Bulk Filling

DensiMAX™ Bulk Filling System Spout with Bladder and Pinch Ring Option (SBR)

This option is used when a bag being filled does not have a fill spout or for boxes or bags with liners. The seal surface is formed by a round ring that is attached to the fill spout and creates a fixed surface for the inflatable bladder to seal against when using a non-spouted bag. The opening of the bag is bunched and fed between the outside of the inflatable bladder and pinch ring. The actuation of the cylinders is by an electric solenoid which is activated using a selector switch through a PLC output. The push button operator is located in the fill area convenient to the operator. The construction of the fill spout uses a dual diameter 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 dust removal.



  • Carbon or SS product contact surfaces
  • Inflatable bladder seal with cover sleeve 
  • Dual diameter with annular opening
  • Plunger type push button operator
  • Pinch ring attachment for liners or non-spouted bags
  • 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
