What is a cold glue delivery unit?
A cold glue delivery unit (also called a cold glue supply system or cold glue pump unit) is a pump connected to the glue container that delivers single-component, room-temperature adhesive – such as PVAc, dispersion glue or contact adhesive – at steady pressure and flow straight to the point of application: a hand gun, dispense valve, glue roller or an automatic line applicator. Unlike hot melt, cold glue needs no melting, so there are no heaters and no warm-up time.
Elister is the official Graco distributor in Estonia and supplies, installs and services Graco cold glue pumps and delivery units for the wood, furniture, paper and packaging industries.
How a cold glue delivery unit works
- Container: glue is drawn directly from the original package – cartridge, pail or drum. On larger containers a follower plate pushes the material into the pump and empties the container almost completely.
- Pump: a pneumatic (air-driven) or electric piston pump keeps the glue line at stable pressure, even over long hose runs.
- Distribution: one pump can feed several workstations, dispensing stations or proportioners.
- Application: hand gun (e.g. Graco Flo-Gun), automatic valve or glue roller.
Technical data by model
Graco DynaMite – compact delivery unit for small containers
- Containers: from 300 cc cartridges up to 1-gallon (~4.5 l) containers
- Drive: Graco NXT air motor (pneumatic)
- Best for: workshops, edge gluing, profiles, small glue volumes
Graco DynaMite cold glue delivery system →
Graco Check-Mate – pump and supply system for pails and drums
- Material: medium to high viscosity one-component adhesives, sealants and fillers
- Containers: pails and drums; available as a stand-alone pump or as a supply system with follower plate
- Construction: carbon steel or stainless steel (stainless models for waterborne glues)
- Drive: pneumatic air motor
Graco Check-Mate cold glue pump →
Graco Dura-Flo – high pressure with stable flow
- Containers: 5–20 l pail or drum up to 200 l
- Material: medium to high viscosity glues (PVAc, contact adhesives)
- Drive: pneumatic; high pressure without compromising flow stability – suits lines with long hose runs
Graco Dura-Flo cold glue pump →
Graco E-Flo SP – electric supply pump
- Drive: electric motor – no compressed air required
- Control: precise pressure and flow control, real-time performance data
- Best for: automated production lines where process control and data matter
Graco E-Flo SP electric cold glue pump →
Graco T2 – 2:1 transfer pump for 200 l drums
- 2:1 pressure ratio; PTFE seals, stainless steel wetted parts
- Container: standard 200-litre drum, quick-release adapter
- Best for: feeding viscous two-component materials (e.g. Graco Reactor)
How to choose a cold glue pump
- Glue volume and package: cartridge or small can → DynaMite; pail or drum → Check-Mate or Dura-Flo; high continuous demand → drum system with follower plate.
- Viscosity: the thicker the glue, the more pressure and the larger the pump required.
- Waterborne glue: choose a model with stainless steel wetted parts.
- Hose length and number of workstations: long lines or several stations need higher pressure (Dura-Flo, Check-Mate).
- Air or electric: if compressed air is limited or you want process data, choose the electric E-Flo SP.
Applications
- Wood industry: plywood, board and panel gluing, edge gluing, glulam
- Furniture industry: carcass, frame and dowel joint gluing – see also adhesives and sealants for furniture manufacturing
- Window and door manufacturing
- Paper, board and packaging – see cold glue equipment for the printing industry
- Glue transfer to dispensing stations and container filling
If you need melted adhesive, see hot melt gluing equipment. For precise metering of two-component adhesives and sealants, see sealant and adhesive dispensing. All gluing solutions are listed under gluing equipment.
