Vacuum tanks

Bellaform has already delivered more than 500 vacuum tanks for extrusion systems around the world. The tanks are characterized by a robust and maintenance-compatible design, in which the vacuum is produced via Venturi nozzles. The vacuum tanks additionally have a water collection tank with control and pump that ensure that the cooling water is returned to the cooling system. 

Bellaform offers two vacuum tanks for different product diameters each (25–50 mm). Both versions can be combined easily with any of our extrusion lines.

• The longer retention time permits better diameter control with a longer trough of 3.00 m
• Sufficient space for work on the format set and the calibration tool by increasing the movement range (extrusion direction) to 250 mm. 
• Both chambers are equipped with an electrical temperature measurement and electrical pressure monitor. These data are also displayed and saved for analysis purposes.
• The longitudinal adjustment is motor-powered and can be moved with integrated path measurement
• Within the scope of the complete production data recording, the position is displayed and stored.
• The vacuum tank adjusts independently to a vacuum loaded from the recipe and the matching distance from the spraying head. 
• Manual fine adjustment is possible additionally, which may also be taken over to the product list.
• The tank is moved to the end position in case of faults or stop in order to prevent materials flowing in from being pressed into the calibration tool. 
• The water pump for the Venturi system is speed-controlled
• Only the vacuum that is actually needed will be produced (power saving)
• Noise development will be reduced.
• A constant vacuum is preserved at a low vacuum. 
• Sufficient space to collect „dripping material“ by increasing the front protrusion (extrusion side)
• The product diameter control that has been tried and tested for many years via laser outer diameter measurement and vacuum control has been preserved
