Applying gasket sealants? Filling bottles with expensive perfume? Applying "Happy birthday" to a cake? What these, and many other, applications have in common is a need for accurate dosing of materials for automated production – and that means no blobs, no drips and consistent line thickness with no overlaps.

The Robo-Dispenser from Netzsch Nemo Pumps is designed to provide exactly this (see Plate 3). Its precise and consistent dosing of media can provide significant improvements in material waste reduction, unit rejection and productivity for a wide range of applications in the automotive, electronics, chemical, mechanical engineering and processing industries.

The Robo-Dispenser uses a Netzsch Nemo positive displacement pump that ensures pulse-free delivery. The valveless progressing cavity pump offers considerable advantages over conventional units, not only for product transfer but also for direct dosing. The discharge amount is constant even with varying operating conditions such as pressure, temperature and viscosity. System-specific valves are therefore not necessary. The Robo-Dispenser eliminates the dripping or stringing that causes accumulation of the medium at the start and finish of lines and at overlaps. It also ensures uniformity of application when changing from straight lines to curves.

The Robo-Dispenser offers materials savings of up to 50 per cent over conventional dosing systems and provides precise dosing of viscosities from watery to pastes. It also features airtight construction to eliminate hardening of the media in the pumping area and pollution of the environment by solvents. Compressed air operation reduces costs and noise.

Light weight and compact dimensions allow the Robo-Dispenser to be installed in hand-held and robotic machines. Cartridges and special barrel pumps are available to transfer from 20l to 200l barrels of medium to the dispenser.
