Mechanical / hydraulic

  • Design: Vertical, radially split volute casing pump, single entry, single stage, radial impeller. Impeller can be closed or semi-open, both equipped with renewable wearing ring or plate. Standard installation is vertical in non-pressurized tanks. Special executions for very low pressurized tanks are available on demand.
  • Materials:
    • Common materials include: Grey cast iron (JL 1040 / GJL-250), Cast chrome nickel molybdenum steel (CF8M / 1.4408), Tempering steel (F-114 / C45), Hot rolled chrome nickel molybdenum steel (AISI-316L / 1.4435), Cast chrome steel (CA6NM / 1.4313), Chrome nickel steel (AISI-431B / 1.4057), Special PTFE (TFM, Graphite charged), Steel (St 37.0, F-111 / C15).
    • See the official PDF for exact tabulated material variants for Volute Casing, Pump Cover, Shaft(s), Impeller, Pedestal, Wear Rings, Shaft Sleeve, Friction Bearing bush, Discharge Pipe, Intermediate pipe, and Base Plate.
  • Shaft Seal:
