The SEM pump offers a simple and efficient way of conveying concrete through pipelines, utilizing the unique pneumatic screw system.  There are no mechanical working parts in the pump.

• SAVES LABOUR
  No more manhandling of concrete up and down inclines or shafts.  The concrete is pumped through the pipeline directly into the shutter - 100m horizontally or 18m vertically.
  
  
• INCREASED PRODUCTION - DECREASED TIME
  Panmixers are faster than conventional drum-mixers.  The pump will place concrete as fast as the mixer can produce.
  
  
• NO TIME WASTED IN SETTING UP EQUIPMENT
  The unit is towed into place, the pipeline coupled up, the air-feed connected and the operation can start.
  
  
• FLEXIBILITY:
  The pipeline can easily be carried through narrow openings and into inaccessible areas.

• LOW REBOUND
  only 5% to 15%.
• NO DUST PROBLEM
  SEM wet mix system reduces dust count to safe proportions.
• SKILLED NOZZLE OPERATOR NOT REQUIRED
  nozzle operator has minimal influence on quality of shotcrete, because of premixing.
• LOW AIR COMSUMPTION
  Very economical compressed air requirements.
  
• UNIFORM QUALITY - GOOD AHESION
  ensured by wet mix.
  
• NEGLIGIBLE MAINTENANCE
  simple, and open design panmixer and non-mechanical pump reduces maintenance to general cleaning of equipment.
