This equipment consists of a venturi pump. Installed on the powder tank, the tube in the air-powder mixture allows for aspiration of the powder in suspension, with the aid of compressed air in the tank, to propel it into the powdering circuit (transport).
- Aspiration tube
- Pump body
- Two air inlets
The two air inlets called “dosing air” and “additional air” have clearly defined roles.
The dosing air: sets the flow rate of powder that the gun must spray to ensure coating of the part.
The additional or transport air: ensures sufficient air speed to obtain regular flow of the powder through the tube up to the gun. It is required when the dosing air is set to a low value.
- Permanent suspension of the powder
- Setting of the volume to be sprayed
- Large capacity
