Inflatable Seals

1. Horizontal or Vertical sliding doors.
2. Hinged doors with flush thresholds for easy personnel or equipment access.
3. Large fabricated doors or other closures where it is impractical to machine the sealing surfaces to accommodate conventional seals and gaskets.
4. Processing equipment where rapid sealing and unsealing is required.

Doors and other closures can be positively sealed by using Pneuma-Seal inflatable seals. The seal is inflated with air or other fluid by a pressure-regulated supply system (which can also be furnished by us). When pressurized, the inflatable seal conforms to uneven surfaces and provides an efficient, reliable barrier to dust, moisture, contaminants, and/or pressure differential.

Operating pressures are usually in the range of 10 to 35 PSI but some of the inflatable seals can be designed to operate at lower pressures, in the order of 5 PSI or less, or at higher pressures of 100 PSI or more. Expansion capabilities, the ability to close a "gap", vary from cross section to cross section. Large "gaps" may be accommodated but it should be noted that as the gap increases, the pressure required to seal against a given pressure differential increases, thereby decreasing the inflatable seal’s flex life.

TYPICAL CONFIGURATIONS | SPECIAL CONFIGURATIONS

Inflatable Clamps Using Pneuma-Seal as an inflatable clamp provides uniform controlled pressure to firmly clamp pieces together during bonding operations or to hold pieces in place during machining or cutting operations. Typical applications include the bonding of airframe components and stopping large pharmaceutical bottles on a conveyor line.

Inflatable Actuators
The expanding Pneuma-Seal moves and repositions other components which exert pressure to actuate switching devices, to open and close air or hydraulic passages, or to clamp mechanical components. In a typical application, the inflatable actuator effects the desired motion and mechanical springs return the components to their normal open or closed position.
