Patent number: 8608172Abstract: A bulkhead seal includes a housing configured to be attached to a bulkhead about a shaft and defining an annular recess. An annular diaphragm seal is rotatably disposed in the annular recess of the housing and about the shaft. A plurality of orifices extend through the annular diaphragm seal to prevent air pressure differentials from locking the annular diaphragm seal with respect to the housing. A lip seal is provided on each side of the annular diaphragm seal. Each lip seal includes a seal portion disposed to seal the orifices in the presences of liquid.Type: GrantFiled: April 13, 2010Date of Patent: December 17, 2013Assignee: Mide Technology CorporationInventors: Marthinus van Schoor, Steven Klepper, Andrew Cutler

Patent number: 8419020Abstract: A fluid activated shaft bulkhead seal system includes an annular carrier fixed with respect to a bulkhead and about a shaft extending through the bulkhead and the annular carrier. The annular carrier supports a pair of lip seals each of which defines an outwardly facing pocket and a lip portion spaced from the shaft and a portion abutting the carrier. A foam body is disposed in the pocket of each lip seal. Each foam body includes a gel material configured to expand in the presence of fluid urging the lip portions of the lip seals into contact with the shaft to seal the annular carrier with respect to the shaft. An annular retainer is mated to each side of the annular carrier for retaining the foam body in the pocket of each lip seal.Type: GrantFiled: July 28, 2010Date of Patent: April 16, 2013Assignee: Mide Technology CorporationInventors: Marthinus van Schoor, Christopher C. Ludlow, Steven A. Klepper, Andrew M. Cutler

Patent number: 7828299Abstract: Systems and methods associated with a fluid-activated shaft seal are provided. The systems, which feature multiple components, include a support component defining an exterior surface, a carrier component including an interior surface to slideably engage the exterior surface of the support component, and a seal disposed relative to the carrier component. The seal includes a lip portion and a fluid-responsive gel material that expands when exposed to a fluid to urge the lip portion towards or into contact with a shaft. The gel material contracts in the absence of the fluid to form or increase the size of a gap between the shaft and the lip portion. Methods of assembling and installing such a system are also described.Type: GrantFiled: June 6, 2008Date of Patent: November 9, 2010Assignee: MIDE Technology CorporationInventors: Marthinus van Schoor, David Gilbert, Andrew Cutler, Steven Klepper
