Simrit Displays Aerospace Engine Sealing Portfolio at 49th International Paris Air Show

Aerospace, General, Markets, Metal Seals, Specialty Sealing Products,

LE BOURGET, France, June 20, 2011 – To showcase its extensive engineering and advanced technology expertise, Simrit will demonstrate its portfolio of aerospace engine sealing solutions during the 49th International Paris Air Show held in Le Bourget, France from June 20 to 26.  The product line – consisting of brush, segmented, compact mechanical and ACTISEAL® seals – was specially developed to meet the precise needs of several aerospace applications, including engines, rockets, and space vehicles and equipment.

The demanding operating conditions encountered in today’s gas turbine engines, along with increasing environmental concerns, have created the need for an alternative to conventional labyrinth seals. As a result, brush seals were developed to accommodate the radial movements of the dynamic rotor shaft due to the flexibility of their bristles. Additionally, the free length and angle of the bristles, as well as the wire diameter, can be customized to the given applica­tion to optimize seal stiffness, resulting in low wear and leakage, and a potential reduction in fuel consumption.

Designed for gas sealing applications primarily in jet aircraft engines and gas turbines, Simrit’s circumferential segmented seals are ideal for high-performance equipment where large axial shaft movements, space requirements, weight reduction and / or efficiency are major concerns. Containing a set of segmented carbon rings that contact the shaft (or runner) to form a circum­ferential dynamic seal, they also serve a wide range of applications in rotating machinery, such as compressors and blowers.

Compact mechanical seals are stationary, “face” type seals designed for a variety of applications, including aircraft engine accessory gearboxes and main shafts, hydraulic pumps, starters, compressors, industrial generators and other high-speed rotating machinery. Uniquely, Simrit offers custom-engineered seal configurations, as well as previously developed and proven materials and designs to meet customers’ varying needs.

Simrit’s static metal ACTISEAL seals are used between surfaces that have little or no movement to prevent the passage, flow or leakage of a gas or fluid. Offering a substantial track record of success in solving leakage problems, the ACTISEAL line consists of three solutions, ACTISEAL–C, ACTISEAL–E and ACTISEAL–W, to match varying customer needs.

Additional information about Simrit’s jet engine seals will be available at the Simrit booth (#C19) located in hall 3 at the 49th International Paris Air Show held in Le Bourget, France from June 20 to 26 or visit www.simrit.com.

Simrit E454 O-ring Sealing Systems Continue to Solve Critical Problems in Commercial Aircraft Hydraulic Systems

Aerospace, Markets, O-Rings,

ELGIN, Ill., June 13, 2011 – Customer and testing data has proven that Simrit’s E454 EPDM (ethylene-propylene rubber) O-ring sealing systems outperform competitive O-rings in critical commercial aircraft hydraulic systems. Manufactured to the highest possible quality and extensively tested, the phosphate ester fluid hydraulic sealing systems are expected to perform flawlessly for years in primary and secondary flight controls, and braking systems of commercial aircrafts.

“Based on our test results and simulated component tests, we knew that the E454 material was a quantum leap over competitive materials when we commercialized it in 2006,” said Dr. Robert W. Keller, materials development manager, Simrit. “Today, our E454 compound not only meets the demanding requirements of NAS-1613 Rev. 5 in all commercially available phosphate ester hydraulic fluids, but it significantly outperforms competitive materials in both simulated and actual application systems.”

 The hydraulically boosted primary and secondary flight controls are critical to modern commercial aviation, as they provide the basic abilities of the aircraft to fly, turn, climb, descend and stop. As a result, all aspects of the systems – including the sealing technologies – are vital to passenger safety.

“To ensure the consistency and quality of the product, we only manufacture the E454 compound at our Santa Ana, California AS9100 and Nadcap-certified facility,” said Vinay Nilkanth, vice president of global sales, aerospace, Simrit. “This allows us to manufacture the highest-quality products for our customers’ crucial needs.”

As a result of its superior composition and performance, several major commercial aircraft manufacturers and suppliers have chosen the material over its competitors. As an example, Simrit’s E454 O-rings were chosen exclusively by a major manufacturer of flight control hydraulic power units and were evaluated with the latest Type V (AS1241) phosphate ester hydraulic fluids in a wide body commercial aircraft. After several thousand hours of service and several hundred complete flight cycles, the Simrit E454 O-rings were examined and found to be in “as new” condition in terms of dimensions and physical properties. Competitive O-rings had shown issues with wear and compression set under similar circumstances.

Additionally, a major manufacturer of components for phosphate ester hydraulic flight controls switched all of their components to Simrit E454 O-rings to solve leakage issues on a variety of commercial airliners. The Simrit O-rings were selected after the competitive O-rings were not able to perform despite several re-designs and two years of trial-and-error evaluations.

Additional information about Simrit’s E454 O-rings and sealing systems will be available at the Simrit booth (#C19) located in Hall 3 during the 49th International Paris Air Show held in Le Bourget, France from June 20 to 26.
