Diaphragms, elastomer bellows

1. Reinforced rubber diaphragms

Rubber diaphragms reinforced with polyester fabric are produced on the basis of know-how of Constanta-2 LLC.

Reinforcement with glass and polyester fabric allows to dramatically increase the strength without losing the main inherent properties of rubber.

Diaphragms dimensions: up to 1500 mm.

Pressure: up to 5 MPa

Operating temperature: up to 250°С

Material: fabric reinforced special purpose elastomers.

Dimensions of diaphragms and valves for actuator valves: DN 50 - DN 250

Material: elastomers reinforced with cord fabric or steel tabs

3. Rubber bellows

Bellows (‘duster’ is one of the common names in mechanical engineering) are used for protection against contamination and ensuring tightness of machine and machine assemblies. Bellows produced from rubber compounds are used in regulating installations, where these devices operate at elevated temperatures and aggressive gas and liquid environments. Bellows are widely used in installations of regenerative air heaters with lever-mechanical sealing system; for sealing the places of passage of radial and axial plate hangers through the beams of covers. Rubber bellows are used in mechanical seals of water pumps Areas of application: in chemical, food, medical, pharmaceutical, instrumentation, armature and other industries.

4. Fluoroplastic rubber diaphragms

The diaphragms are designed for pumps pumping highly aggressive media. The working side of the diaphragm is protected by a PTFE-4 layer, which provides exceptional chemical resistance. The PTFE and rubber layers are firmly bonded and work as one unit, resulting in excellent performance.
