Successful utilisation of mechanical vacuum pumps in steel degassing

Mechanical dry vacuum pumps are increasingly replacing traditional steam ejectors in vacuum secondary steelmaking plant applications because of their ‘greener’ credentials and proven record of reduced cost of ownership by as much as 97% compared to steam ejectors. This calculation takes into consideration the cost for production of steam, water circuit pumps, maintenance and disposal of condensate versus lower power consumption of mechanical pumps with its maintenance cost.
