Deminas Kammprofile gaskets

are recognized as a problem solver for heat exchangers, large vessels, and equipment that experience excessive movement due to thermal expansion. The Kammpro provides one of the tightest seals combined with superior load bearing characteristics. Kammpro gaskets consist of a sealing core metal with or without guide ring. The sealing core is a solid metal gasket with concentric serrations on both sealing surfaces and faced with soft material such as flexible graphite, EPTFE,. It is the preferred design when needing improved performance at low seating stresses. The simultaneous actions of a high compressibility facing material on the outside of the grooved metal in combination with limited penetration of the tips of the solid metal core enhance the interaction of the two materials. This allows the component to perform individually to their optimum capabilities.
It is available in different materials and shapes such as non-circular shapes which produced efficiently with extreme accuracy to fit various bonnet connection shapes, also it can be custom engineered to fit various applications. The suggested flange surface finish for Kammpro gaskets is 125-250 RMS.

Kammpro style DEK1 is manufactured without a guide ring for tongue and groove, or recessed flange applications such as Male and Female. It is typically used in heat exchanger applications and applied as an upgrade to double jacketed gaskets especially when lower load is needed. It is highly suggested to have the nubbin (if present) machined out when applying Kammpro DEK1 in heat exchanger applications.

Kammpro style DEK2 is constructed with an integral guide ring for aligning purposes. It is suggested to be used in raised face flanges. The sealing core is designed and sized per EN-12560-6 spec and depending on the flange specification the guide ring is sized to fit properly.

Kammpro style DEK3 utilizes a loose fitting guide ring. This popular design is preferred to be used for nominal pipe size and pressure class raised face flanges and is used in equipment with excessive radial shear characteristics, thermal cycling, and expansions. The sealing core is designed per EN-12560-6 spec and the guide ring is sized to suit the flange specification.
