Ultra reliable delivery pumps for water based/cold glues
Our cold glue delivery systems fall into one of two categories:
Basic pressure tanks use compressed air to deliver adhesive to the applicator. The adhesive line pressure is equal to the air pressure supplied to the tank. A pressure tank is the simplest and most cost-effective solution for low-speed jetting and spray applications.
Common tank sizes are:
- 1 gallon (3.8 litres)
- 5 gallon (19 litres)
- 10 gallon (38 litres)
An example of one such installation can be found in the food industry. A fine spray of cold glue is applied to the outer paper wrapper of a chocolate bar. This is then folded around to seal the final layer of packaging.

Please contact us for any assistance in specifying your cold glue pump.
Piston pumps amplify incoming air pressure to provide a greater adhesive line pressure. The ratio of incoming air to adhesive pressure is 1:12. The high pressure piston pump is suitable for high speed intermittent applications such as envelope manufacture. The piston pump simply drops on to your cold glue container.
The piston pump can be signalled using an E/P valve to regulate the incoming air. This enables one of our pattern controllers to accurately meter the volume of adhesive being applied.
Multiple application heads can be fed using one piston pump.
