Plate-fin heat exchangers can be used for air-to-air, air-to-liquid, or liquid-to-liquid cooling applications. These units are made up of vacuum brazed aluminum fins to an aluminum plate or aluminum fins to a titanium plate. Senior Aerospace can also integrate bellows coolant reservoirs/compensators, thermal actuators, or other cooling system components.

The all welded stainless steel construction of our reservoirs and accumulators eliminates the problems associated with elastomeric seals in traditional piston or bladder devices. The welded bellows construction provides maintenance free service, high reliability, and long life. These units are ideally suited for, and have a long pedigree on, commercial and military aircraft, ground vehicles, and weapons systems.

With an MTBF of 50,000 hours, this compressor/pump has become the standard for commercial aircraft applications that demand high reliability and long life. These compressors are used to pressurize the potable water system. Also, configured as a vacuum pump, these units are used on vacuum waste systems.

Our Met Bel vacuum pumps and compressors are found in applications where absolute reliability and consistent performance are fundamental requirements. Versatile, durable and maintenance-free, they perform as post accident monitoring compressor in nuclear power plants, exhaust emission analysis pumps in automotive plants, and other applications where contaminents must be under constant and total control, and where reliability is of utmost importance.

Bellows kiss seals provide a flexible interface for engine nacelle applications. Available in stainless steel or Inconel, these seals can withstand the extremes of temperature, pressure, and vibration found on most commercial and military aircraft engines.

For use in engine, gearbox, and pump applications, the bellows mechanical face seal can withstand the extreme operating conditions found in the most demanding engine environments. These components provide high reliability and long life.

The welded metal bellows fuel drain can withstand the extreme operating environments found on today’s military aircraft. Available in all welded stainless steel or Inconel, this tough drain provides high reliability and long life.

The wax filled bellows thermal actuator provided precise actuation for a specified temperature range. The all welded stainless steel construction allows the actuator to withstand harsh operating environments and provides high reliability and long life.

Used in the anti-skid system for large commercial and military aircraft, the couplings main function is to provide a flexible interface between a speed indicator transducer and the hub of the landing gear wheel. The transducer produces a voltage that represents the speed of each individual wheel on the landing gear. In a typical landing the tires accelerate from zero to 140 mph in less than a tenth of a second. The landing of an aircraft is an extremely demanding environment for vibration, shock, heat and acceleration.

These sensors use a welded metal bellows in combination with an LVDT for sensing pressure. This unique design allows for high accuracy over a wide range of temperatures from -65F to 450F and pressures to 500 PSID. This same technology may be used for flow sensing applications as well. These highly reliable units have a demonstrated reliability of over 2 million hours MTBF.

Aircraft engine fuel controls require precision bellows for pressure and temperature sensing. These assemblies must tolerate the harsh engine environment, have long cycle life, and provide a precise and repeatable response to changes in pressure or temperature.

Purge Bellows

Flexible, all metal, joints and couplings for vacuum and inert gas purge applications. Designed to accommodate assembly misalignments with minimum axial, lateral, and angular spring rates

Dynamic Seals

Designed for long cycle life (1 million cycles or more) and of materials able to withstand harsh environments, i.e., etch processes. Diameters (AM350, High Nickel Alloys) can range up to 450mm or greater with minimal stroke length.

Using our advanced metal bellows technology, PRIME MOVER is a unique linear actuator that provides superior reliability and maintenance free performance. PRIME MOVER provides actuation across a pressure boundary with zero leakage, operates in harsh environments and in temperature extremes.
