The Widoberg High Velocity spray guns are made for the intermittent spraying of highly abrasive polishing emulsions and lubricants. The spray volume can be regulated between 0.2 and 6 cm3. Up to 25% less material is used compared to other types of application systems.
The spray guns are operated with compressed air and controlled by a solenoid or foot operated valve. When the piston is actuated with compressed air, the plunger is pushed into the cylinder. Due to the extreme ratio between piston and plunger, an overpressure is built up inside the gun, the needle valve opens and the material will be ejected through the nozzle. The high velocity of the shot enables the emulsion to cut through the air turbulences caused by the wheel rotation and to penetrate the mop. A knob allows a precise adjusting of the shot quantity.
There are two basic models available: HDP-II and WIDO-SPRAY.
The HDP-II model has a higher pressure ratio than the model WIDO-SPRAY and therefore is more suitable to spray compounds over a larger distance or deeper into the buffing wheel for example. The gun can spray between 0.2 and 3 cm3 per shot.
The WIDO-SPRAY model differs from the HDP II. The spray volume is twice as that of the HDP II and therefore especially suited for buffing wheels with a large diameter. The pressure ratio is smaller and the gun sprays softer. The functions of the gun can be monitored electronically. A central valve cartridge includes nearly all wearing parts and can be changed quickly.
