Bulk Filling

DensiMAX™ Bulk Filling System Spout with Bladder Option

DensiMAX™ Bulk Filling System Spout with Bladder Option for FIBC Filling is standard for most filling applications. It has a dual diameter fill spout in which the inner diameter is used as a product fill path and the outer diameter is used to hold the fill spout. The annular space created between the inner diameter and the outer diameter is used as the path for the dust removal. On the outside of the outer diameter there is an inflatable bladder (which is covered by a rubber sleeve) that will inflate after the bag spout has been slid over the fill spout.



  • Carbon or SS product contact surfaces
  • Inflatable bladder seal with cover sleeve 
  • Dual diameter with annular opening
  • Plunger type push button operator
  • 2” diameter NPT coupling to connect to the plant dust collection or to add a filter to exhaust displaced air during the filling cycle
  • Coupling is also used to connect the optional isolation valve which is used when dust collection and bag inflation is required. 
  • Top nipple for connection of a flexible boot between the fill spout and the upstream feed equipment or orifice gate valve
