Bladder Tanks Foam Bladder Tanks

Bladder Tanks are the main component in a balanced pressure proportioning bladder tank system, which require no outside power source other than an adequate water supply. The Bladder Tank is a carbon steel pressure vessel with an internal reinforced neoprene rubber bladder resistant to the corrosion of the water and of the foaming agent with which it is in contact. Bladder Tanks are available in both vertical and horizontal versions in multiple sizes and with foam inside or outside the membrane. The Foam Bladder Tank serves as a pre-mixing system through a very simple mechanism: the water coming from the water network pressurizes the tank, pushing the foam concentrate contained in it to a mixer of venturi type. Here, the foam concentrate is in contact with the water, forming the foam mixture that will be channeled to the pipe of the distribution network. A foam bladder tank may have variable dimensions and consequently different capacities of containment of foam concentrate. It’s able to work even with relatively low pressures and ensures minimum pressure losses. Furthermore, the proportioner applied to it can be calibrated according to the delivery system, and the percentage of foam concentrate aspirated remains unchanged compared to the flow.The bladder tank is installed in fixed plants where a high foam protection is required. Synthetic,protein, Alcohol Foam foam compound may be employed.
