Certain types of adhesive tend to absorb ambient gas or air when pres-sure is applied. During the dispensing process the gas is then released and bubbles form in the media. To avoid these negative effects, marco provides equipment preventing any contact between the medium and gas or air.A pneumatic high pressure pump is available for media which require a higher dispensing pressure. Depending on the type, pressure on the medium can be amplified by a factor of 3 or 12. For media dispensed in the standard pressure range, a special cap can be fitted on the cartridge.
The cap has a piston which transmits the pneumatic supply pressure to the medium without contact to the compressed air.
