Split seal for hydroelectric applications

EagleBurgmann provide successful and durable sealing solutions in hydroelectric applications. For example: An EagleBurgmann HGH200S1/375-E1 split seal has been in operation for more than 10 years at the Sao Joaquim hydroelectric plant in Brazil.

Operating conditions: p = 2.5 bar (36.25 PSI); t = 30 °C (68 °F).

Seals and systems for CSP

An EagleBurgmann SHV mechanical seal is installed on an Ensival feedwater pump at the Gemasolar power plant in Fuentes de Andalucía (Seville, Spain). A MAA2150 magnetic separator and a WDK5150 heat exchanger were supplied.

Operating conditions: t = max. 330 °C (626 °F), p = 117.38 bar (1,702 PSI), n = 2,970 min^-1.

Stern tube seal in a turbine

EagleBurgmann provide successful and durable sealing solutions in hydroelectric applications. For example: A 4600 stern tube seal in a VA Tech Hydro CAT compact turbine ran for more than ten years at the Sylvenstein power plant in Bavaria before the first inspection took place.
