Introduction 
  The KTM pump performs three functions simultaneously
  suction, mixing, pressurization ideal for DAF and
  liquid-gas applications. Its reliable performance
  results in a highly stable overall system.
 
  
Features for DAF Applications
 High rate of suspended solids removal 
 Supplying a highly dense microbubble output
 Highly consisten dissolved air flotation
 Fine adjustments not necessary when operation or start up
 Easily retrofit to pre-existing systems
 Small installation footprint 
 Minimum power consumption
 Low power required for KTM (no compressor required) 
 Easy maintenance and minimum operational cost
 Compact and simple pump structure
 Quiet operation
 No compressor, level controls, saturation tank required
