Our goal is to minimize your ongoing wet oil seal costs, unscheduled downtime and resulting productivity losses. Currently, there are thousands of centrifugal compressors installed globally that predate advanced Dry Gas Seal (DGS) technology and run with wet oil seals, which require costly maintenance and cause parasitic power losses due to oil shear and drag.
The heart of the DGS is a pair of rings. A stationary ring is held against a rotating ring by spring pressure. The contact face of the rotating ring incorporates special fil-riding geometries in the form of groves or tapered lands on the outer portion.
DGS designs:
Siemens Energy, as the compressor OEM, is best suited to provide a sealing solution that ensures the best overall compressor performance and maintenance, from a single source. Applicable to all OEM and non-OEM centrifugal compressors.
Our innovative sealing solution eliminates the need for a seal gas booster, protects dry gas seals from contamination, reduces maintenance and downtime costs.
Seal Protect sits between the dry gas seal and process side seal, remaining open during operation to prevent contamination. In static or low-speed conditions, it ensures only clean, dry process gas reaches the Dry Gas Seal.
Benefits of Seal Protect include:
Seal Protect is compatible with most new compressor packages and can be retrofitted into existing units for improved reliability.
