A conditioning system for water based can sealing compounds comprising a downstream pressure regulator adjacent a double diaphragm pump, a filter and a heater wherein the exit of the heater is connected to a lining nozzle, an exit line from the nozzle connected to an upstream pressure regulator and a return line meeting the supply line between the downstream pressure regulator and the pump. Additionally, one or more dampeners may be added to the system as well as various pressure gauges and other sensors. The system without dampeners controls film weights to within +/- 5% of the desired amount. The use of one or more dampeners improves film weight control to wtihin +/- 3% of the desired amount. |
