Graphite Steam Jet Vacuum Pumps for More Energy Efficiency
In recent months, a major European chemical company has modernized and optimized several existing GEA steam jet vacuum pumps used to extract aggressive gases and vapors. In the process, the porcelain jet pumps were replaced by jet pumps made of Diabon graphite without having to modify the complete vacuum units. Within a few days, the units were ready for operation again.
In this project, the focus was on energy savings and operational reliability. GEA was able to determine the exact equipment design for the vacuum systems through simulation models and tests on its own test bench. The retrofit optimized the performance of the vacuum systems for the process and reduced the energy consumption of the pumps by more than 30 %.
For the retrofit of complete vacuum systems without on-site modifications, GEA offers a complete service package: from the inspection of the vacuum unit, support to determine the performance data, engineering and execution to commissioning. During the retrofit, as many components as possible are reused, and connection joints and installation dimensions remain unchanged. Capacity is optimized according to customer requirements and changeover times are kept as short as possible.
