Horizontal, self-priming, multi-stage side channel pumps with open vane wheel impellers handling entrained gas during normal duty. A special bearing was developed for compensation of the axial forces occurring in case of high nominal pressures.
Pumps of the series ASH were developed for handling liquid gases with vapour pressures of up to 80 bar. The high admissible nominal pressure and the optimum operation properties of the material combinations selected resulted in multiple application of this series, especially for handling carbon dioxide. They are successfully applied in processes and installations for the production, storage and transportation of CO2, in supply plants, measuring, regulation and decanting equipment, fire-extinguishing and inert installations, in CO2 drying and CO2 cleaning plants, for production of dry ice and neutralizing of alkaline waste waters.
