Description

The NBD numerical volumetric 2K dispenser for two-component materials uses reciprocating piston pump technology. The NBD is a combination of two NVD dispensers with a mixing chamber. The dispensers can handle liquid and viscous materials.

The NBD has no seal in the ceramic piston-cylinder system resulting in reduced maintenance.

Furthermore, and according to the needs, the NBD is delivered as turnkey solutions using one of our standard dispensing platforms including: MRC500, TR300, OEM, and station.

The main features of our NBD numerical volumetric two-components dispenser include:

  • Automatic volumetric dispensing of two-component liquid or viscous products down to small volumes
  • Volumetric dispensing without valve
  • Piston and cylinder made of ceramic
  • Controller
  • Material pre-heating possible

Typical dispensing applications:
Gluing, potting, conformal coating, dot and line dipsensing and lubrication.

Typical dispensing materials:
Sealants (e.g. silicone, MS-polymer, polyurethane), adhesives (e.g. anaerobic glue, epoxy resin, UV-Acrylat), gap fillers, grease and oil.
