Model 3500XD Air Removal System Without effective air removal, medium consistency pumps will not operate reliably. The efficient air removal system of the Model 3500XD and the simple degas system result in easy operation and very low maintenance. X-Ducer Initiates Flow and Begins Air Separation X-Ducer agitates pulp to assist flow into pump inlet. X-Ducer also separates air from water and fiber. X-Ducer concentrates air core and develops pumping action X-Ducer utilizes conventional technology to concentrate air in core and prepare it for removal. Fiber and water move to the periphery of the...

System Configurations Standpipe Arrangement with CIO2 Mixing Stock from washers, presses and thickeners feed special Goulds standpipes that are reverse tapered to prevent stock bridging. Systems include controls for vacuum, dilution, level and flow. Tower Bottom Arrangement Stock from bleach/storage towers falls into Goulds feed chute connected to the tower with expansion joint and isolation valve. Depending on tower level and consistency, a vacuum pump may not be required. Booster Arrangement Goulds booster pump will increase pressure but does not require standpipe or degassing system.
