Vacuum pumpsCore equipment
High-performance vacuum pumps from SMS group are the heart of secondary metallurgical vacuum processes. For both recirculation or tank degassing processes, our vacuum pump technologies are tuned to your specific steel conditions and to your individual plant and production requirements.
Our vacuum pump systems precisely control the rate of pressure reduction from atmospheric level to low vacuum pressure. During the various treatment steps the vacuum level is accurately controlled to match the system’s metallurgical needs.
In order to deliver optimum results high suction capacity, low energy consumption and optimal reliability are essential elements of our design.
Three technologies form the cornerstones of SMS group’s vacuum systems:
- Steam ejector vacuum pumps
- Steam ejectors with water ring pumps Dry mechanical pump systems.
The selection of a specific technology depends on the respective conditions in the secondary metallurgical plant. Availability of utilities, metallurgical needs and the balance of operational and investment costs are basic considerations for our individual, high-performance concepts.
SMS group has decades of pioneering experience in various vacuum pump technologies. In 1956 the first steam ejector vacuum pump for the vacuum treatment processing of liquid steel was built. Since 1960, we have also designed plants with mechanical vacuum pumps.
In 1985 our four-stage steam ejectors replaced the former five-stage version for high cooling-water tem-peratures. For advanced splash control, our RH-SC® with variable steam nozzles was launched in 2000. And in 2006 we introduced our Triple-S-technology for reduced consumption of cooling water.
