Slim pump FLOTRONIC 500 mini
Technical Information

The ONE-NUT Concept

  • The inside out concept allows fluid to pass between the diaphragms, directly through the centre of the pump. Air pressure operates on the outside. The benefits are:
  • Longer lasting diaphragms
    A significantly reduced stroke length allows use of thicker / stronger PTFE diaphragms as standard. Nitrile, Viton® and EPDM are also available.
  • Faster maintenance
    Fifteen minutes to change diaphragms by the removal of just one nut and without disconnecting the pump from the pipework.
  • Lower cost spares
    Less than half the quantity of spare parts than any equivalent pump and interchangeability of most air system parts between different series of pumps.
  • No lubrication
    A unique, patented air system incorporating a bolt on spool valve, including manual override buttons, eliminates costly internal air mechanisms and mid position stall normally associated with Double Diaphragm Pumps.
  • Greater inherent safety
    Plastic parts are kept within metal containment and potential leak paths are reduced to a minimum. Even under ATEX conditions pumps can be maintained ‘in the zone’ up to Zone I using anti-static PTFE-faced diaphragms.
