Solutions for regenerative energy production
Tidal, river, solar, and geothermal power stations exhibit specific operating conditions that represent very different challenges to sealing technology. Whereas hot, toxic thermal oil can be securely sealed in solar thermal power stations, geothermal applications need to control hot and strongly abrasive thermal water under high pressure.
Many years of know-how as well as intensive research and development is the basis EagleBurgmann uses to provide innovative seal solutions for the most diverse applications - for already established technologies as well as for future challenges.

EagleBurgmann solutions for water power plants

A seal for a shaft diameter of 550 mm (21.65") – an absolutely thrilling dimension. In close cooperation with the customer, EagleBurgmann developed the durable and robust VGH300S1/560 mechanical seal to help increase the overall efficiency of the pump in an Austrian reservoir power plant.
Read on for the entire case study.
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).
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.
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.
