    Key features

  • Cast aluminium gear housing - maximum strength and stiffness with minimum weight
  • Speed reduction is achieved using inline concentric planetary gears designed for 24 hour continuous duty - AGMA service factor of 1.5 or greater
  • Large output shaft bearings with an average life expectancy in excess of 100,000 hours under continuous full load conditions - longer allowable shaft lengths and ensures a long operating life
  • Bearings and gears are grease lubricated and sealed for life to ensure maintenance free and trouble free operation
  • Motor is spigot mounted directly onto the speed reducer to ensure consistent alignment of the high speed coupling. A flexible motor coupling is used to connect the electric motor to the input shaft of the planetary gear in order to dampen out shock torsional loads and increase motor bearing life
  • All openings are fitted with guards in accordance with current EU Directives
  • All units in the Lightnin ECL Range carry the CE mark in accordance with European Community Legislation and are ATEX certified where appropriate.

    Note: These mixers can be fitted with 3 gear types (1:1, 5:1 or 6:1) Additionally motor input speed can be varied and changes can be made to the shaft and impellers etc. to accommodate different tank ratios / geometries. Tailored mixers can be provided - generally for the same price - if the customised solution falls within the design parameters... Please include the basic tank size and geometry (i.e. shape, orientation, height & diameter) in the additional information section of your order. If the mixer is not intended for a biodiesel application, please provide the process details as we can almost certainly provide a tailored mixing solution to suit!
