirements.
Within the Gulf Rubber group is a specialist manufacturing plant, Tumedei
S.p.A. Rubber Engineering. Tumedei manufactures high performance fabric
reinforced diaphrams in Italy. For more information please go to www.tumedei.it
