Multi Effect Distillation

Desalting water through evaporation techniques

The Multi Effect Distillation (MED) process is based on iterative evaporation-condensation processes in several stages under vacuum conditions, using residual steam from an adjacent power plant as heating media for evaporation. The main challenge for the pumps is low NPSH available. Typically end suction, low NPSH pumps are required. For larger capacities axial split casing pumps are also used.

  • AHLSTAR A range
    AHLSTAR A Range long and close coupled end suction single stage centrifugal pumps are used for demanding industrial applications to ensure process reliability, high efficiency and low operating costs.

  • SMD axially split casing double suction pump
    The SMD pumps are designed for a wide range of raw, clean, sea and brackish water applications. To meet the demands of the individual applications, the SMD benefits from a best-in-class hydraulic design that is combined with two specific mechanical envelopes; Standard SMD and Configured SMD.

  • ZE/ZF end suction pump range
    The ZE/ZF are ideal pumps for arduous industrial applications handling clean, cold or hot liquids, including hydrocarbons and light chemicals.
