Regenerative turbine pumps

TOE-GN/GA/GI, TOE-MN/MA/MI

Heat transfer pumps with radial impeller in modular design with mechanical seal or magnetic coupling
in six different versions with two different bearing brackets (360 and 470).

Advantages

  • Interchangeability of many parts at all series
  • Same hydraulics for TOE-GN / GA / MN / MA series
  • Same hydraulics for TOE-GI / MI series
  • Synthetic heat transfer media with low viscosities are delivered without any problems up to 350 °C
  • Hydrodynamically lubricated sleeve bearing in SiC
  • Low-wear impeller side chamber
  • Pumps with mechanical seal
    Mechanical seal casing with antivortex baffle for the prevention of gas bubble rotation,
    distortion-resistant casing cover with cast integral fins for the accommodation of insulation pads
  • Pumps with magnetic coupling
    Wide range of separating can and bearing sizes for optimum adjustment to delivery data and minimization of magnetic power loss,
    transferable torques up to 500 Nm possible
