One of our highlights is the still functional circulation pump. It was needed to maintain the high-pressure gas cycle in the Haber-Bosch process.
Characterization: The circulation pump is a standing single-stage reciprocating compressor.
Manufacturer: Esslingen machine factory
Year of construction: 1925
Operational use: Ammonia synthesis at the Leuna works, in use until 1986
Function: Maintenance of the high pressure gas cycle
The pump is functional and can be demonstrated to you by our trained museum staff. It is best to arrange a tour for this.
