CBD continuous flow two-components dispenser

The CBD continuous flow volumetric dispenser for two-component materials uses continuous flow progressive cavity pump technology. The CBD is a combination of two CFD dispensers with a mixing chamber. The dispenser is highly versatile capable of dispensing low-viscosity, high-viscosity and filled materials.

The CBD are available in several volume and flow rate sizes. The rotors, stators and pump housings include
a variety of materials to provide mechanical and chemical compatibility with a broad range of materials. Several motors, controls interfaces and mechanical connections are also available.

Furthermore, and according to the needs the CBD is delivered as individual component for integrated solutions, with mta standalone numerical controller or as turnkey solutions using one of our standard dispensing platforms including: MRC500, TR300, OEM, and station.

The main features of our CBD  head include:

  • Automatic or manual dispensing of two-components liquid or low-viscosity, high-viscosity and filled materials
  • Volumetric continuous flow dispensing thanks to a rotating displacement system
  • Simple setting of the dispensing parameters via numerical controller
  • Broad flow range
  • Various motor, pump and rotor/stator sizes
  • Rotor available in hard chrome plated or DLC coated
  • Different elastomers for stator
  • Housing in stainless steel or PEEK
  • Flow rate is directly proportional to drive speed
  • Material pre-heating possible
