Which Dispensing Gun for Which Cartridge
The cartridge size decides the dispensing gun. A 50 ml cartridge takes a DM-50, DP-50 or DB-50, and a 400 ml cartridge takes a DM-400 or DB-400.
Five Guns, Two Cartridge Sizes
Fluid and Pasty products in cartridges need a dispensing gun. It pushes the two components through the nozzle, where they mix. The size of the cartridge decides the gun, 50 ml for standard products and 400 ml for XL products. You mix Manual Putty products and XL products in bottles or cans by hand, so they need no gun.
| Gun | Drive | Cartridge |
|---|---|---|
| DM-50 | Manual | 50 ml |
| DP-50 | Pneumatic | 50 ml |
| DB-50 | Battery | 50 ml |
| DM-400 | Manual | 400 ml |
| DB-400 | Battery | 400 ml |
Manual, Pneumatic or Battery
The DM-50 manual dispensing gun is the one you find in the cases. For more repetitive use, a DB-50 or DB-400 battery gun suits the job. The DP-50 is the pneumatic version for 50 ml cartridges.
Load a Cartridge
- Push the trigger to draw the pistons back.
- Insert the cartridge with the key at its base facing down.
- Remove the cap with a quarter turn to the left.
- Slide the notch of the nozzle into place and lock it with a quarter turn to the right.
- Squeeze the trigger until the two components mix in the nozzle, and check the test drop.
After the Impression
Unscrew the nozzle, put the original cap back on the cartridge, and store the dispensing gun. You can use an opened cartridge until the expiration date printed on it.
